Milwaukee's ship auger bits have a new through center cutting design for improved life in nail-embedded wood. The flutes are coated, which produces a non-stick surface for fast and smooth chip ejection, especially in deep holes. The shanks are also impact rated for added durability and versatility no matter the trade. Ideal for electricians, plumbers, utilities and any trade requiring fast hole drilling in clean or nail-embedded wood. Includes induction hardened tip for added nail durability.
