Iscar Tools, the inventor of the HeliMill inserts, has launched the HeliIQMill 390 family, an evolution of inserts with one extra helical cutting edge.
The new cutters 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 90º shoulders, providing an improved cost per cutting edge for various milling applications.
The HM390 TPKT 1003PDR insert features .315 in. maximum depth of cut and the HM390 TDKT 1505PDR insert, .512 in. maximum D.O.C.
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.
