Spherical Button Drill Bit

Spherical button drill bit is the most common rock drilling bit. Under the condition of sufficient impact power of the hydraulic rock drill, the spherical drill bit has high energy efficiency. Compared with other carbide shapes, the spherical carbide button is stronger and more wear-resistant, and the rock breaking effect is better. 

Our R32 spherical button drill bits provide excellent penetration performance, whether in medium-hard rock, hard rock, or other types of rock.
