The rock drilling speed is fast and easy to grind.
Taper joints and threaded ball teeth of different diameters are widely used in all kinds of hard and brittle rocks to match rock drilling. Compared with the traditional sheet-shaped bit, the cylindrical bit has the characteristics of long grinding period and fast drilling speed.
