Abstract
A tool bit having a shank having a hexagonal cross-section adapted to be removably positioned within a tool for rotating the shank, a first circular section extending from a first end of the shank, an exposed circumferential groove positioned adjacent the first circular section, a second circular section having an outer surface extending from the circumferential groove, a first bit end extending from the second circular section, wherein a right angle is formed at the transition of the circumferential groove to the outer surface of the second circular section forming a first transverse gripping wall that is perpendicular to a longitudinal axis of the shank.

A tool bit comprising:
- a shank having a hexagonal cross-section adapted to be removably positioned within a tool for rotating the shank, the shank having a thickness D1;
- a first circular section extending from a first end of the shank, the first circular section having a diameter D2, where D2 is less than D1;
- an exposed circumferential groove positioned adjacent the first circular section, where the exposed circumferential groove has a diameter D3 which is less than diameter D2;
- a second circular section having an outer surface extending from the circumferential groove;
- a first bit end extending from the second circular section;
- and
- wherein a right angle is formed at the transition of the circumferential groove to the outer surface of the second circular section forming a first transverse gripping wall that is perpendicular to a longitudinal axis of the shank.
