Iscar 5604646 Milling Insert Lnet 125508-TN-MM IC928 Carbide

Product Description

The ISCAR 5604646 is a solid carbide milling insert carrying the ANSI designation LNET 125508-TN-MM in manufacturer grade IC928. It belongs to the TANGSLOT series and features a butterfly (LNET) insert shape with a neutral hand orientation and a negative rake angle of 25 degrees. The TiAlN coating is applied via PVD process, providing thermal and wear resistance suited to demanding cutting conditions. With four cutting edges, a 0.5000-inch inscribed circle, and a T-Land cutting edge style, this insert is engineered for slotting and milling operations in steel, stainless steel, superalloys, and titanium. It is held in the cutter body by screw clamping and is a single-sided insert.

This insert is intended for use in ISCAR FDN and SDN cutter series bodies that accept LNET-style inserts with the MM chip breaker geometry. It is suited to milling applications in ferrous and high-temperature alloy materials, making it applicable in aerospace, general machining, and heavy industrial environments. The IC928 grade is optimized for primary workpiece material codes P (steel), M (stainless steel), and S (superalloys and titanium), covering a broad range of challenging materials encountered in production machining. Machinists and CNC programmers working with TANGSLOT tooling systems will find this insert a direct-fit replacement for worn or damaged inserts in compatible cutter bodies.

Compatibility

Compatible with ISCAR FDN and SDN series cutter bodies designed to accept LNET 125508-TN-MM style inserts with MM chip breaker geometry.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten or use impact tools. Inspect the cutter body pocket and seating surfaces for wear or damage before seating a new insert.
