Iscar 3323587 Somt 1706RM-T IC808 Milling Insert

Product Description

The ISCAR 3323587 is a solid carbide milling insert designed for high-feed face milling in demanding metal removal applications. It carries the ANSI designation FFQ4 SOMT 1706RM-T IC808 and is built to the MILL4FEED series standard. The insert measures 17.5 mm wide and 6.00 mm thick, with a 2.50 mm corner radius and an inscribed circle of 0.6890 inches. The IC808 grade is a submicron solid carbide substrate finished with a multilayer PVD coating — TiAlN, AlTiN, and TiN — providing wear resistance and thermal stability during interrupted cuts and variable-feed conditions. Four cutting edges are available per insert, and the positive rake geometry with a T-Land cutting edge style helps reduce cutting forces on the spindle.

This insert is intended for use in the ISCAR MILL4FEED FFQ4 cutter series and suits a wide range of metalworking applications including roughing and semi-finishing on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The RM chip breaker geometry is suited for conditions where chip control and stable cutting action are priorities. The insert is screw-held and features a neutral hand orientation, making it compatible with standard FFQ4 toolholders used in CNC milling centers across job shop and production environments. Maximum depth of cut is 2.00 mm.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and manufacturer-specified insert screws when securing the insert to avoid seat deformation or screw failure. Inspect the pocket seat for chips or debris before installing a fresh insert to ensure proper seating and repeatable runout.
