HARD-HEAD CORE BITS 1-3/4" THRU 3"
Relton’s “Hard-Head" bits are designed to bore large holes through concrete without the need to break out the core every few inches. Slide taper end of shank into the “Hard-Head" bit. A slight twisting motion will help keep the bit from falling off before beginning the cut. The pilot is integrated on the shank, so drilling can be accomplished without interruption! (Once used, shank and head become one-piece.)
