Drill Bit Adaptor

Brief Introduction:

With a drill bit adapter, the same drill bit can be used with different self drilling rock anchors, and meanwhile the same self drilling rock anchors can drill different holes.

Application:

To avoid excessive deflection in the drilling process, our suggestion is choosing drill bits which is one size up. For example, R32 self drilling rock anchor can be adapted to a R38 drill bit.

Feature:

Stopper is added according to construction requirement,which is added at one end of drill bit which makes convenient application. If there is no stopper, the self drilling rock anchors may rotate and penetrate drill bit adapter easily to shorten the contacting length of drill bit adapter and drill bit.
