Product Description
Milwaukee 7/8 in. x 16 in. Flat Boring Bit
Model Number: 48-27-0190
The Milwaukee 48-27-0190 is a 7/8 in. x 16 in. Flat Boring Bit — an extended-length boring bit for drilling through multiple stacked framing members at the 7/8 in. bore diameter for conduit fittings, flexible conduit systems, and installations requiring this specific bore between the adjacent 3/4 in. and 1 in. standard sizes. The 16 in. working length provides the reach for drilling through double top plates, multiple joists, built-up headers, and other multi-member assemblies where the standard 6 in. configuration cannot penetrate the complete depth from a single drill position. The flat boring geometry produces clean-sided cylindrical holes with flat bottoms and surface tear-out prevention from the outer spur scoring the perimeter ahead of the flat cutting face — providing professional-quality entry and exit hole faces even through the full 16 in. depth of multi-member assemblies.
Heat-treated high carbon steel maintains the cutting edge sharpness for clean, consistent 7/8 in. holes through the high drilling volume of commercial rough-in work where many holes at this diameter are required for completing installation scope on schedule. The self-centering tip establishes the correct hole position at each framing member face without bit walking during initial contact, maintaining the alignment through the full multi-member depth. At 16 in. length, the flat boring bit handles the full depth of commercial multi-member framing assemblies that are standard in commercial construction but impractical to drill from two sides — the single-pass capability from one accessible face position saves significant setup time compared to two-sided drilling approaches.
Available in 6 in. standard length for single-member drilling — Milwaukee's flat boring bit range covers 1/4 in. through 1-1/2 in. in both configurations.
