Straight handle attachable drill bit

Specifications

Imported super high wear-resistant high-grade high cobalt powder steel, quenched treatment:HRC70°±2°, with excellent wear resistance and impact resistance. Comparing with HSSEHSS-AL and HSS-Co, it has 4~8 times lifetime, and can guarantee uniformity and conformity rate of machined products. It is often applied in general equipment for machining various materials including NiCrMoSiTi) that are hard to machine like high temperature alloyheat-resistant alloycast iron of nickel-vanadium-titanium alloystainless steel. It is excellent machining tool before heat treatment. It has excellent high temperature machining and comprehensive performance, and allows higher cutting speed. The higher the hardness of machined materials, the more remarkable the effect. Because its roughness is not so good, it is not suitable for discontinuous cutting or for using under processing system of insufficient rigidity, otherwise, cutter will be hit or chipping will happen.

VRA201: Imported ultra micro-grain diamond tungsten steel, with excellent impact-resistance and general wear-resistance. Generally applied in worse or general equipment to machine materials of lower hardness HRC≤25°, discontinuous cutting and worse part fixture. Conforming to ISO K25, can replace machining of materials like M42, ASP60, MPM, HSSCo10 etc, and can get 4-6 times lifetime, it has higher performance/price ration. Comparing with SKH51, it has 15-25 times lifetime and durability
