Our new bell-type thread milling cutters are mainly used in the production of external threads, external contours, large internal threads and large internal contours.

Due to a specially designed insert seat, the radial stop which is normally needed becomes superfluous, so the insert can be provided with a second cutting edge.

This second milling edge can be provided with another profile and/or another thread pitch, for example. In this way, you can for instance produce different threads with just one bell-type milling cutter and a set of milling inserts.

Advantages:

• Thread production almost independent of thread size and tolerance
• One tool only for right- and left-hand threads
• High reliability thanks to short chips
• Long tool life
• Repeated regrinding is possible
• Thread production down to the bottom of the hole / over the full bolt length
• Cost-efficient solution for small-series production
• Appropriate coatings for every application
• One holder only for both bolt and thread hole machining and for thread milling
• Variable diameters and lengths, adjusted perfectly to each individual application
• Internal coolant-lubricant supply
• High stability
