Iscar 40mm Heli3Mill 90° Indexable Milling Body

HELIMILL 390 cutter carry triangular inserts with three helical cutting edges, versus only two on the current tools. In addition, the construction of the new inserts is stronger compared to current two-edged inserts. The new family ensures productive milling of true 90° shoulders, providing an improved cost per cutting edge for various milling applications and have inserts available with 7, 10, 15 and 19mm cutting edge lengths. Due to their advanced cutting geometries, the inserts reduce cutting forces and power consumption. They can also be successfully applied for milling high temperature super alloys, that are popular in the aerospace industry.
