Iscar 3102771 Square-shoulder Face Mill 3in Helialu

Product Description

The ISCAR 3102771 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Built to the Helialu series standard, it accepts HM90 APCR 1605 style inserts and holds three inserts using a clamp and screw method. The cutter delivers a 0/90 degree lead angle for true square-shoulder profiling and supports through-coolant flow to manage heat and chip evacuation during cutting. With a maximum cutting diameter of 3 inches and a maximum depth of cut of 0.622 inches, this body is sized for mid-range face milling and shoulder milling work on CNC machining centers and manual knee mills.

The 3102771 is suited for production and job-shop environments where repeatable square-shoulder profiles are required on steel, cast iron, and similar ferrous workpieces. The Helialu series cutter style designation is HM90 FAL-16, with a manufacturers catalog number of HM90 FAL-D3.00-1.00-16. It is installed by machinists and tooling setup technicians on vertical and horizontal spindle machines equipped with an arbor or adapter to match the 1 inch arbor hole diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be powered down and locked out before mounting or dismounting the cutter body. Verify arbor and adapter dimensions before mounting to confirm concentricity and secure seating. Torque insert screws and clamping hardware according to the insert manufacturer specification sheet supplied with the inserts, not generic values.
