Product Description
Milwaukee Flat Boring Bit 9/16 in. x 6 in.
Model Number: 48-27-0561
The Milwaukee 48-27-0561 is a 9/16 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 rough-in, plumbing, low-voltage cabling, and general construction applications where the 9/16 in. diameter is the correct bore size for the material being routed. The 9/16 in. bore accommodates smaller flexible conduit, low-voltage cable bundles, and specific fastener and bolt sizes that require the precise 9/16 in. hole diameter rather than an adjacent standard size — it sits between the commonly stocked 1/2 in. and 5/8 in. sizes to fill the dimensional gap for applications where those adjacent sizes are too small or too large. Made from heat-treated high carbon steel, the bit bores clean holes with the sustained edge sharpness needed for high-volume production rough-in drilling without requiring frequent replacement or sharpening interruptions during active project work.
The flat boring bit geometry uses a sharp outer spur and a flat, sharp-edged cutting face that shears wood fiber cleanly on both entry and exit faces, producing smooth, well-defined holes with minimal splintering that meet inspection standards for visible rough-in locations and reduce fiber interference during cable and conduit routing through the hole opening. A precision-ground self-centering tip starts the bit at the exact marked center point and maintains bit position before the cutting face engages, preventing walking on smooth wood grain and end-grain cut surfaces. The 6 in. length fits standard single-member framing dimensions and provides adequate depth for the tight inter-member clearances encountered during rough-in work from below joists and inside wall cavities.
Available in 16 in. extended length for deep drilling requirements — 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 coverage.
