Product Description
Milwaukee Flat Boring Bit 7/8 in. x 6 in.
Model Number: 48-27-0871
The Milwaukee 48-27-0871 is a 7/8 in. x 6 in. Flat Boring Bit for drilling clean, accurately-sized holes through framing lumber, dimensional wood, plywood, OSB, and wood composites for electrical, plumbing, and mechanical rough-in applications in wood-frame construction. The 7/8 in. diameter provides a bore size appropriate for larger NM cable bundles, 3/4 in. flexible conduit, medium-diameter plumbing rough-in holes, and structural bolt holes where the 3/4 in. standard hole size is slightly too small for clearance. Made from heat-treated high carbon steel, the Milwaukee flat boring bit bores clean holes with the sustained cutting edge sharpness needed to maintain hole quality and cutting speed through the high volume of holes that characterizes production rough-in work without frequent sharpening interruptions that reduce job productivity.
The flat boring bit's cutting geometry uses a sharp outer spur to score the hole perimeter and a flat, sharp-edged cutting face to shear wood fiber from the interior, producing smooth, well-defined hole walls with minimal splintering on both entry and exit faces of the workpiece. Clean hole edges at 7/8 in. reduce fiber interference during cable and conduit routing through the hole and produce a professional result that passes inspection in visible rough-in locations. A precision-ground self-centering point starts the bit at the exact marked location and maintains bit position before the cutting face engages, preventing bit walking during hole engagement on smooth grain surfaces and end-grain cuts where conventional bits drift from the marked center. The 6 in. length handles single-member framing in standard stud, joist, and rafter dimensions while fitting the confined clearances inside wall and floor assemblies during rough-in work.
Available in 16 in. extended length for deep drilling through double members, built-up beams, and multi-layer structural sections — Milwaukee's flat boring bit range covers 1/4 in. through 1-1/2 in. diameter in both 6 in. and 16 in. lengths for complete rough-in bit coverage.
