Precision-Ground Carbide Construction: Engineered with ultra-fine grain tungsten carbide for exceptional wear resistance and edge retention in high-speed steel machining applications.
Micro-Grain Cutting Edge: Features a razor-sharp 0.2mm radius (6R0.2) for ultra-precise finishing cuts, eliminating secondary polishing in tight-tolerance steel components.
Swiss-Turn Optimized Geometry: Patented 22mm flute length (L22) balances rigidity and chip evacuation, ideal for CNC lathes handling aerospace-grade alloys or medical implant steels.
Multi-Pass Reliability: Cryogenically treated shank resists thermal deformation during prolonged heavy-duty turning of hardened steels up to 62 HRC.
Interchangeable Insert System: MPR modular design allows quick cartridge changes for uninterrupted production of automotive camshafts, hydraulic cylinders, and precision gears.
Surface Finish Guarantee: Mirror-polished rake face reduces built-up edge for Ra<0.8μm finishes on stainless steel, tool steels, and nickel-based superalloys.
