Iscar 3103624 Indexable Square-shoulder End Mill 5/8 in

Product Description

The ISCAR 3103624 is a 4-flute indexable square-shoulder end mill from the Heliplus series, designed for high-performance milling operations in metalworking and machining environments. It features a 5/8-inch cutting diameter and a maximum depth of cut of 0.303 inches, making it suited for precise shoulder milling with consistent chip evacuation. The cylindrical shank measures 5/8 inch in diameter and 2.5 inches in length, with an overall assembly length of 3.5 inches. Through-coolant capability supports extended tool life and improved cutting conditions at the insert. This toolholder is installed and set up by machinists and CNC operators working with indexable milling systems.

The 3103624 is built for use in the HP E90AN-07 toolholder platform and accepts HP AN.. 0702.. insert style. The 90-degree lead angle geometry produces square shoulders in a single pass, which is a common requirement in mold, die, and general precision component work. It is appropriate for both horizontal and vertical milling machine setups where accurate shoulder profiles and tight tolerances are required. The through-coolant design makes it a practical choice for longer runs in difficult-to-machine materials where heat and chip buildup are primary concerns.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator familiar with indexable milling tooling. Ensure the machine spindle is fully stopped and the machine is powered down before mounting or indexing inserts. Use the appropriate torx or hex key to tighten the insert screw to the manufacturer-specified engagement level without over-torquing. Confirm runout and projection length against the workpiece setup before beginning a cut.
