Product Description
Milwaukee 1-3/8 in. x 6 in. Ship Auger Bit
Model Number: 48-13-1373
The Milwaukee 48-13-1373 is a 1-3/8 in. x 6 in. Ship Auger Bit for drilling large-bore, clean holes through framing lumber, dimensional wood, engineered wood products, and nail-embedded wood for plumbing, HVAC, and electrical rough-in applications where the 1-3/8 in. bore provides the correct clearance for larger-diameter conduit, pipe, and structural penetrations. The 1-3/8 in. diameter accommodates 1 in. EMT and IMC conduit penetrations, larger plumbing rough-in pipe holes, and structural bolt holes where the opening must match the 1-3/8 in. specification — sitting between the common 1-1/4 in. and 1-1/2 in. adjacent sizes to serve the specific bore requirements for fittings, conduit connectors, and pipe dimensions that call for this exact diameter. The self-feed screw tip automatically advances the auger bit through wood under its own rotational force, eliminating the heavy manual drill pressure that fatigues operators during large-bore drilling in production rough-in work.
Milwaukee's through-center cutting design provides improved bit life in nail-embedded wood conditions — the geometry distributes the impact more symmetrically when the 1-3/8 in. bit contacts embedded nails and fasteners in existing framing, preventing the asymmetric tip failure that conventional auger designs experience at large diameters in retrofit drilling. Non-stick coated flutes ensure fast, continuous chip ejection from the bore during drilling at this large diameter where the volume of wood chips generated per revolution is substantial and effective flute evacuation is critical for maintaining drilling speed without binding. The 6 in. working length handles standard single-member framing penetrations across standard stud, joist, and rafter sizes encountered in residential and commercial wood-frame construction.
Available in 18 in. length for deep multi-member drilling applications — Milwaukee's ship auger bit range covers 3/8 in. through 1-1/2 in. diameter in both 6 in. and 18 in. configurations.
