Milwaukee's precision machined 1-1/2 inch Ship Auger Bit provides smooth, wobble free deep hole boring. The wide throat design gives excellent chip clearance. The self feeding screwpoint and single cutting edge result in fast rough boring in wood. A hardened cutting edge means less frequent need for re-sharpening. The shank of the bit is 1/2 inch for use in 1/2 inch and larger drills. Drilling depth is 6 inches. One per package.
