Rotating bit with integral washer feature

Abstract

A bit including a bit body and a shank depending from a bottom of the bit body. The bit body including an integral washer portion that extends to a rear annular flange and a tapered portion adjacent the rear annular flange that is complementary to an angle of a countersink at a forward end of a bore of a bit holder, radially aligning the bit concentric with the bore of the bit holder. The shank comprises a cap distal portion including a diameter that is less than or equal to a diameter of a forward portion of the shank. The bit includes a retainer disposed circumferentially about the shank, the retainer including a reduced diameter distal section allowing the bit to be manually inserted into the bore of the bit holder a predetermined distance before needing to resort to hammer hits to securely mount the bit in the bore of the bit holder while still allowing the bit to freely rotate within the bore of the bit holder.
