Sold as a 2-count pack, each bit measures 11\/16 inches in diameter with a 16-inch working length, giving tradespeople the reach needed for deeper anchor and pass-through holes. The spline drive interface transfers torque and impact energy efficiently from the rotary hammer to the bit, reducing operator fatigue and improving hole quality. This bit is a standard tool for electricians, plumbers, HVAC techs, and general contractors who core through concrete floors, block walls, or slabs on a regular basis.\u003c\/p\u003e\u003cp\u003eThis bit is suited for residential and commercial applications where a spline-drive rotary hammer is already in use. Common tasks include drilling anchor holes, conduit pass-throughs, pipe sleeve penetrations, and equipment mounting points in poured concrete or CMU block. The 16-inch length provides clearance in tight framing bays or stacked block conditions. The 2-count pack supports jobsite continuity when one bit is down for sharpening or replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/16-inch diameter for standard anchor and sleeve-fit hole sizes\u003c\/li\u003e\n\u003cli\u003e16-inch overall length for deep-reach penetrations through thick slabs or block\u003c\/li\u003e\n\u003cli\u003eSpline drive shank for compatibility with spline-drive rotary hammers\u003c\/li\u003e\n\u003cli\u003e2-count pack included per unit sold\u003c\/li\u003e\n\u003cli\u003eDesigned for use in concrete, masonry, and CMU block\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with spline-drive rotary hammers; verify your hammer accepts a spline-drive chuck or adapter before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified tradespeople familiar with rotary hammer operation and applicable safety codes.
