Extending the application capabilities of its tangential Sumomill inserts, Iscar offers end mills to perform chamfering, countersinking and face milling operations. The tangential orientation of the inserts creates a stronger cutting platform, which increases edge life and eliminates fracture failures at higher cutting rates, even in unfavorable conditions, the company says.
The four-flute, 12-mm-diameter end mills are available in 30-, 45- and 60-degree geometries. According to the company, their small diameter and high flute density enables them to run at high table feeds in face milling applications.
The end mills’ Sumo Tec coating treatment is said to produce a smoother, more lubricious surface, with fewer thermal stresses and stress factors compared to an untreated plain PVD or CVD coating. As a result, the inserts can cut at cooler temperatures with less friction and with reduced risk of rupture.
