Threading Peeling

P20WP20 (P10-P35), M15 (M05-M20). A PVD-coated grade with hard substrate giving good edge toughness for steel and stainless steel materials. Combines good wear resistance with edge sharpness.

GC4325P20 (P10-P35). A CVD-coated grade optimized for steel machining with excellent combination of high wear resistance and edge security. This grade is rec-ommended for continuous as well as interrupted cuts and in less favourable conditions.

GC4125 P20 (P10-P40), M20 (M05-M25), S20 (S10-S25). A PVD-coated grade that works well in steel, stainless steels and heat resistant super alloys.

GC1020 P20 (P10-P40), M20 (M10-M30), S20 (S05-S30). A good all-round PVD-coated grade for steel, stainless steels and heat resistant super alloys. Combines good wear resistance with edge sharpness.

GC1125 P20 (P05-P35), M20 (M10-M30), S20 (S10-S25). A PVD-coated grade with good wear resistance in steel and stainless steel materials at higher cutting speeds. Also provides toughness in demanding applications, at lower speeds, when machining super alloys.

GC1135 P25 (P10-P45), M25 (M10-M35), S25 (S10-S35). A good all-round PVD-coated grade for steels, stain-less steels and heat resistant super alloys. Combines good wear resistance and edge line toughness. To be used at medium to low cutting speeds.

GC4315P15 (P05-P25). A CVD-coated carbide grade for finish to rough turning of steel. This grade is recommended for continuous cuts as well as light interrupted cuts. Recommended for high metal removal rates.
