Iscar 5697621 Milling Insert Adkt 150532R-HM IC908 Carbide

Product Description

The ISCAR 5697621 is a solid carbide milling insert carrying the manufacturer designation ADKT 150532R-HM in grade IC908. It is a parallelogram-style, single-sided insert with a positive rake geometry and a right-hand cutting orientation. The insert features a TiAlN coating applied via PVD process over a submicron carbide substrate, delivering thermal resistance and edge stability during interrupted and continuous milling operations. With 2 cutting edges, a 0.126-inch corner radius, and a maximum depth of cut of 0.472 inches, it is designed for productive face and shoulder milling. Licensed machinists and CNC operators install this insert in compatible milling toolholders and cutter bodies.

This insert belongs to the HELIMILL series and is intended for milling steel, stainless steel, cast iron, superalloys and titanium, and hard materials. It is suited to both roughing and finishing passes in job-shop and production environments where a broad material range must be covered with a single insert grade. The screw-clamping holding method provides secure seating under high cutting forces. The HM chip breaker geometry supports consistent chip evacuation across the listed workpiece materials.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with indexable milling tooling. De-energize and lock out the machine spindle before seating or indexing any insert. Use the manufacturer-specified torx or hex key at the recommended screw-tightening sequence to ensure proper clamping without cracking the carbide. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert.
