A new family of ISCAR endmills extends the benefits of tangential SUMOMILL inserts to chamfering, countersinking and face milling . Featuring the proprietary SUMO TEC coating treatment, ISCAR’s SUMOMILL have outperformed competitors by an average of 35% in many applications worldwide. The tangential orientation creates a fundamentally stronger cutting platform, which leads to longer edge life and elimination of fracture failures at higher cutting rates, even in unfavorable conditions.
SUMOMILL tangential endmills, all four-flute in 12 mm diameters, come in 30°, 45° and 60° geometries. In facemilling applications they can run at very high table feeds due to their small diameter and high flute density.
The proprietary SUMO TEC surface treatment produces a much smoother, more lubricious surface on the insert, with fewer thermal stresses and stress factors than would be found in an untreated plain PVD or CVD coating. This leads to cooler cutting (heat is a key enemy of machining inserts), less friction and much reduced risk of insert rupture. On average, SUMO TEC coated tools have proven to literally double throughput and reliably extend insert life by 40% vs. identical but untreated inserts.
