375225 Rawl Tapper Carbide Masonry Drill Bit, 3/16 X 5.5-in.

The Hillman 375225 Rawl Tapper Carbide Masonry Drill Bit is a precision tool engineered for drilling accurate pilot holes in concrete, brick, and stone. This carbide-tipped bit is specifically designed to work with Rawl tapper concrete screws, which use the pilot hole to tap threads directly into hard substrates. The tapered shank geometry maximizes torque transfer and ensures proper alignment with matching tapper fasteners, delivering clean and precise holes every time.

Carbide-tipped drill bits excel where standard steel bits fail, maintaining their cutting edge through demanding masonry applications with minimal wear. Whether you're anchoring fixtures, installing hardware, or preparing surfaces for fastening, this bit provides the durability and accuracy needed for professional results. The compact 5.5-inch length offers excellent control in tight spaces, making it ideal for both experienced contractors and DIY enthusiasts working on masonry projects.
