Iscar 3103546 Indexable Square-shoulder Face Mill 2in

Product Description

The ISCAR 3103546 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining applications. Part of the Helialu series and carrying the cutter style designation HM90 FAL-22, this tool accepts two HM90 APCR 2206 inserts held in place by a clamp and screw method. It delivers a maximum cutting diameter of 2 inches, a maximum depth of cut of 0.807 inches, and a 0/90 degree lead angle for true square-shoulder profiling. Through-coolant capability supports chip evacuation and tool life in demanding cuts. This tool is installed and set up by machinists and CNC mill operators working in production or job-shop environments.

The 3103546 is suited for square-shoulder face milling, ramping, and peripheral milling operations on ferrous and non-ferrous materials. With a maximum ramping angle of 10 degrees, it handles both straight and angled entry cuts. The 3/4-inch arbor hole diameter fits standard milling machine spindles and arbors. Its 2-inch overall height and 1.93-inch hub diameter make it appropriate for short-reach setups on vertical and horizontal machining centers. This cutter conforms to ISO standards and is catalogued under manufacturer reference HM90 FAL-D2.00-.75-22.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter body. Torque insert clamp screws to the tool manufacturer's specified values using the correct Torx or hex key — do not overtighten. Confirm insert seating and arbor runout with a dial indicator before initiating a cut.
