Abstract

The proposed polishing tool has a base body with an open interior space with which the polishing tool can be slidably fitted onto a holder of a tool spindle, initially as far as a latching position. A retaining ring placed in an annular groove of the interior space engages in a counter-groove of the holder. The polishing tool can then be slid further onto the holder under the polishing work pressure, until, under the simultaneous action of torque, driver elements of the base body engage in driver counter-elements of the holder for transmitting rotary movement. At least in the latter relative position between the polishing tool and tool spindle, the retaining ring provides a seal against penetration of the abrasive polishing agent.
