DEWALT's 1/4 in. x 2 in. x 4 in. SDS-Plus 2 Cutter Drill Bit provides a 2 in. usable drilling depth and 4 in. overall length for common concrete and masonry fastening work. The four-flute body promotes efficient debris removal, while the SDS-Plus shank provides a secure fit in compatible rotary hammers.
