Tungsten Carbide Mining Conical Buttons / Conical Cutting Bits for Gas Mining
As we know, tungsten carbide conical buttons are produces with two parts: alloy steel body and carbide drill tips. The alloy steel body is made by material ASTM4142 or 42CrMo, whose heat treatment is 48-52HRC hardness. They has high toughness and wearable character. Tungsten carbide drill tips are made from Low press sintered with grade selected according to your projects, which can make sure good performance during working.
Our factory can provide the customized conical carbide bits, complete colat auger bits, coal drill bits, blade cutter bits. At the meantime, our factory can provide the customized surface coating to the bits.
Advantage of the tungsten carbide conical buttons
The tungsten carbide conical buttons are made of top-quality virgin raw materials from reliable suppliers in China. Those tungsten carbide conical buttons are produced with precision molds to get high accuracy for the finished products. What's more important, our factory can produce the special tungsten carbide drill tips meetibg every customers' drawings exactly.
