The Milwaukee® three piece 18 in ship auger bit set drills through upto 2X the nails of competitive auger bits without needing resharpening. Drill into clean or 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, even in deep holes. The polished and coated flute finish means 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. Milwaukee® Wood Drill Bit Set, 3 Piece, Specifications: 18 in L Bit, Alloy Steel
