DEWALT's 5/8 in. x 10 in. x 12 in. SDS-Plus Rock Carbide Hammer Bit provides a 5/8 in. drilling diameter, 10 in. flute and usable drilling length, and 12 in. overall length for applications requiring extended reach. Its carbide-tipped construction is engineered for longer bit life, while the four-flute configuration assists with rapid debris removal as the hole develops. Increased steel in the body helps resist breakage, and the bit's SDS-Plus shank provides a secure fit in compatible rotary hammers. A wear-mark indicator helps identify when the cutting diameter may no longer be suitable for accurate anchor-hole installation, making it useful for tradespeople who need predictable hole sizing on concrete and masonry jobs.
