Product Description
Milwaukee Flat Boring Bit 1/2 in. x 6 in.
Model Number: 48-27-0501
The Milwaukee 48-27-0501 is a 1/2 in. x 6 in. Flat Boring Bit for drilling clean, precise holes through framing lumber, dimensional wood, plywood, OSB, and wood composites for electrical rough-in, low-voltage cabling, plumbing, and general construction applications where the 1/2 in. bore provides the correct clearance for small flexible conduit, smaller NM cable runs, specific plumbing applications, and fastener holes that require exactly a 1/2 in. through-bore in wood structural elements. The flat boring geometry produces holes with flat bottoms, smooth cylindrical sidewalls, and clean entry and exit faces with minimal splintering — a fundamentally better hole quality for wood compared to twist bit drilling because the flat boring bit's outer spur scores the perimeter before the cutting face shears the enclosed wood fiber, preventing the surface tear-out that drill exits in wood produce with twist bits. This superior entry and exit face quality is important when drilling through finished surfaces or in locations where hole edge appearance is visible in the finished installation.
Made from heat-treated high carbon steel, Milwaukee's flat boring bit maintains cutting edge sharpness through the sustained drilling demands of commercial rough-in projects where hundreds of holes per day are required for completion within project schedule. A precision-ground self-centering tip establishes the hole at the exact marked center location and prevents bit walking before the cutting face engages — important for hole position accuracy in fire-rated assemblies and layout-specified locations where the hole center must match the installation drawing dimensions. The standard 6 in. length handles single-member framing dimensions in typical stud, joist, and rafter construction. Milwaukee's flat boring bit lineup covers 1/4 in. through 1-1/2 in. in both 6 in. and 16 in. lengths.
Available in 16 in. extended length for multi-member and built-up structural drilling — see Milwaukee's complete flat boring bit range for all available diameters and lengths.
