The ISCAR HELIQMILL 390 line is an expansion of the HELIMILL line, which features a broad spectrum of insert geometries and sizes. Such a rich variety ensures success of the original HELIMILL practically in all shoulder milling operations, the company reports. The families effectively machine all types of engineering materials and the accuracy of machined surface and its roughness are good enough, according to the company.


The new line offers a triangular insert with three cutting edges. The length of the cutting edge of an insert with three edges is the same as in an insert with two: the new inserts are available with 10 and 15 mm cutting edge lengths. The insert with three edges has a stronger structure and its clamping into the pocket features high rigidity. The advanced cutting geometry of the new insert results in a precise 90° shoulder and a wiper flat provides excellent surface finish. The HELIQMILL 390 tools have impressive ramping-down abilities.


The new line incorporates all the advantages of HELIMILL; however, the added advantages of an extra cutting edge, extra-strong design, extra reliability and extra accuracy lead to extra performance, the company notes. This provides productive milling of true 90-degree in combination with an improved cost per cutting edge.


The HELIQMILL 390 inserts are produced from ISCAR’s SUMO TEC carbide grades, which contribute largely to increasing productivity, the company adds. The new tools are intended for machining shoulders, slots and planes. In addition, they can be a good choice in milling surfaces, ramping-down or helical interpolation such as pockets or cavities. The tools are available as endmills with shanks and face mills with a central bore.
