A ballscrew thread forming tap including a complete thread portion and a leading portion is to be screwed into a prepared hole provided in a workpiece so as to cause an inner circumferential surface of the prepared hole to be plastically deformed for thereby forming a ballscrew thread corresponding to an external thread provided in the complete thread portion. A screw thread of the external thread has a leading flank and a trailing flank, which are to be positioned on a front side of the trailing flank and on a rear side of the leading flank, respectively, when the ballscrew thread forming tap is screwed into the prepared hole. The screw thread is formed such that, in the leading portion, an indentation depth into the workpiece made by the leading flank is smaller than an indentation depth into the workpiece made by the trailing flank.

A hybrid threading tool defines a longitudinal axis and includes a cutting portion with a plurality of cutting teeth. The plurality of cutting teeth are configured to cut a first threading into a workpiece. The hybrid threading tool also defines a forming portion that is attached to the cutting portion and that is arranged therewith along the longitudinal axis. The forming portion includes a plurality of forming teeth configured to plastically deform the first threading into a second threading for the workpiece.

A hybrid threading tap includes a reamer portion and a thread cutting portion having a plurality of cutting teeth. The thread cutting portion is arranged with the reamer portion along the longitudinal axis. The reamer portion is configured to be advanced within a hole of a workpiece to plastically deform and expand the hole to an expanded hole and provide the expanded hole with a zone of residual compressive stress. The plurality of cutting teeth is configured to cut a threading into the expanded hole within the zone.

The present invention relates to a tap drill comprising a substrate and a coating, wherein the coating is deposited on at least a portion of the substrate comprising the head of the drill, the coating comprising a first layer deposited directly on the substrate and a second layer deposited atop the first layer, wherein the first layer is a wear resistant layer of (Al, Cr)N deposited by Hi PIMS and the second layer is a friction reduction layer, wherein the second layer is a metal carbide layer or a metal-carbide comprising layer deposited by using a physical vapor deposition (PVD) process of the type magnetron sputtering, preferably of the type HiPIMS.
