Quick-change insert for tools, especially for thread drills

摘要

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.
