Product Description
Milwaukee 1-1/4 in. x 6-1/2 in. Auger Bit
Model Number: 48-13-1250
The Milwaukee 48-13-1250 is a 1-1/4 in. x 6-1/2 in. Auger Bit for drilling large-diameter, clean holes through framing lumber, dimensional wood, engineered wood products, and nail-embedded wood in plumbing rough-in, HVAC, and electrical rough-in applications where the 1-1/4 in. diameter provides the correct bore for large-diameter plumbing drain and vent pipes, 1 in. rigid conduit penetrations, and structural bolt holes in heavy timber assemblies. The 1-1/4 in. is among the largest standard ship auger sizes, delivering the bore capacity for the largest plumbing and conduit penetrations through wood framing that require a self-feed auger rather than a hole saw. The self-feed screw tip automatically pulls the bit into the wood under its own rotational force, eliminating the heavy manual downward pressure that fatigues operators in sustained large-bore drilling. Milwaukee's through-center cutting design provides improved durability when the bit encounters embedded nails and fasteners during retrofit drilling in existing wood structures.
Non-stick coated flutes maintain fast, continuous chip ejection throughout the bore depth at this large diameter — at 1-1/4 in., the volume of wood chips generated per revolution is substantial, and effective flute chip transport is essential for maintaining drilling speed and preventing binding from accumulated chips in the flute channels. The 6-1/2 in. working length handles standard single-member framing penetrations in typical joists, studs, and rafters while providing the depth needed for thicker-than-standard framing members and built-up sections where the 6 in. flat boring bit length falls marginally short. The combination of large bore capacity, self-feed advance, and through-center nail tolerance makes this bit a core tool for plumbers and HVAC installers who drill large-diameter rough-in holes through wood framing at production pace on commercial and residential projects.
Available in 18 in. length for deep multi-member drilling — see Milwaukee's complete ship auger and flat boring bit lineup for all available diameters and lengths.
