The present invention relates to embodiments of a cutting tool holder (10) having at least one insert pocket (13), wherein at least one insert pocket comprises a side surface (15) and at least one antirotation stop (16) protruding from the side surface. The antirotation stop may comprise at least two substantially planar surfaces. In certain embodiments, the cutting tool holder may have a pocket which comprises a bottom surface and an antirotation stop having three substantially planar surfaces that are substantially perpendicular to the bottom surface. The antirotation stop may be integral to the tool holder or may be produced separately and attached, either permanently or temporarily, to the tool holder. Embodiments may further comprise additional antirotation stops is desired by the machining application. In one embodiment, the cutting tool holder includes an insert pocket in the tool holder and at least one antirotation stop protruding from at least one of a side wall and the bottom surface of the insert pocket, wherein the antirotation stop comprises at least two substantially planar surfaces. A cutting insert (12) may be secured in the tool holder, wherein the cutting insert has a recess (17) having a shape that is non-complementary to the shape of the antirotation stop and may be made from tungsten based carbide or cermet.

A cutting insert rotated about its axis may be utilized during a metalworking operation and applied against the rotating workpiece to enhance tool performance. The cutting insert is secured within a toolholder having features to secure the insert but at the same time make for efficient removal of the insert from the toolholder.

A round cutting insert with a reverse anti-rotation feature that can be manufactured easily and inexpensively is disclosed. The round cutting insert includes a plurality of dimples formed on a first surface and another plurality of dimples formed on a second, opposing surface. The round insert is reversible and indexable. The round cutting insert is removable received in an insert receiving pocket in a tool body. The insert receiving pocket includes a single projection that is capable of being received in one of the plurality of dimples. The cooperation between the projection and one of the plurality of dimples prevents rotation of the round cutting insert when mounted in the insert receiving pocket. The plurality of dimples and the projection can be any desirable complimentary shape, such as a slot, a V-shape, a wagon wheel, a sports wheel, a pyramid, and the like.

A cutting insert rotated about an axis may be utilized during a metal working operation and applied against the rotating workpiece to enhance tool performance. Coolant may be provided through the central bore of the cutting insert utilizing bypass ports around the threaded hold-down bolts. Additionally, the cutting insert may be held within the toolholder pocket utilizing hoop walls which follow a serpentine path to provide flexibility. Finally, relative rotation of the cutting insert with respect to the toolholder body may be prevented utilizing a pair of protrusions within the toolholder pocket which engage a pair of recesses within a side of the cutting insert.

A turning insert formed for chip-cutting metal machining of a workpiece that rotates in a direction of rotation at a first speed of rotation around a workpiece axis, the turning insert including a front surface, an envelope surface, and a circular cutting edge located where the front surface meets the envelope surface. The cutting edge extends around the front surface and lays in a plane that forms an angle α with the envelope surface. A tool axis extends through the turning insert in a normal direction in respect of the plane, and the turning insert, during the chip-cutting metal machining, is formed to rotate around the tool axis at a second speed of rotation. The envelope surface forms a chip surface and is arranged to meet chips formed in the chip-cutting metal machining, and the chip surface includes chip breaking means.

A family of cutting inserts includes a plurality of different inserts, each having a different geometry. Each insert of the plurality of different inserts is adapted to be mounted in a common insert-receiving pocket on a toolholder of a milling cutting tool so that an outer diameter generated by the milling cutting tool is the same, regardless which insert of the plurality of inserts is mounted in the pocket.

The invention related to a milling tool (1) for machining work pieces, comprising at least one blade that is arranged in a radial manner on the milling head (2) that is rotationally mounted on a rotationally symmetrical designed Y-axis (4) on the milling head. According to the invention, said indexable cutting insert (2) is arranged below a tolerance play (7) in a freely rotating manner on the free end (8) of a mounting pin (9) secured in a detachable manner to the milling head (3) below the clamping seat. The freely rotationally mounted indexable cutting insert (2) is mounted or surrounded on the entire surface of the rear side (10) and on certain pats on the front side (11) such that the mounting pin (9) does not detach itself from the material (12) of the milling head (3).

A cylindrical cutting tool for a tire detreading or machining machine, the circular blade of which has a beveled cutting edge, wherein the cutting edge is interrupted by at least one notch, that is to say a portion having a lower axial height than the cutting edge.

The invention relates to a component for holding down measuring leads and measuring devices in a groove (6), provided therefor and having holes (7), of a machine part (5). It is characterized in that the component is designed in the form of a disk (1) which has a cutting edge (3) on its circumference, the cutting edge (3) not being formed continuously over the entire circumference but consisting of two partial cutting edges (3', 3'') circumferentially opposite one another. In addition, the disk (1) has a central opening (2) in the form of a hexagon socket. For fitting, the disk (1) is put into the hole (7) in such a way that its two partial cutting edges (3', 3'') point in the longitudinal direction of the groove (6), then a hexagon socket key is inserted into the opening (2) of the disk (1) and the key is turned while the disk (1) is pressed down at the same time, so that the cutting edges (3', 3'') cut into the material of the machine part (5) and jam tight.
