Domestic GMM Series Slot Blade 2020-MT 3020 R--15D KPR930

GMM-MT Series KPR930 Carbide CNC Grooving & Parting Insert for Steel & Stainless Steel

This domestic GMM series grooving insert covers GMM2020-MT, GMM3020-MT straight-edge models and R-MT-15D radius-edge model, with MT-type universal chipbreaker geometry. Matched with premium KPR930 PVD carbide grade, it serves grooving, parting and slotting on steel and stainless steel via CNC lathes.

The KPR930 grade features advanced nano TiCN-based PVD coating with exceptional anti-adhesion and wear resistance, effectively suppressing built-up edge and crater wear in continuous cutting. The optimized MT chipbreaker ensures steady chip formation and smooth evacuation across wide feed and depth ranges.

Its double-edged structure delivers 2 usable cutting edges per insert for solid cost efficiency in mass production. Precision machined to standard GMM interface dimensions, it fits common GMM grooving holders and is widely used in automotive, machinery, valve and hardware industries.
