Bit Face Shape Selection:
Center Drop Bit:
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressure.
Maximum hole deviation control.
Concave Face
The all-around application bit face specifically for medium hard and homogeneous rock formations.
Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash and may reduce the load and wear on gauge buttons, but poor hole deviation control.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressure and good resistance to steel wash step gauge bit.
Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formation is applications with high air pressure. Good penetration rates and resistance to steel wash.
Competitive Advantage
• High-grade tungsten carbide inserts
• Bit bodies manufactured from high-grade steel and processed using
state-of-the-art CNC machinery and heat treatment
Applications
• Underground mining
• Down the hole rock drilling
