<p>The aim of the invention is to improve the guiding of a lubricant through a tool holder in a small quantity lubrication system. According to the invention, a tool holder ( 1 ) comprises, in the maintaining body thereof ( 3 ), an axially displaceable stop sleeve ( 45 ) which is mounted in a through opening ( 31 ) which is connected to the receiving opening ( 13 ) for a tool shaft ( 15 ) and a stop surface ( 47 ) which is adjacent to the front end ( 23 ) of the tool shaft ( 15 ). Said stop sleeve ( 45 ) is screwed into an inner thread ( 43 ) of the through opening ( 31 ) and is coupled in a rotationally fixed manner, but in an axially displaceable manner, to a control tube ( 49 ) which engages in said stop sleeve ( 45 ) in an axial manner. Said control tube ( 49 ) is mounted in an axially fixed manner to the side thereof, but in a rotatable manner to the fluid coupling ( 27 ). A lubricant can be guided over the blades of the tool ( 9 ) by means of the fluid coupling ( 27 ), the control tube ( 49 ), the stop sleeve ( 45 ) and channels ( 17 ). Said tool holder ( 1 ) enables the fluid to be guided in an essentially calm manner to the tool, even in small amounts, and simplifies the longitudinal pre-adjustment of the tool unit/tool holder unit.</p> |
