Iscar 5603507 Milling Insert Lnar 1106 Pn-n-p IC07

Product Description

The ISCAR 5603507 is a solid carbide milling insert conforming to the ANSI and ISO 13399 designation LNAR 1106 PN-N-P IC07. It features a butterfly insert shape with a negative rake geometry and a sharp cutting edge style, designed for tangential milling applications in demanding materials. The IC07 grade is an uncoated submicron carbide, optimized for cutting stainless steel, non-ferrous metals, superalloys, and titanium. With four usable cutting edges on a double-sided body, this insert delivers consistent performance across high-wear applications. It is held in place by a screw-lock method and is suited for use in the ISCAR TANGMILL cutter series.

This insert is intended for milling operations on stainless steel, non-ferrous metals, superalloys, and titanium in both production and job-shop environments. The PN chip breaker geometry and sharp cutting edge reduce cutting forces, which is particularly beneficial when machining work-hardening or gummy materials. A maximum depth of cut of 0.197 inches makes it appropriate for moderate-engagement tangential milling passes. It is installed by CNC machinists and tooling specialists setting up milling programs on vertical or horizontal machining centers.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the cutter body is secured before seating or removing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when tightening the insert screw; do not overtighten. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper seating and runout.
