Micro 65 Degree CNC Blade Small Diameter Carbide L22 Quenching Parts Stainless Steel MPR Small Hole Boring Lathe Boring Tools
This MPR 6R0.2 L22 micro boring-turning tool adopts solid tungsten carbide substrate with high-hardness nano-blue coating. Its 65° cutting angle and 6mm rigid shank deliver outstanding cutting rigidity for small-hole machining of hardened steel and stainless steel on Swiss-type lathes.
Precision-ground R0.2 nose edge ensures stable cutting and smooth chip evacuation in confined inner bores. The wear-resistant nano-blue coating effectively suppresses built-up edge, guaranteeing consistent dimensional precision and premium surface finish for hardened workpieces.
Offered in a full range of sizes for diverse bore depth requirements, its compact profile perfectly adapts to narrow machining spaces. It prolongs tool life, reduces tool-change downtime, and greatly lifts overall productivity for miniature hardened component mass production.
