Product Description

Welcome to our homepage: https://cnfirip.en.made-in-china.com/

FIRIP Drill Tools At FIRIP, we pride ourselves on being a leading manufacturer and supplier, dedicated to delivering high-performance DTH hammers and drills.

Our versatile tools excel across various drilling applications, including mining, quarrying, water well drilling, geotechnical engineering, and more.

Bit Face Shape Selection:


1. Drop Center Bit
Ideal for achieving high penetration rates in soft to medium hard and corrosive rock formations, operating under low to medium air pressures. This bit offers exceptional hole deviation control.
2. Concave Face
Designed for all-round applications, this bit face is perfect for medium hard and homogeneous rock formations, providing excellent hole deviation control and efficient flushing capabilities.
3. Convex Face
Optimized for high penetration rates in soft to medium-hard rock formations with low to medium air pressures. Offers superior resistance to steel wash, reducing load and wear on the gauge buttons, although it provides limited hole deviation control.
4. Double Gauge Face
Engineered for rapid penetration rates in medium to hard rock formations, this face shape is designed for high air pressures and offers excellent resistance to steel wash, thanks to the step gauge bit.
5. Flat Face Bit
Perfect for tackling hard to very hard and abrasive rock formations with high air pressures. This face shape ensures good penetration rates and robust resistance to steel wash.
