4''-120mm DTH Drill Bit for Medium Hard Formation with High Performance Down The Hole Bit

Sollroc DTH bits are engineered for superior penetration while maintaining maximum cleaning action at the bit face, extending product lifespan. Manufactured using premium aircraft-quality alloy steels and proprietary treatment processes for maximum durability.

• Concave Face: Ideal for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and flushing capacity.
• Convex Face: Delivers high penetration rates in soft to medium-hard formations with low to medium air pressures. Resistant to steel wash but offers poor hole deviation control.
• Flat Face Bit: Designed for hard to very hard, abrasive rock formations with high air pressures. Offers good penetration rates and steel wash resistance.
