Expanded Range of ISCAR’s HELIDO Profiler Family

ISCAR has expanded its popular line of HELIDO ROUND H400 fine-pitch mills to improve profile machining and ramping over a wider range of applications. Included now are 10 and 16 mm inserts, to complement the original 12 mm insert. Matching cutters cover the 20-32 mm diameter range for endmills and 40-125 mm for face mills.
Unlike true rounds, HELIDO 400 ROUND inserts have a periphery that consists of bounding arcs with radii that would be found on pure rounds twice their size. It permits very high feed rates, while fitting more densely into a given size cutter, to create a finer-pitch tool.
The inserts are double sided, with helical cutting edges for gentler entry plus top-face geometry to create 10° positive-rake inclination. They feature ISCAR’s innovative SUMO TEC post-coating treatment that improves performance 35% on average. Each insert provides four 120° arcs.
Together with a dovetail clamping design in the cutter, the unique HELIDO 400 ROUND insert shape also creates four fixed indexing positions per side and firmer no-twist seating able to withstand high cutting forces. Fixed indexing positions also ensure that all four edges are used, and eliminate the uncertainties that lead to discarding of rounds which still have good edges.
