Abstract

See full text

A percussive rock drill bit includes a head provided at one end of a rearwardly projecting skirt. The head has an outer collar that defines, in part, a rearwardly projecting recess formed in the forwardmost region of the head. Peripheral gauge buttons are provided at the collar to surround side and front facing buttons formed at the head recess. The drill bit is effective to provide stabilised cutting to minimise lateral deflection.
