Roller Bit Cutting Roller RM-SR 260 used for full face roller

Full face roller bit drill heads are used

in very hard rock formations with

strengths  100 MPa.

They make drilling through rock in a

single drilling cycle possible without time

consuming and costly tool changes. The

rock cuttings are usually conveyed by the

air-lift technique into a collector box

mounted on top of the drill head. After

having drilled to a certain depth, the full

face drill head is retracted and the

collector box is emptied.
