Tungsten steel step drill (also known as carbide stepped drill): with high hardness, wear resistance, strength and toughness better, heat, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance.
Tungsten steel step drill (carbide step drill) can quickly achieve drilling + chamfering a one-time molding, especially for the bottom hole drilling and chamfer.

The use of ultra-fine particles of tungsten steel, toughness and hardness of the perfect combination. Mainly used for copper, aluminum, iron and other materials easy to drive the hole of the processing.

We can produce all kinds of tungsten steel (carbide) drill bits and other tungsten steel cutting tools, stepped drill, twist drill, center drill, fixed point drill, all kinds of non-standard forming drill; can well deal with stainless steel, aluminum processing Products surface finish is good, can also be processed other types of steel. Welcome to plans to build processing.
