Our company can provide you with these specifications: 
For other specification, we can customize upon request.

We can supply all kinds of coal mining bits, flat cutter teeth with sleeves and holders, shearer picks, round shank bits with holders, welding bar, etc use for drill auger, which have high strength, high wear resistance and long life features. They are widely using on foundation drilling tools, excavation machines, shearers, continuous mines etc. Also we can make them according to your drawing or samples, we assure that we will give you high quality products with lowest price. 
 
We choose high quality steel, and high quality tungsten carbide tip via forging, welding, heat treatment. Steel body, made by material 42CrMo, heat treatment with 40-44HRC hardness, has high toughness and wearable character. Tip is made by material tungsten carbide, and Suitable Grade Selected according to the Target Projects, Which are to make sure the good performance during working.
