The MILWAUKEE 1-1/16" x 150mm Ship Auger Bit drills through up to 2X the nails of competitive auger bits without needing resharpening. Drill into nail-embedded wood with confidence when installing Romex wire, Pex water lines, rebar, bolts, and rope in piers, playground equipment and landscaping. The flutes are wider for maximum chip removal and polished and coated so chips won't stick to the bit, even when drilling in material that contains sap or glue.The through-center cutting design creates a more solid striking point against nails compared to the competitions' ahead-of-center and behind-center designs. The longer shaft length makes it easy to drill deeper or overhead without an extension.
