ISCAR’s new HM90 APCR 220605-CS grooved inserts put an end to chip jamming problems in rough milling of aluminum, where chips can pile up like snowballs. They are a part of ISCAR’s growing HELIALU HM90 line of inserts tailored specifically for aluminum milling.
With two grooves pressed into each polished cutting face,
the inserts split aluminum chips into a manageable size for easy,
reliable evacuation despite the application’s characteristic high
chip volume.
The 22 mm inserts, each with two edges, are designed to optimize metal removal over the full range of aluminum roughing conditions, from high power/low speed to high power/high speed. They work especially well with ISCAR’s new HM90 EAL/FAL…22 aluminum rough milling cutters. Besides reliably clearing chips, the inserts conserve power and reduce chatter in long-overhang setups.
The inserts feature a cavity on the bottom to ensure correct mounting in cutter chip pockets equipped with standard spring pins.
For optimum chip control, ISCAR recommends using the HM90 APCR chip-splitting insert only in cutters with an even number of flutes.
