SOLLROC/M40 4-Inch DTH Bit for Mining and Construction Works

The bit is the tool cutting the rock, and no hammer or rig drilling is better than the bit it uses. The down-the-hole bit is subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration. In such cases remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life.

1.Simple and reasonable design, easy to assemble and dis-assemble, low problem rate. 

 2.Low air consumption, smooth drilling, maximum impact power, high penetration rate.

3.Multiple precise heat-treatment with all hammer parts to provide longest lifespan under
roughest working conditions.
