The latest generation of machine taps: The GSR-Silverlinie product line
Our latest generation machine taps are the result of state-of-the-art coating technology, excellent cutting geometry and the best high speed steel.
The advantages of these machine taps are clearly their long service life and innovative cutting geometry. These reduce thread friction and minimize the risk of breakage. The risk of deformation in the thread is negligible. In addition, polished grooves in the machine taps ensure better chip removal. The different coating options of the GSR-Silverlinie can be adapted to meet specific needs and customer requirements.
The GSR-Silverlinie machine taps are available for through holes and blind holes. The machine taps for through holes have a peel cut and straight grooves. The chip is removed from the bottom of the hole.
Whereas the machine taps for blind holes, the GSR-Silverlinie product line, have a spiral groove. Here the chip removal takes place above the borehole. Further information is available here.
