Abstract
A rotating tool includes a circumferential surface formed with a tool anchorage arrangement. The tool anchorage arrangement follows a stepped path. The tool anchorage arrangement includes an entry recess and, subsequent thereto, a radial recess and, subsequent thereto, an axial recess. Additional radial and axial recesses may be alternated to increase the number of steps, thereby extending the length of the stepped path.
Claims18
A rotating tool having a tool axis defining opposite tool forward and backward directions and opposite tool rotation and reverse-rotation directions, the rotating tool comprising:
- a rear end;
- a front end located forward of the rear end;
- and
- a circumferential surface extending forward of the rear end;
- the circumferential surface being formed with a tool anchorage arrangement;
- the tool anchorage arrangement following a stepped path, the stepped path comprising:
- an entry recess extending forward from the rear end;
- a radial recess intersecting, and extending in the tool rotation direction from, the entry recess;
- an axial recess intersecting, and extending forward from, the radial recess;
- an additional radial recess intersecting, and extending in the tool rotation direction from, the axial recess, the additional radial recess being axially forward of the radial recess, along the tool axis;
- and
- an additional axial recess intersecting, and extending forward from, the additional radial recess.
