摘要： A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. It has a coupling pin onto which outer cover surfaces and torque surfaces are formed as clamping surfaces. The coupling pin has a particular circular groove, which divides the cutting head into a front pin part and a rear pin part. Stop surfaces for an axial pullout safety are formed in the transition area between the two parts. The torque surfaces and the clamping surfaces are arranged in different pin parts. The torque surfaces are preferably formed in the rear pin part.

摘要： A modular boring head includes a tubular main body having an internal thread with a first pitch and a pair of axially extending cantilevered members. A movable rod engages the tubular main body such that the movable rod is movable with respect to the tubular main body in an axial direction, D. The movable rod has an internal thread with a second pitch different than the first pitch. A leadscrew is disposed within the tubular main body and has a plurality of gear teeth. Rotation of the leadscrew causes the pair of axially extending cantilevered members of the tubular main body to cooperatively engage with the plurality of gear teeth of the leadscrew in such a manner so as to produce an audible and tactile click, each click being indicative of a distance the movable rod is displaced with respect to the tubular main body.

摘要： The invention relates to a method for producing a coated body, with a substrate and a coating arranged on the substrate, which coating comprises at least one base layer applied to the substrate and at least one metal carbide-containing layer arranged over the base layer, which layers are applied by means of magnetron sputtering. Furthermore, the invention relates to a coated body produced according to the method.

摘要： A rotary cutting tool (10) has an axis of rotation (R) and a tool body (12) extending along the axis of rotation (R) and having at least one coolant channel (30). At least a portion (32) of the at least one coolant channel (30) is formed by a groove (40) in a circumferential face (42) of the tool body (12). Furthermore, the at least one coolant channel (30) in the portion (32) of the groove (40) is closed in the radial direction by an add-on part of the rotary cutting tool (10) attached to the tool body (12). Furthermore, a method for manufacturing such a rotary cutting tool (10) is provided.

摘要： A modular rotary cutting tool includes a cutting head for insertion into a support. The cutting head has a coupling pin having torque surfaces and clamping surfaces formed on its outer peripheral surface. The coupling pin is divided into a front pin part and a rear pin part. The front pin part is defined by a circumferential groove. Stop surfaces for an axial pullout prevention are formed between the front pin part and the rear pin part. The torque surfaces and the clamping surfaces are arranged in different pin parts. For example, the clamping surfaces are preferably formed on the front pin part and the torque surfaces are preferably formed on the rear pin part. The clamping surfaces taper radially inward in a direction of the front cutting part at an angle of inclination, α2, with respect to the axis of rotation. Other variants and embodiments are broadly contemplated herein.
