Bit engaging tool, has bit including shank that defines recess for receiving ridge when shank is inserted into space of controller through axial space of socket for locking bit to handle

摘要

The tool has a handle comprising a socket (13) defining an axial non-circular space and a radial space in communication with the axial space. A controller (30) defines a space, where a ridge is formed on the wall of the space, and the controller is movable in the radial space of socket between a locking position and a releasing position. A bit includes a working tip and a shank defining a recess for receiving the ridge when the shank is inserted into the controller space through the axial space of the socket to lock the bit to the handle.
