description: Kyocera GDM3020N-025PM PR1225 Grooving Insert | 3.0mm Width (GDM 3020N-025PM) 1. Product Overview Which grooving and parting insert is best for precision shallow grooving, side turning, and eliminating chip packing in stainless steel and alloy steels? The Kyocera GDM3020N-025PM PR1225 (Imperial / ANSI Equivalent: GDM 3020N-025PM) is a double-ended 2-edge precision grooving and cut-off insert designed for high-performance shallow grooving, profiling, and light grooving-turning operations. Powered by Kyocera’s flagship PR1225 MEGACOAT PVD Coating Grade, it combines a micro-grain carbide substrate with a high-hardness TiCN/TiAlN physical vapor deposition layer, providing superior thermal stability, oxidation resistance, and edge line sharpness. Engineered with the specialized PM Medium-Cutting Chipbreaker geometry, this insert features an optimized 3D rake angle that tightly curls and narrows chips smaller than the groove width. This prevents sidewall scratching, eliminates chip packing, and ensures smooth chip evacuation across grooving depths up to specified holder limits at feeds (fn) from 0.05mm to 0.18mm/rev. 2. Product Key Features Double-Ended 2-Edge Design: Provides 2 precision-ground cutting tips per insert, doubling tooling economy for grooving and cutoff setups. MEGACOAT PR1225 Grade: Advanced PVD coating engineered for superior heat resistance and built-up edge prevention in ISO M stainless steel and ISO P steel. PM Chipbreaker Geometry: Curved 3D rake structure actively narrows chips during radial grooving and lateral turning to prevent chip jams and sidewall scoring. Precision Corner Radius (0.25mm): Small corner radius reduces radial cutting forces while maintaining precise groove corner geometry and sharp radii specs. High Rigidity Clamping Alignment: V-shaped top and bottom seating surfaces ensure exact repeat accuracy and zero lateral deflection under axial side-turning loads.
