The bit body adopts 42CrMo, it is produced by cnc machine to guarantee the size same.Then the carbide tips are brazed to the bit body after filling the solder to the body.
Some manufacturers in order to reduce their cost, they use low quality carbide tips and carbon steel as the bit material, and their bit body is casting, this type bit body has much more tolerance. In order to make the carbide tips to insert the bit body, they fill too much solid to the insert hole. Thus when the conical bit use with coal crusher, the tip is very easy to fail from the bit body.
