Tungsten Carbide Buttons Produce ProcessTungsten carbide buttons mainly 4 steps on processing: Grinding, pressing, sintering and quality inspection1, Using mold experiment to prepare the accurate raw

In addition to the correct choice of carbide grades, rock drilling efficiency is also affected by many factors, mainly the shape of the bit, rock hardness, compressed air pressure, powder discharge method, blasthole diameter and blasthole depth.

Tungsten carbide buttons also named tungsten carbide tips and tungsten carbide teeth. Tungsten carbide buttons have their unique working properties, so they are widely used in oil drilling and sn

According to different rock formations, select different types of DTH drill bits, shaft pressure and rotation speed according to the softness and hardness of lithology.

Top hammer button bits​ have thread button bits and tapered button bits.The material is tungsten carbide button with steel body. Thread button bits are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (air drill rods). The drills are drilled by different types of threads and the drill rods. ¢32-¢203mm, mainly used in the mining of underground mines, the mining of open pit mines, the opening of blast furnaces in steel mills, etc.
