SOLID-BODY "HARD-HEAD" BITS

Relton "Hard-Head" bits are designed to bore large holes through concrete without the need to break out the core every few inches.

Slide the taper end of the shank into the "Hard-Head" bit.  A slight twisting motion will connect the bit and shank before beginning the cut.  The pilot is integrated into the shank, so drilling can be accomplished uninterrupted.  Once used, the shank and head become one piece.
