Solid carbide taps, thread cutters and whirling thread cutters by Karnasch

The high speed cutting solid carbide taps and thread cutters by Karnasch in premium quality - small in detail, great in performance. For metalmachining of aluminum, copper, steel, GRP/CRP, graphite and plastics. 

The Karnasch tool series of solid carbide taps, thread cutters and whirling thread cutters for challenging thread cutting and tapping tasks. Precise results without burr formation when tapping or thread cutting. 

The range of Karnasch taps includes solid carbide machine taps, solid carbide Whitworth pipe taps, solid carbide fine thread machine taps and HSS-Co Cobalt + TIN coated taps. Available in diameters from M 3 to M 30, the various solid carbide taps can be used in hardened steel up to 63 HRC, cast iron materials and graphite. When machining with taps, use only a cutting paste with high-pressure additives. Suitable cutting pastes or cutting oils can be found in our coolant range.

The Karnasch solid carbide thread cutters enable the production of threads in abrasive materials. In sizes from M 4 to M 12, with a diamond coating, a 30° spiral and an additional countersinking step, the thread cutters can be used in graphite and composites. The solid carbide whirling thread cutters, due to the logarithmic relief grinding, achieve considerable improvements of tool lives. ​​​​​​​​​​​​​​Available in diameters from M 0.6 to M 3.0, the rake angle and relief ground remain stable, which increases process reliability. With the adjusted coatings, you achieve a consequent increase in productivity in metalcutting. 

Karnasch solid carbide taps and thread cutters are our solutions for the steadily growing challenges of our customers and for the high expectations of our tools' quality and machining results.

The new standard of whirling thread cutters

Excellent qualities for challenging manufacturing processes

VHM Gewindewirbler Werkzeug logarithmisch hinterschliffen

The solid carbide whirling thread cutters by Karnasch have polished surfaces which contribute not only to an excellent surface finish but also to an extreme sharpness of cutting edges. 

Due to the special profile shape the thread remains true to size, distortion-free and is shaped optimally. 

The process reliable chip removal is controlled by especially developed cutting edge geometries.

The range of Karnasch threading tools includes not only whirling thread cutters but also solid carbide thread cutters and solid carbide taps.
