ABSTRACT:
The power tool has a spindle lock member rotating with the output spindle with a blocking member normally rotating with the lock member but capable of being restrained against rotation. The blocking member extends beyond the lock member and is provided with an opening through which the lock pin can project if the blocking member is at rest or rotating slowly but the opening precludes lock pin entry at normal operation speeds. The lock member has a recess of substantial angular embrace so the ends of the recess can be impacted on the lock pin.
