Abstract

A drilling tool (10) incorporating first and second ends, a shaft (13, 90) extending between the ends. The first end has a drill bit (15) to penetrate rock. The drill bit and the shaft have complementary threads. The drill bit and the shaft comprise a relative rotation stop means (82, 83) that ensures that the drill bit remains loose during drilling in a first direction. The invention further relates to a self drilling rock bolt (10), a drill bit (15), drill shaft (13,90) and shaft coupling (94), an anchoring device (23), and an end coupling (95) per se.
