Milwaukee® THUNDERBOLT® pilot bits are designed for extreme durability and long life. The THUNDERBOLT® web features a thicker core than a standard pilot bit, which provides ultimate strength and protects against side-load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. A precision start, 135º split point tip starts on contact to keep the bit from walking for fast, accurate holes. Excellent for drilling on curved surfaces, requires less effort to drill and is highly recommended for use with portable drills.

The Milwaukee® 9/16 in. x 18 in. Ship auger bit drills through up to 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.
