A hammer drill bit that walks on the first touch, burns out in brick, or walks off concrete costs more in redrilling than a fresh bit is worth. This 8" SDS-Plus hammer drill bit in 1/4" diameter is built for the specific tolerances of SDS-Plus rotary hammers — it self-starts without chasing and drills straight through concrete, block, and brick without walking. The 8" length handles standard lumber depths plus the masonry substrate underneath. DeWalt makes the bits that framers and masons reach for on every pour because they hold up to the abuse of real job-site use.
