This double-sided, negative-rake rectangle insert features a TiAlN coating applied via PVD process, delivering wear resistance across a broad range of cutting conditions. With four usable cutting edges and an MJ chip breaker geometry, it is designed for productive face and shoulder milling in CNC machining centers. The insert measures 0.2360 inches in inscribed circle diameter and 0.1690 inches in thickness, with a corner radius of 0.0472 inches (3\/64 inch). Licensed machinists and CNC toolroom technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material grades P15, M15, K25, and S15. Its maximum depth of cut is 1.00 mm (0.0390 inches), making it appropriate for light-to-moderate finishing and semi-finishing passes. It fits cutter bodies within the EXN03, TXN03, HXN03-M, EXN03-C, HXN03-M-C, and EXN03-N series from TUNGALOY, and is secured via screw-holding method. It is a right-hand insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-sided insert with 4 cutting edges for extended tool life per insert\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for high-temperature wear resistance across multi-material applications\u003c\/li\u003e\n  \u003cli\u003eMJ chip breaker geometry optimized for controlled chip formation in mixed-material milling\u003c\/li\u003e\n  \u003cli\u003eNegative rake and honed cutting edge style reduce chipping on entry and exit\u003c\/li\u003e\n  \u003cli\u003eISO-standard LNMU0303ZER-MJ designation simplifies cross-reference and sourcing\u003c\/li\u003e\n  \u003cli\u003eCompatible with six TUNGALOY cutter body series for broad tooling flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TUNGALOY cutter body series EXN03, TXN03, HXN03-M, EXN03-C, HXN03-M-C, and EXN03-N.
