ABSTRACT:
The present invention relates to a quick-change insert (10) for tools (11), in particular thread drills (12), for minimal lubrication, that is designed for detachable installation in a chuck (30) provided with a central lubricant channel (32) and for introducing the lubricant as an aerosol from the lubricant channel (32) into the rear end of a longitudinal bore (14) of an inserted tool (11). A sealing body (40) provided with a central passage (41) is located in a rear receptacle (25) of the insert body (17) such that, when the tool (11) is inserted and installed in the chuck (30), it connects the lubricant channel (32) and the longitudinal bore (14) of the tool (11) with each other in an at least substantially leakproof manner.
