                NLD/NGD type chipbreakers achieve outstanding chip control in semi-and fine-finishing of aluminum alloys. The employment of high toughness grade DA1000 achieves stable, long tool life.

                • PCD insert with chip breaker for aluminium alloys
                • Excellent chip control in finishing applications
                • Improved work efficiency by solving chip control problems
                • Stable long tool life with high-toughness grade DA1000

              • NPD10 BINDERLESS PCD GRADE

              • SUMIDIA grade for carbide and hard brittle material

                The binderless PCD grade NPD10 is our first recommendation for high-precision machining of tungsten carbide as well as hard and brittle materials.

                • Excellent wear reasistance
                • Extreme performance due to nano-polycrystalline diamonds offering superior dimensional stability
                • Reduces tool replacing time compared to conventional tools
                • Great advantages in improving work quality and achieving total cost savings by higher productivity

              • ANX HIGH-SPEED CUTTERS PCD

                • Cutter body as shank and shell type available
                • Standard / Medium / Fine pitch
                • Wide milling cutter range with diameter from Ø 32mm to 160mm

            • SUMICRYSTAL

            • SumiCrystal ® is synthetic single diamond which is suitable for the machining of industrial materials.

                  • SUMICRYSTAL FOR MACHINING OF INDUSTRIAL MATERIALS

                  • SumiCrystal is synthetic monocrystalline diamond, that Sumitomo Electric manufactures under strict quality requirements. Diamonds are famous for being the hardest known material offering a maximum of heat resistance. Due to these characteristics combined with low thermic spread and high electric resistance diamonds are important for today's high-precision technologies. Compared with natural diamond SumiCrystal shows up an excellent uniformity of product characteristics and is therefore very much suited for industrial applications.
