A major expansion of the ISCAR HELIDO 845-13 mill family brings the efficiency and economy of these popular tools to a wider size and application range. Key additions to the cutter line include extra-fine pitch cutters in the diameter range 2.0”-5.0” and coarse-pitch models with coolant ports serving every pocket. New HP and PL inserts are optimized to better handle austenitic cast iron, high temperature alloys, and stainless steels. Also added is a wiper insert to improve finish using fine-pitch cutters of 5” and larger. Inserts are positive rake to reduce machining forces, and feature helical cutting edges to create a gentler entry and exit. The SUMO-TEC post coating has improved performance by 35 percent on average. For more information go to [www.iscar.com].
