Key Features
Unwavering quality with extended service life and minimal instances of abnormal breakage during usage
Superior flushing efficacy ensuring enhanced drilling speeds
Comprehensive quality assurance and compensation policies
Choosing the Right Bit Face Shape
Drop Center Bit: Ideal for achieving high penetration rates in soft to medium-hard, fissured rock formations under low to medium air pressures. Ensures maximum control over hole deviation.
Concave Face: A versatile bit face designed specifically for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and superior flushing capability.
Convex Face: Perfect for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Notable for its resistance to steel wash and reduced load and wear on gauge buttons; however, it offers lesser control over hole deviation.
Flat Face: This face shape is tailored for hard to very hard, abrasive rock formations, performing exceptionally well under high air pressures. Delivers robust penetration rates and resistance to steel wash.
