Thread Rolls


Other Products


To produce circular thread rolling dies to suit most, and can be supplied for both helical, plunge and annular thru rolling.


Only high-quality cold work steel is used in our processes. Furthermore, specially developed special purpose steel alloys surpass even the most stringent of requirements in terms of surface quality, structural integrity and service life.

  Manufacturing quality

Special hardening and grinding processes as well as our continuous precision machining have enabled us to significantly reduce wear behaviour, thus lowering your tooling costs. Our continuous development means continuous quality improvements and reliability of our products.

  Special radius run out

Our special precision ground radius run outs were developed for Rolls Royce over 30 years ago. Reduces edge pressure of the die allowing the dies to create a full thread, up to the shoulder minus 0.5 of the pitch.

  Final inspection

Inspection of each die with regard to hardness, concentricity, bore diameter, profile accuracy documented. On site testing and development of our products is offered to our customers.


Fastest possible delivery of all established taps, thread rolling dies and profile dies for virtually all rolling systems. We distinguish ourselves by means of our flexibility, ensuring our customers the shortest possible lead times and thus reducing downtime, and by means of our outstanding price-performance ratio.


We carry out regrinding work both on our own taps and dies and those of other manufacturers, and, in doing so, we guarantee dimensional accuracy, through our final inspection process.
