Built on a high-speed steel body with a 5\/16-inch diameter and a three-flat shank, this bit delivers reliable grip in SDS-style and keyed hammer drill chucks. It features an 8-inch flute length and a 10-inch overall length, giving tradespeople the reach needed for through-hole applications in block, brick, and concrete. The two-flute, percussion-ground cutting geometry clears debris efficiently during rotary hammer operation. Electricians, HVAC installers, and plumbers use bits like this when anchoring equipment or running conduit through masonry substrates.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for residential and light commercial masonry drilling tasks. Typical applications include setting anchor bolts, drilling penetrations for conduit or pipe sleeves, and boring through concrete block or brick during rough-in work. The 5\/16-inch diameter is a common size for drop-in anchors and sleeve anchors used in mechanical and electrical trades. The three-flat shank design prevents slipping in compatible hammer drill chucks and is a standard configuration across rotary hammer accessories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edge for extended service life in masonry\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch drill diameter and matching shank diameter for consistent fit\u003c\/li\u003e\n  \u003cli\u003e8-inch flute length promotes effective debris evacuation during drilling\u003c\/li\u003e\n  \u003cli\u003e10-inch overall length provides reach for through-wall and deep anchor applications\u003c\/li\u003e\n  \u003cli\u003eThree-flat shank resists rotation and seats securely in compatible chucks\u003c\/li\u003e\n  \u003cli\u003ePercussion cutting shape optimized for rotary hammer operation in block, brick, and concrete\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement bit for use in rotary hammer drills and hammer drills that accept a three-flat shank configuration.
