Abstract: Provision is made of a cutting tool, in particular a drill or a milling cutter, having a shank and a chip transporting portion, which receives a cutting insert, wherein the cutting tool is a hybrid composite body. Furthermore, a chip transporting portion for a cutting tool and also a process for producing a cutting tool are described.

Abstract: A cutting insert for use on a tool body includes a first member formed in a predetermined shape and a second member formed separate from the first member in a second predetermined shape and coupled to the first member. At least one of the first member or the second member comprise a number of cutting portions adapted to perform cutting operations on a workpiece.

Abstract: A cutting tool having a shaft with a longitudinal axis, wherein the cutting tool includes a first flute extending about the longitudinal shaft along a helix angle and a first cutting edge adjacent the first flute. The cutting tool also includes a second flute extending about the longitudinal shaft along a helix angle and a second cutting edge adjacent a second flute. The cutting tool further includes a third flute extending about the longitudinal shaft along a helix angle and a third cutting edge adjacent the third flute. The first cutting edge, the second cutting edge, and the third cutting edge are unequally angularly spaced from each other.

Abstract: A cutting tool for performing cutting operations on a workpiece when the cutting tool is rotated about a central axis by a machine tool, the cutting tool includes a generally cylindrical body disposed about the central axis. The generally cylindrical body includes a first end and an opposite second end. The cutting tool further includes a cutting portion and a mounting portion. The cutting portion is disposed at or about the first end of the generally cylindrical body and includes a number of cutting edges structured to engage the workpiece during cutting operations. The mounting portion is disposed at or about the opposite second end of the generally cylindrical body and is structured to be coupled to the machine tool. At least a portion of the generally cylindrical body comprises a molded portion formed via a molding process about the cutting portion in a manner that couples the cutting portion to the generally cylindrical body.

Abstract: An inventive workpiece features on at least parts of its surface a wear resistant hard coating comprising the following composition Al1-a-b-c-dCraXbSicBdZ, where x is at least one element from Nb, Mo, W or Ta; Z is one element or compound from N, C, CN, NO, CO, CNO; and 0.2<=a<=0.5; 0.01<=b<=0.2; 0<=c<=0.1; 0<=d<=0.1. Further a PVD process for depositing such a wear resistant coating is disclosed whereby at least one workpiece is installed in a vacuum coating system and said system is operated in a low pressure argon atmosphere utilizing at least two metal or metal alloy targets with at least temporarily addition of a reactive gas.

Abstract: A work piece or structural component is coated with a system of film layers at least one of which is composed of (AlyCr1-y)X, where X=N, C, B, CN, BN, CBN, NO, CO, BO, CNO, BNO or CBNO and 0.2?y<0.7, with the composition within said film being either essentially constant or varying over the thickness of the film continually or in steps, as well as a process for producing it.

Abstract: A method for forming the cutting edge and adjacent contoured surface area of rotary cutting tools utilizing a laser to remove material from the cutting end of the tool to create a predetermined point-by-point geometry is disclosed. Relatively complex surface and edge geometries may be formed by directing a laser beam toward the cutting end of the tool at an angle having a component that is normal to the surface of the cutting end. The laser beam is directed in multiple passes across the surface of the cutting end to remove material and form the desired cutting edge and adjacent three-dimensional contoured surface geometry.
