Welding Percussion Drill Bits, Tungsten Carbide Inserts ,YG4C,YG8,WC,Cobalt

Description:

1. HIP sintering enhances the hardness, ensures good impact resistance.excellent wear resistance and bending strength.
2. Mainly used for strips,conical buttons for rotary percussion resistantance.
3. It can be welded on rotary burs to drill steel, iron and etc.
4. We provide OEM and ODM services.
