Product Description
Milwaukee 1-3/8 in. x 18 in. Ship Auger Bit
Model Number: 48-13-6370
The Milwaukee 48-13-6370 is a 1-3/8 in. x 18 in. Ship Auger Bit for drilling deep holes through framing lumber, dimensional wood, and nail-embedded wood in plumbing, HVAC, and electrical rough-in applications where the 1-3/8 in. bore and 18 in. working length are both required for the specific penetration through multiple stacked framing members or deep structural assemblies. The 1-3/8 in. diameter serves specific flexible conduit systems, large wire bundle routing, and plumbing rough-in applications where neither the 1-1/4 in. nor the 1-1/2 in. adjacent sizes provide the correct bore for the fitting or conduit system being installed. The self-feed screw tip automatically advances the bit through wood under its own rotational force, and Milwaukee's through-center cutting design provides improved durability in nail-embedded retrofit and remodel drilling conditions where embedded fasteners are regularly encountered.
The 18 in. working length provides the deep reach required for drilling through multiple stacked framing members, double top plates, built-up beams, and thick timber sections in commercial construction where the standard 6-1/2 in. configuration cannot penetrate the full assembly depth from a single drill position. Non-stick coated flutes maintain fast chip ejection from the full 18 in. bore depth at this large diameter where the chip volume per revolution requires effective continuous flute action throughout the full depth to prevent progressive chip packing that slows drilling speed. Available in 6-1/2 in. standard length for single-member drilling — Milwaukee's ship auger range covers 3/8 in. through 1-1/2 in. in both configurations.
