Product Description
Milwaukee Flat Boring Bit 1 in. x 16 in.
Model Number: 48-27-0195
The Milwaukee 48-27-0195 is a 1 in. x 16 in. Flat Boring Bit — the extended-length version of the 1 in. flat boring bit for deep drilling through multiple framing members, built-up structural sections, and thick wood assemblies where the standard 6 in. length cannot reach the required hole depth from a single drill position. The 16 in. length allows electricians, plumbers, and HVAC installers to complete full-depth holes through double top plates, built-up beams, deep floor system assemblies, and multi-layer structural wood sections in commercial wood-frame construction in a single drill setup without repositioning, re-aligning, or connecting extension bits. The 1 in. diameter provides the correct bore for 3/4 in. EMT and IMC conduit, 3/4 in. flexible conduit, medium-diameter plumbing rough-in pipe, and specific HVAC rough-in penetrations — one of the most heavily drilled sizes in commercial electrical and plumbing rough-in work.
Made from heat-treated high carbon steel, Milwaukee's flat boring bit provides the sustained cutting edge sharpness needed for the high volume of 1 in. holes drilled during a full commercial rough-in project. The flat boring geometry uses a sharp outer spur to score the hole perimeter and a flat cutting face to shear wood fiber cleanly on both entry and exit faces with minimal splintering — important for producing the clean hole profiles that firestop systems and bushing installations require at penetration points. A self-centering tip prevents bit walking on smooth wood grain and end-grain surfaces, maintaining the accurate hole position that is critical in fire-rated assemblies where the opening size and location are specified by firestop installation drawings. The 16 in. length provides adequate working depth for the deepest multi-member framing assemblies encountered in commercial construction, eliminating the drill repositioning and bit changes that would otherwise interrupt production drilling pace.
Available in standard 6 in. length for single-member drilling — Milwaukee's flat boring bit range covers 1/4 in. through 1-1/2 in. diameter in both 6 in. and 16 in. lengths.
