        NC6310 / NC6315
        Cast iron is sorted into ductile cast iron and gray cast iron and commonly used in automobile and machinery components which require high heat resistance, corrosion resistance, and wear resistance. Cast iron embraces spheroidal carbide containing silicon (Si) and magnesium (Mg) so built-up edge and chipping can easily occur while machining. In contrast, gray cast iron includes acicular carbide so it produces better machining than ductile cast iron. However, cast iron workpiece is easily affected by manufacturing and external environment after casting process so its property is prone to be unstable.

        Tool life of the existing CVD grades for cast iron turning is unstable due to the precarious property of workpieces causing rapid wear and chipping on the cutting edge. The unstable tool life is one of the worst obstacles of customer’s high productivity so KORLOY focused on developing the technology of the CVD coating and chip breaker shape for stable and long tool life and thus finally launched grades, NC6310 and NC6315 and chip breakers for customer’s satisfaction.

        NC6310 is a K10 turning grade for high speed with continuous or light interrupted condition which enhances the wear resistance and stable tool life.
        NC6315 is a K15 grade for general machining of gray cast iron and ductile cast iron and provides stable tool life in various kinds of machining such as high feed, heavy interrupted, or continuous cutting.
        Chip breaker, MK (negative, for medium cutting) reduces cutting load and enhances surface finish. It is suitable for general machining. Chip breaker, RK (negative, for roughing) provides stable tool life even in heavy interrupted machining due to its strong rigidity of the cutting edge.

        Both of MK and RK provide stable tool life even under any extreme cutting conditions due to unstable clamping of inserts and holders.

        PC3700

        In general, flank wear and crater wear are caused for steel milling due to frictional heat between workpiece and tool. While applying high depth of cuts or high feed for Pre-hardened steel, chipping and breakage are generally happening. It is also common that plastic deformation of tool for continuous machining at high speed due to heat evacuation, and Thermal crack of a tool at high speed interrupted or wet condition which boosts repeated contract and expand of a tool to lower its tool life. In case of machining a workpiece with deposition feature or milling at low speed, built up edge would easily be caused to a tool, and it would lead to flake or chipping of a tool to lower its tool life. When it comes to the milling applications of steel, it is hard to expect the life of inserts as it comes to consider various machining factors including various types of workpiece, high speed, depth of cut and high feed. Therefore, a grade specialized for milling of steel should provide stable tool life under various cutting conditions and different workpiece types.

        KORLOY’s newly launched PC3700, a unique milling grade specialized for steel, provides advanced performance and satisfactory efficiency. In comparison with current PC3500 and PC3600 grades, wear and breakage resistance of PC3700 has been significantly improved so it ensures extended tool life as well as high productivity and stability.

        The PC3700 features hard and lubricative coating layer with a smooth surface so that chips can be evacuated easily at high speeds, and flank and crater wear will be significantly reduced. It also has minimized build-up edge issues to prevent chipping and improve surface finish. As a highly tough substrate specialized for steel cutting has been implemented, PC3700 inhibits thermal cracking in the interrupted or wet machining process. Furthermore, it provides outstanding chipping and breakage resistance under heavy cutting loads including high depth of cuts and high feeds or pre-hardened steel machining.

        PC3700 provides great machining efficiency and production stability due to its stable tool life for every milling process from high-speed, high-feed and deep machining to continuous or interrupted machining of various steel workpieces.

        • Stable Tool Life
          - Optimized PVD coating for cast iron minimizes tool life deviation

        PC6510
        Cast iron has characteristic that tends to be scattered as broken chips while milling machining. Wear is generated more rapidly at the relief surface where the contact time with the workpiece is relatively longer while the cutting load on the flank surface is low. To machine cast iron, wet condition is generally applied due to heavy dust as the cast iron contains graphite. While machining, cutting fluids keep causing Thermal shock to heated inserts and it leads Thermal crack at the insert's edge part. In addition, Built-up edge is another factor that lowers tool life.

        Now KORLOY offers a new milling grade to provide more stable machining for cast iron.

        New PC6510 has been implemented optimized PVD coating to prevents Thermal crack, and its after treatment improves its surface roughness that minimizes built-up edge case.

        PD1005 / PD1010
        Non-ferrous metals such as aluminum and copper have relatively low melting points, causing heavy welding on the tool edges during machining. The dulled cutting edges bring about poor suface finish of workpieces while high cutting load increases the chance of sudden chipping, resulting in unstable tool life. To provide our customers with a satisfactory grade solution for non-ferrous metal machining, KORLOY has developed DLC (Diamond-Like Carbon) coated grades.

        PD1005 is a grade for workpieces made of aluminum or copper, and for continuous cutting.

        NC6315
        Cast iron refers to ferrous metal that contains more than 2% of carbon and can be sorted into ductile cast iron and gray cast iron. Ductile cast iron is commonly used in automobile and machinery components which require high resistance to heat and corrosion. Ductile cast iron is known for damage on cutting edge due to chipping on the rake and flank surface of an insert, or welding, more frequently than gray cast iron, it’s spheroidal carbide contains silicon(Si) and magnesium(Mg) easily causing built-up edges between the tool and chips. Moreover it is prone to age hardening, the hardness of a cast iron workpiece increases at room temperature, or unstable tool life according to seasons. In contrast, gray cast iron is an acicular carbide readily cutting chips and causing less built-up edges than ductile cast iron.

        NC6315 is a K15 grade with largely enhanced resistance to chipping and wear in high feed and highly interrupted machining of ductile cast iron and gray cast iron. It secures stable antifracture capability even with highly interrupted cast iron materials and with severe vibrations, making good use of the combination of a universal grade and new CVD coated layers.

        MK chip breaker improves cutting performance and reduces cutting load during cast iron machining, leading to higher wear resistance and quality surface finish at high speed and continuous cutting. A wide supporting area was designed for solving unexpected tool breakage and edge chipping due to vibrations during machining, improving stability.

        RK chip breaker features wide lands and supporting area that provide excellent toughness and fracture resistance under high cutting force such as high depth of cuts or high interruption. Its land was engineered to optimize edge toughness and cutting performance, and achieve stable tool life and higher chipping resistance for high feed applications.

          - Combination with high feed tools will deliver higher productivity and stable tool life in high feed and high hardness machining

        PC2505 · PC2510
        Machining workpieces with high hardness over HRC40 generally involves rapid tool wear due to friction between tools and workpieces. Machining speed should be lower due to high impacts caused by high hardness of workpiece. But lower speed cutting may cause built-up edge and chipping which affect shortened tool life.

        KORLOY provides an advanced milling solution for machining those high hardened steels.

        The PC2505 is a grade for workpieces with ultra high hardness. Its excellent wear resistance helps extend tool life when machining pressed die steel and heat treated steels of high hardness over HRC45.

          - Prevents built-up edge, notch wear, plastic deformation, and burr creation

        NC9115 · NC9125 · NC9135
        The reason Stainless Steel is often considered a hard-to-cut material is its large shearing resistance that can easily cause work hardening, built-up edges, and edge fracture. Its combination of tough and hard material characteristics require the prudent selection of grades and chip breakers. These challenges led KORLOY to develop the CVD coated turning grade series, NC9115 / NC9125 / NC9135 along with new chip breakers MM (for medium cutting) and RM (for roughing). The NC9100 Series can solve most Stainless Steel machining problems with its combination of three layers – the top coat protects against welding, the coating layers protect against wear even at high speeds over 150m/min, and the tough substrate against chipping.

        The MM chip breaker for medium cutting is the 1st recommended for stainless steel. Its dual angle land design allows for both sharp cutting performance and strong cutting edges, which promotes extended tool life and minimized cutting force and built-up edge. In addition, wide chip pockets prevent chips from interrupting the minor cutting edges and instead lets the chips out of the cutting area. These chip breaker features help prevent plastic deformation and excessive wear.

        The RM chip breaker for roughing is recommended in rough machining and in cases where burrs are an issue. It has a wide land and rake angle lowering cutting resistance. Cutting heats can flow around the gentle slope of rake surface and can be effectively dispersed and evacuated at high feeds and high depths of cut.

        CN1500 · CN2500
        Cermet tools are commonly applied when machining carbon steels. These applications frequently result in crater wear on the rake surface of insert and chipping caused by built-up edge. This occurs because carbon steel has a lower hardness than alloy steel and has a higher tensile strength, which often results in built-up edge.

        This new P15 cermet grade, CN1500, was engineered to provide improved stability in turning applications at high speeds and when finishing. Wear resistance and anti-chipping have been significantly improved and crater wear on the rake surface of insert is largely prevented in the continuous machining of carbon steel and alloy steel. This can result in up to a 30% increase in tool life compared to conventional tools with test results that show a 1.6 times improvement in surface finish.

        To expand on the excellent performance of CN1500 at high speed and continuous cutting of carbon steels, CN2500 was developed for machining various workpieces such as cold / hot forging steel and sintered ferrous materials.

        This new CN2500 grade has a specially sintered uniformed micro grain matrix to improve stability even in the toughest machining conditions, like heavy interruptions, high feed, or severe vibrations. Test results of surface roughness showed a 1.4 times improvement with CN2500.

          MS Chip Breaker
          As industries keep being advanced, the demand for unmanned automatic lathe and machining hard-to-cut materials for small sized precise components have been increasing. Especially, pure titanium (Grade 3 and 4) and titanium alloy (Ti-6Al-4V) used for high precision parts such as implant are having poor machinability due to high cutting heat and welding which requires high precision and good surface finish.

          KORLOY newly launched a chip breaker, ultra-precision MS for Auto Tools realizing high machinability in ultra-precision components such as implants made of hard-to-cut materials machining.

          The MS chip breaker applied special 3D structured design to enhance chip evacuation function per variation of cutting depth and implemented high precise grinding process to actualize detailed nose R shape with sharp edge. With these, it could minimize cutting heat and built up edge occurrence while machining titanium.

          It also prevents micro chipping by adapting ultra-fine substrate which equalized refined structure. Special surface treatment added PVD also ensures excellent surface roughness and enhanced tool life with high hardness and great anti-oxidation.

          Besides, tight tolerance and deviation management in producing inserts for minimizing dimension deviations of corners and products provide convenience to users as it allows to users not to concern about tool offset in changing insert corners.

          The MS chip breaker would provide the best solution to customers in necessity to precisely machine hard-to-cut materials with combination of premium level management in design, manufacturing, and quality, and grades matching like PC8100 and PC5300 having high hardness and thermal resistance.

          KHP Coolant
          The HRSA (Inconel, titanium and stainless steel) have high strength and low thermal conductivity used in the space, aircraft, and offshore machining industries, results in structure failures causes chipping on the cutting edge due to heat shock and work hardening and decreases tool life rapidly in machining.

          The existing coolant spraying to wide parts is not able to reduce the focused heat on the cutting part in HRSA machining effectively.
          Therefore, to improve the productivity with high efficient cooling, a solution is needed. That is spraying the high pressure coolant directly on the cutting edge.

          KHP Coolant will have the optimal distance between the insert cutting edge and the jet orifice, the ideal place of the streamlined jet orifice of the coolant. KORLOY’s new KHP sprays high pressure coolant enhancing chip control and wear resistance.

          • Solutions for most common issues in stainless steel machining
            - Prevents built-up edge, notch wear, plastic deformation, and burr creation

          MM · RM Chip Breaker
          The reason Stainless Steel is often considered a hard-to-cut material is its large shearing resistance that can easily cause work hardening, built-up edges, and edge fracture. Its combination of tough and hard material characteristics require the prudent selection of grades and chip breakers. These challenges led KORLOY to develop the CVD coated turning grade series, NC9115 / NC9125 / NC9135 along with new chip breakers MM (for medium cutting) and RM (for roughing). The NC9100 Series can solve most Stainless Steel machining problems with its combination of three layers – the top coat protects against welding, the coating layers protect against wear even at high speeds over 150m/min, and the tough substrate against chipping.

          The MM chip breaker for medium cutting is the 1st recommended for stainless steel. Its dual angle land design allows for both sharp cutting performance and strong cutting edges, which promotes extended tool life and minimized cutting force and built-up edge. In addition, wide chip pockets prevent chips from interrupting the minor cutting edges and instead lets the chips out of the cutting area. These chip breaker features help prevent plastic deformation and excessive wear.

          The RM chip breaker for roughing is recommended in rough machining and in cases where burrs are an issue. It has a wide land and rake angle lowering cutting resistance. Cutting heats can flow around the gentle slope of rake surface and can be effectively dispersed and evacuated at high feeds and high depths of cut.

          MP Chip Breaker (Positive)
          The surface of forged steel that is commonly used for automobile parts is hard and tough while the inside is soft. Bearing steels also have the same characteristics of high toughness and hardness. Machining these kinds of steel repeatedly causes built-up edge and edge chipping, which is one of the main causes of reduced productivity and unstable tool life. Mass production of automobile parts requires faster cutting speeds, higher feeds, and much longer tool life than ever before.

          KORLOY has recently released a new ISO single-sided MP chip breaker that shows excellent performance in internal machining of automobile components. It provides stable chip evacuation and tool life by the use of insert geometries specialized for machining forged steel, bearing steel, etc. The MP chip breaker is the best solution for automobile components as well as general machine components.

          The single-sided MP chip breaker reduces cutting loads due to sharp cutting edges and wide chip pockets when machining outer surface of hardened materials such as forged steel. Its special three dimensional geometries enables smooth chip evacuation by producing good chip curls even on rugged surfaces.
          In addition, it largely contributes to increased productivity with the expectation of stable tool life and excellent surface finish.

          Mass production of automobile parts requires faster cutting speed and higher feed along with much longer tool life than before.

          LP / MP Chip breakers have two step dots at the corner and bring measurable increase in productivity when machining forged steel at high speed(max. 350m/min) and high feed(max. 0.35mm/rev).

                TP2P


                The accelerated development of industrial structures has complicated the forming of the workpiece shapes more than ever before. The clamping area for a jig or a vise becomes narrow and leads to tool vibration and imperfect machining conditions. Workpiece materials are also evolving to hard-to-cut materials and high hardness in order to achieve higher durability for industrial components. This is often said to be the major cause of shortened tool life and unexpected tool breakage in many modern metal cutting applications. So companies dealing with unstable workpiece clamping and hard-to-cut materials has a growing demand for cutting tools that are able to solve these problems.

                TP2P responds to these demands by using the tangential clamping system and wedge-shape inserts to improve the clamping stability of the tool itself. Therefore unstable clamping of the workpiece can be off-set by a strong clamping force of the tool. In addition, a sharp chip breaker and high helix angle were applied to the insert design for stable cutting performance in hard-to-cut materials and high hardened workpieces. These design details lead to exceptional increases in tool life.

                Additionally, the tangential-type clamping system facilitates securing chip pockets and enables multiple-corner use to boost productivity. TP2P features low force cutting performance even at high speeds and high feeds thanks to its optimized blade design that effectively reduces vibration and cutting resistance during operations. Now productivity can be improved over non-tangential designs by more than 30% due to increases in table feeds, stable clamping, and high speed/high feed rates.
                The Tangen-Pro TP2P shows excellent performance in P, M, K type materials with its specialized design and grades developed specifically for the most challenging metal cutting applications.

                HFM

                The need for high feed tooling has grown while the materials of molds tend to be harder. Small size tooling is required for the electronic parts and mold manufacturers to achieve high productivity.

                However, increasing productivity has been restricted due to the absence of small size high feed tools for high hardness steel.

                HFM extends the range of process to small diameter, improving productivity with more number of teeth, compared to HRM(D).

                High Helix angle on the cutting edge reduces cutting resistance, while the negative axial rake angle of holder reduces the contact surface on workpiece, reducing wear and vibration and increasing stability. Improved grades ensure stable tool life. Ultrafine grain substrate and specialized coating layer highly improve anti-chipping and anti-wear.

                Aero Mill-Plus

                In the case of the adjustment method for conventional blades, inserting a wrench into the small groove of the adjustment screw for fine-tuning made it difficult for operators to adjust in dark environments, such as at night. The wrench that fits to the small groove also has weak stiffness, thus making it easy to become bent.
                As a result, the concept of a spanner was introduced to allow for more convenient adjustment to ensure adjustment in dark environments and increase the rotation angle with an operator-centered approach.

                In addition, components were simplified, securing the maximum number of blades for productivity improvement.
                This resulted in up to 40% reduction of setting time compared to the previous method.

                Aside from this, in order to address risks following the simplification of components, the structure was supplemented to prevent the blades from departing in the cutter rotational direction in the event of damages that may have occurred on the screws for fastening blades or other problems, while it was rebuilt to flow up and down with the direction of the cutter.

                Aero Mill-Plus integrated the chip cover and the blade. To improve the chip interference on the chip cover and PCD life, a direct application system was applied, and it increased the life of the cutter by up to 20%.

                RM3

                In this industry, requirements such as reducing manufacturing cost and improving quality are constantly in demand. This means cutting tools for mold making would have to achieve both factors. Tools must achieve high productivity and quality in a variety of applications, notably in the mold making industry, in various applications: shouldering, facing, slotting, plunging, etc. If cutting tools should have to be replaced with every application, both productivity and cost efficiency would get worse. This led KORLOY to develop the RM3. A tool specifically engineered for true perpendicular shouldering, with multi-functional capabilities.

                To use a single tool for various applications requires not only sharp cutting action but high rigidity and stable clamping. Poor cutting performance leads to excessive noise and burrs, and deteriorates both the perpendicularity and the surface finish. Low rigidity and unstable clamping cause vibration during operations leading to insert chipping or breakage, which shortens the tool life.

                The RM3 solves all these problems and delivers higher machining stability and excellent results in quality. This 3 corner insert shouldering tool exhibits a proprietary insert design with high rake angle chip breakers & cutting edges for sharp cutting action and low cutting resistance.
                It additionally features a holder rigidity 2 times stronger than the existing tools, which allows a stable machining even in the toughest cutting conditions. There were lots of actual test reports that the RM3 significantly improved our customers' cycle time thanks to its high rigidity and clamping system in operations such as shouldering, ramping, facing, slotting and plunging. Even in high feed milling applications, the RM3 showed no sign of tool failure.

                The RM3 also takes advantage of the true perpendicularity that largely improves surface finish. A variety of grades are prepared for machining applications in steel, cast iron, hard-to-cut materials and more. RM3 markets itself as a versatile leading milling tool that meets demanding performance and capacity requirements.

                FMR P-positive

                There is a growing interest in fashioning cutting tools for mold making that can be both cost effective and capable of excellent delivery. In its current state, the mold making industry has a range of applications spanning shouldering, facing, slotting to plunging. The downside of all these assorted tools is the risk of compromising productivity and cost efficiency if they were to be replaced individually. It is with this in mind that the FMR P-positive comes to the rescue because of its purpose built capacity to work through high hardness mold steel and heat resistant steel in rough milling. This unique feature is what distinguishes it from the existing FMR D-positive.

                The FMR P-positive is available in most applications. In case of dealing with cut depths of less than 0.039inch depth, cutting angle is formed under 15° for high feed milling. It also has high depth cut capabilities of up to half the insert size(0.157~0.394inch). High depth cut and high feed machining allow for increases in productivity. That is because high feed tools form thinner chips in the same feed condition, which helps reduce cutting force. The FMR P-positive would be an ideal choice, particularly when you want to improve productivity or use low horse power.

                The New FMR P-positive inserts are a comprehensive cost effective device. It features reinforced rigidity by applying a relief angle of 11°. Relief surfaces of 18° have been included to prevent interference by feeds. 4 to 8 out of the relief surfaces are isotropic designed to provide a large relief angle around the circumference, to prevent anti-rotating often resulting from machining with the R-type insert.

                In mold making, a shank type that has a long body of a large aspect ratio over 2D is commonly used. The large aspect ratio is vulnerable to tool vibration even under low cutting load that may even result in tool breakage in extreme cases. To resolve this problem, the FMR P-positive forms a negative axial rake angle. With the use of the negative angle, both wear on rake surfaces and the contact area on workpieces are reduced to minimize tool vibration.

                The FMR P-positive also results in increased effective diameter and faster cutting speeds (In case of ø32-6R, 1.6 times faster), and a wider turning radius. All of these will lead to stable machining right from the onset even when dealing with a ratio of 6D in order to finally deliver higher productivity.

                  Super Endmill For HRSA

                  HRSA, a material with higher strength at high temperature and corrosion resistance than general alloy, is commonly used for aerospace engine and parts of generator turbine.

                  HRSA is divided into Ni Based, Ni-Fe Based, and Co Based heat resistant super alloy by elements and Ni Based heat resistant super alloy such as Inconel718, Hastelloy, Waspaloy and etc. is most generally used.

                  HRSA is a representative of hard-to-cut materials causing short tool life due to work hardening, low thermal conductivity and high-temperature strength.

                  Low thermal conductivity makes increasing cutting speed impossible due to generating high temperature while machining at the edge.
                  Maintaining high strength at high temperature and work hardening also cause rapid wear, breakage, and severe damage on the edge of cutting tools.

                  KORLOY launches Super Endmill, the most effective tool for hard-to-cut material in HRSA machining.

                  Composite Router Endmill

                  With a growing number of environmental regulations and the increasing demands for higher efficiency and lighter weight, more and more composite materials have been used in various industrial fields such as automotive, aerospace, wind power and energy industries.

                  A composite material is combined materials of two or more kinds for better machining properties. Typical examples are CFRP(1) consisting of carbon fiber and resin, and GFRP(2) consisting of glass fiber and resin. They are light and have excellent mechanical properties featuring strong resistance to corrosion and fatigue.

                  Unlike general metals, CFRP and GFRP generate large amounts of chips in the form of scraps. Due to the high hardness and low thermal conductivity of the fiber-reinforced materials, high-temp cutting heat is generated during machining and tools wear out rapidly. In addition, their high strength, high elastic modulus, and inhomogeneity between dissimilar materials cause excessive vibrations, and the composite structures cause machining troubles such as delamination, splintering and burrs.

                  KORLOY’s diamond-coated grade ND2100 features a nano-crystalline diamond coating that has strong resistance to wear and friction, resulting in outstanding tool life.

                  D Endmill

                  Cutting tools made for graphite tend to have poor tool life during machining. Friction between graphite molecules and the relief surface of endmill cause early tool wear, and its high hardness is also responsible for the possible flaking of the diamond coating.

                  It is therefore important to develop a diamond coating that has high hardness and good adherence to the substrate. In return, this will reduce the occurrences of tool wear and flaking, resulting in an increased tool life.

                  The ND3000 is a new diamond coated grade with high hardness and high purity sp³ structure that improves wear resistance. It also offers higher resistance to flaking since it holds the coating and the substrate tightly together.

                    Mach Solid Drill

                    • 3D, 5D, 7D Standardization: For example) diameter Ø10mm and depth 30mm and outer coolant system, Take MSD100-3P!

                    • MSD: Solid type & MSDH: Through oil-hole type: Various designations of MSD & MSDH enable to do any drilling

                    Advantages
                    • Optimally designed chip pocket
                      - Wide and deep chip pocket improve chip control to minimizing friction during an operation
                    • A curvilinear edge
                      - A curvilinear edge offers excellent wear resistance and shock resistance by dispersing the cutting load
                    • Low cutting resistance edge
                      - The MSD & MSDH low cutting resistance edge guarantees a better surface roughness and chip control while allowing the drill to center itself
                    • Rigid neck of drill
                      - The new design of this drill has an increased rigidity at neck. This prevents breakage of neck on the drill
