Rotatable tool has combined catch element for limiting penetration depth of tool in work piece, where coupling between catch element and tool is free from torque-transferring connection

摘要

The rotatable tool (3) has a combined catch element (1) for limiting the penetration depth of the tool in a work piece. The coupling (7) between the catch element and the tool is free from a torque-transferring connection. The coupling comprises a connection (8) working in a form-fit manner in the direction of the longitudinal axis (L-3) of the tool describing the rotation axis (R).
