sollroc DTH bits are designed and manufactured for superior penetration while maintaining maximum cleaning action at the face of the bit, thus extending the working life of the products. They are manufactured utilizing premium aircraft quality alloy steels coupled with sollroc's proprietary manufacturing and metal tretment proccesses, which allow for the longest possible product life.
Bit face shape selection:
1. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
2. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
3. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
