Iscar 5603643 Milling Insert Lnat 150632PN-N Mm IC928

Product Description

The ISCAR 5603643 is a solid carbide milling insert carrying the manufacturer designation LNAT 150632PN-N MM IC928. It belongs to the TANGMILL series and features a butterfly (LNAT) insert shape with a double-sided, neutral-hand design that provides four usable cutting edges per insert. The insert is coated with TiAlN via a PVD process, which extends tool life when cutting ferrous and difficult-to-machine materials. Key dimensions include an inscribed circle of 0.2360 inches, a thickness of 0.5460 inches, and an effective cutting edge length of 0.5906 inches. The corner radius measures 0.1260 inches (3.20 mm), and the maximum depth of cut is 0.2760 inches (7.00 mm). The cutting edge is honed with a negative rake and zero relief angle. Screw-clamping is the designated holding method.

This insert is intended for milling operations on steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. It is suited for face milling and shoulder milling applications in both production shops and maintenance environments. The MM chip breaker geometry is designed to manage chip flow across this range of workpiece materials. The insert meets ANSI and ISO 13399 standards and is identified by ANSI code LNAT 150632PN-N MM IC928. It is sold individually with a minimum order quantity of 10 units and is intended for use by machinists and tooling professionals in metalworking operations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable milling insert systems. The insert is secured via screw clamping; ensure the clamping screw and pocket are clean and free of chips before seating the insert. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket for wear or damage at each tool change to maintain accurate seating and cutting geometry.
