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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3 inch maximum cutting diameter for mid-range face and shoulder milling\u003c\/li\u003e\n\u003cli\u003e0\/90 degree lead angle produces true square shoulders in a single pass\u003c\/li\u003e\n\u003cli\u003eAccepts 3 HM90 APCR 1605 style inserts with clamp and screw retention\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support for improved tool life and chip control\u003c\/li\u003e\n\u003cli\u003eMaximum ramping angle of 6.70 degrees supports helical and ramp entry strategies\u003c\/li\u003e\n\u003cli\u003eISO standard construction for broad insert sourcing compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible inserts are HM90 APCR 1605..R-P style.
