Abstract

The invention relates to a stop for a rotating drilling, milling or countersinking tool which comprises a stop sleeve which is freely rotatably coupled, by means of a sliding or rolling bearing, around the tool. A first bearing bush of the bearing supports the stop sleeve. A second bearing bush of the bearing sits in a rotationally fixed manner on a shaft sleeve. The shaft sleeve can be pushed and fastened on a shaft of the tool. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool having such a stop.

First claim

1 . A stop for a rotary drilling, milling or countersinking tool comprising a stop sleeve coupled in a freely rotatable manner about the tool to a plain or rolling bearing, wherein a first bearing bushing of the bearing carries the stop sleeve, characterized in that a second bearing bushing of the bearing sits in a rotationally fixed manner on a shank sleeve, wherein the shank sleeve can be pushed and fastened on an unthreaded shank of the tool.

2 . The stop according to claim 1 , wherein the shank sleeve can be adhesively bonded, pressed or clamped on the tool shank.

3 . The stop according to claim 1 , wherein the first bearing bushing is adhesively bonded or pressed into the stop sleeve.

4 . The stop according to claim 1 , wherein a lock nut, particularly a knurled nut, is included, which can be screwed on an adjusting thread of the tool shank, and which is designed for countering locking of the shank sleeve.

5 . The stop according to claim 4 , wherein the lock nut comprises a threaded tool shank or a quick-change tool shank.

6 . The stop according to claim 1 , wherein at least one second axially offset bearing is arranged between the stop sleeve and shank sleeve.

7 . The stop according to claim 1 , wherein the shank sleeve comprises at least one, particularly two or more radially acting clamping means, by means of which the shank sleeve can be clamped in a rotationally fixed and axially fixing manner on the tool shank.

8 . The stop according to claim 7 , wherein the clamping means are clamping bolts, particularly Allen bolts, wherein the tool shank preferably comprises radially orientated engagement recesses or fixing threads for a rotationally fixed and axially locking engagement of the fixing screws.

9 . The stop according to claim 7 , wherein the clamping means are clamping means, and particularly comprise a clamping ring or a clamping collar, as a result of which the adjusting sleeve can be fixed in a clamping manner on the tool shank.

10 . The stop according to claim 1 , characterized in that one or more adapter bushings are included, which can be plugged into the adjusting sleeve, in order to adapt the internal diameter thereof to an external diameter of a tool shank.

11 . The stop according to claim 1 , characterized in that a bearing clamping bolt arranged on a bearing clamping thread of the shank sleeve, so that a bearing play of the bearing can be set.

12 . A drilling, milling or countersinking tool with a stop, wherein a stop according to one of the preceding claims is fastened on the tool shank.
