GROOVE-TURNTEXT CERMETUNCOATEDCBNPCD USER GUIDE ISCAR Groove-Turn Grades Chart Grade ISO Grade Description Coating Layers Uncoated P05-P25 M05-M15 A very hard cermet grade for turning and grooving, recommended for finishing operations on steels and alloy steels at high cutting IC20N speeds and low feeds. Features excellent surface finish, high wear resistance, plastic deformation durability and prevents built-up edge. Base A very hard-uncoated carbide grade, suitable for machining IC4 aluminum alloys, aluminum alloys with high silicon content and N01-N15 other non-ferrous materials at high cutting speeds. S05-S15 Base M10-M20 A hard-uncoated submicron carbide grade, suitable for IC07 machining aluminum alloys and other non-ferrous materials N05-N20 at high cutting speeds. S10-S25 Base M15-M30 A tough uncoated submicron carbide grade, suitable for steels, IC08 stainless steel and high temperature alloys at low cutting speeds. N10-N25 Good choice for non-ferrous materials. S20-S30 Base A hard-uncoated carbide grade for machining aluminum and K10-K20 other non-ferrous materials at medium to high cutting speeds. IC20 Can be used for cast iron at low cutting speeds. N05-N25 Suitable also for machining high temperature and Titanium alloys, S10-S20 at low cutting speeds. H10-H20 Base IB10H Extra fine PCBN grain size. Suitable for high speed machining ofhardened steels (45-65 HRC) under stable conditions. H10 Base IB20H A combination of coarse and fine PCBN grain, suitable for generaland interrupted cutting of hardened steels. H20 Base K01-K10 A PCBN grade, suitable for finish turning and grooving operations IB50 on hardened steels 45-65 HRC and nodular cast iron in continuous cutting. H01-H10 Base A PCD brazed tip, suitable for machining aluminum alloys (Si < 12%) and other non-ferrous materials. Features very high ID5 wear resistance with high toughness. Suitable for finishing N01-N10 operations and can be used for semi roughning operations and interrupted cut. Base 436 ISCAR
