Threading with chip breaking

At EMO 2025, HORN is expanding its Supermini system with sintered geometries to include a variant for turning threads. The GM geometry is suitable for turning metric ISO internal threads in partial profiles. The chip breaker geometry generates short chips, even with difficult-to-machine and long-chipping materials. This reduces the risk of chip jamming, prevents chips from wrapping around the tool holder, and thus increases process reliability. In addition, the chip breaker facilitates chip control.

The inserts are suitable for producing metric internal threads in a core hole diameter of 5 mm (0.197") and above, in pitch sizes from 0.5 mm (0.028") to 1.5 mm (0.060"). The standard turning holders of the Supermini system are suitable as tool holders.
