A cutting tool having a shank and a cutting head, wherein the shank carries a depth stop, which limits penetration depth into a workpiece, via at least one pivot bearing, and the depth stop is spring-preloaded away from the cutting head, via the at least one pivot bearing, against a shank-side stop.

Cutting tool having a depth stop

A stop for a rotating drilling, milling or countersinking tool comprising a stop sleeve coupled to a radial rolling bearing in such a way that it freely rotates about the tool, an outer bearing bush of the radial rolling bearing being attached to the stop sleeve and an inner bearing bush of the radial rolling bearing being attached to a shaft sleeve that can be attached to a tool shaft of the tool. An axial rolling bearing is also provided, a housing washer of the axial rolling bearing being supported on the stop sleeve and a shaft washer of the axial rolling bearing being supported on the shaft sleeve. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool provided with such a stop.

Stop for a drilling, milling or countersinking tool

A rotary tool, comprising: a tool main body comprising a clamping section and a tool head; an exchangeable first cutting insert having at least one first cutting region having a first cutting edge, wherein the first cutting insert can be inserted into an insert groove of the tool main body from the front side of the tool head and can be fastened therein in a rotationally fixed manner; and an exchangeable second cutting insert fastened to the tool head and offset toward the clamping section in the axial direction of the rotary tool relative to the first cutting insert and which has an insert main body and at least one second cutting region having at least one second cutting edge. A fastening means for the second cutting insert is arranged in the insert groove of the first cutting insert. Also, a cutting insert set and a tool main-body set.

Rotary tool having exchangeable cutting inserts and tool main-body set for a rotary tool

An orienting apparatus for arranging on a turning tool and for orienting a bore or depression to be introduced or for orienting a finishing step with respect to a normal to the surface of a workpiece, comprising a main body having a through-hole for receiving the tool shank or the tool tip in an orienting direction, and at least two probe elements for oriented support on the surface of the workpiece. As a result of an orienting movement of the orienting apparatus with respect to the normal to the surface of the workpiece, all of the probe elements form an electric circuit between an electrical current source contained in the main body and the signaling device, said electric circuit being closed by a series circuit activated by the probe elements. Furthermore, a method for orienting a bore or depression or for orienting a finishing step with an orienting apparatus.

Orienting apparatus for turning tools

A tool alignment device for mounting on a tool having a stop, especially on a drilling and/or countersinking tool having a single-piece tool shaft and a stop, for alignment of a drill hole and/or countersink to be introduced or for alignment of a finishing step in relation to a normal to the surface of a workpiece, comprising a main part and a through hole. Upon mechanical contact between the tool alignment device and the surface of the workpiece, a signaling device is actuated and emits alignment signal(s) during alignment in an alignment direction, and the stop of the tool can be accommodated in the main part, which comprises a guide device which establishes a connection between a stop sleeve of the stop and the tool alignment device such that the stop can be aligned in the alignment direction. Also, a drilling, milling and/or countersinking tool having a stop.

Tool alignment device

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.
