Product Description
Milwaukee 1-1/8 in. x 18 in. Ship Auger Bit
Model Number: 48-13-6120
The Milwaukee 48-13-6120 is a 1-1/8 in. x 18 in. Ship Auger Bit for drilling large-diameter, deep-reach holes through framing lumber, structural timber, and nail-embedded wood in plumbing, HVAC, and electrical rough-in applications where the 1-1/8 in. bore provides the clearance for specific large-diameter conduit, pipe, and structural applications requiring this precise bore size between the common 1 in. and 1-1/4 in. adjacent specifications. The 1-1/8 in. diameter is used for specific conduit fitting systems, large-diameter flexible conduit, structural bolt holes in timber-frame assemblies, and plumbing rough-in where the 1-1/8 in. bore specification is called out for the pipe or fitting system being installed. The self-feed screw tip advances the bit through wood automatically under its own rotational force, and Milwaukee's through-center cutting design provides improved durability in nail-embedded retrofit conditions where embedded fasteners are encountered during drilling.
The 18 in. working length provides the deep reach required for drilling through multiple stacked framing members, double top plates, deep floor system assemblies, and thick timber sections that the standard 6 in. length cannot penetrate from a single drill position. Non-stick coated flutes maintain fast, continuous chip ejection from the full 18 in. bore depth — at 1-1/8 in. diameter, the volume of wood chips generated per revolution is substantial, and effective flute action throughout the full 18 in. depth is critical for maintaining drilling speed without chip packing. The 18 in. length makes this bit the right tool for multi-member rough-in applications in commercial construction where single-story framing assemblies with double plates and thick floor systems routinely exceed the depth capacity of standard auger lengths.
Available in 6 in. standard length — Milwaukee ship auger bits cover 3/8 in. through 1-1/2 in. in both 6 in. and 18 in. configurations.
