摘要:
The invention relates to a stop (12) for a rotating drilling, milling or countersinking tool (10) which comprises a stop sleeve (16) which is freely rotatably coupled, by means of a sliding or rolling bearing (14), around the tool (10). A first bearing bush (18) of the bearing (14) supports the stop sleeve (16). A second bearing bush (20) of the bearing (14) sits in a rotationally fixed manner on a shaft sleeve (22). The shaft sleeve (22) can be pushed and fastened on a shaft (28) of the tool (10). In a secondary aspect, the invention relates to a drilling, milling or countersinking tool (10) having such a stop (12).
摘要:
The invention relates to an exchangeable stop (12) for a rotating drilling, milling or countersinking tool (10). The stop comprises a stop sleeve (16) that is coupled to a plain bearing or roller bearing (14) so as to be freely rotatable about the tool (10), wherein a first bearing bush (18) of the bearing (14) carries the stop sleeve (16) and a second bearing bush (20) of the bearing (14) is fitted on an adjusting ring (22) for conjoint rotation. The adjusting ring is axially adjustable with respect to an adjusting sleeve (24) or a shank (28) of the tool (10) by means of an adjusting thread (26) attached to the outer circumference of the adjusting sleeve (24) or an adjusting thread (26) attached to the tool shank (28). The adjusting sleeve (24) is fastenable in an exchangeable manner on a shank (28) of the tool (10) for conjoint rotation, or the adjusting ring (22) is mounted or screwed in an exchangeable manner onto the adjusting thread (26) of the tool (10).
