A cutting tool may include a cutter body, and a cutting insert group coupled to the cutter body, wherein the cutter body includes a working length, wherein the cutting insert group forms a continuous cutting edge, and wherein the continuous cutting edge extends continuously through the working length of the cutter body.

A cutting tool rotatable about a tool axis, having a cutting body and at least one indexable, single-sided cutting insert removably secured in an insert receiving pocket of the cutting body. The cutting insert has opposing upper and lower surfaces with a peripheral side surface extending therebetween and a central axis passing therethrough. First and second clamping bores extend between and open out at the upper and lower surfaces. First and second primary cutting edges are formed at the intersection of the upper surface and the peripheral side surface. The lower surface includes first and second annular recesses communicating with the first and second clamping bores, respectively, and first and second recess channels extending from the first and second clamping bores, respectively, to the peripheral side surface. The first and second recess channels extend parallel to a longitudinal first plane containing the central axis.

In an embodiment, a cutting tool includes a holder and a cutting insert. The holder is elongated and includes an insert pocket that is located on a side of a first end. The cutting insert is secured to the insert pocket. The cutting tool further includes a clamp that fastens the cutting insert in the insert pocket, and a screw that comes in contact with the cutting insert and is secured to the insert pocket. The screw includes a first surface including a first engagement portion on a first surface that is located on a side of the first end. The first engagement portion is located within a through-hole included in the screw in a front view of the first end.

A milling cutter includes a milling drum having a body with a first end, a second end, an outer surface extending around a circumference of the body between the first and second ends, and a slot formed in the outer surface. The milling cutter also includes a cutting insert positioned at least partially within the slot and removably secured to the body. The cutting insert includes a cutting profile defined by rounded peaks and pointed valleys to cut a tooth form into a saw blade.

A rotary cutting tool includes a cutter body having a plurality of insert-receiving pockets. Each pocket includes a bottom support surface, an axial support surface, a radial support surface, a top clearance surface and an intermediate clearance surface extending between the axial support surface and the top clearance surface. A cutting insert includes a helical top surface, a helical side surface, a side surface opposite the helical side surface, a pair of opposed side walls, a bottom surface, and a cutting edge formed at an intersection between the helical top surface and the helical side surface. The cutting insert further includes an undercut for accommodating the axial support surface, the top clearance surface and the intermediate clearance surface of the pocket when the cutting insert is mounted in the pocket.

The invention relates to a milling tool for gear milling. The tool body is equipped with tangentially mounted milling inserts having four cutting edges and two holes, only one of which is utilized for a fixing screw in two of totally four index positions. By locating a screw hole in the seat of the milling insert at a distance from the radial support surface of the seat that is greater than the distance between an individual hole and a distal end of the milling insert, a clamping force is provided by means of the inherent elasticity of the fixing screw. In such a way, the milling insert is pressed against the radial support surface. By means of a transversal eccentricity, the milling insert is also pressed against a tangential support surface in the seat. By means of this construction, the two holes in differently long milling inserts can be formed with equally large distances from distal ends. Thereby, one and the same tool body can be equipped with differently long milling inserts.
