Manufactured to the 16IRM insert style specification and coated with TiAlN via a PVD process under the IC908 grade, this insert delivers high wear resistance and thermal stability during threading operations. It covers a thread-per-inch range of 48 to 8 TPI and a metric pitch range of 0.50 to 3.00 mm, making it a versatile choice across a broad range of threading applications. The insert is right-hand cut, carries an M chipbreaker designation, and is part of the ISCARTHREAD series. It is installed by machinists and CNC lathe operators in precision metalworking environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading on lathes and turning centers handling a wide range of workpiece materials. The IC908 grade with PVD TiAlN coating is optimized for universal application across material groups including steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and hardened materials. The 60-degree partial profile geometry supports standard unified and metric thread forms. This insert is well matched to production and job-shop environments where a single insert must perform across varied material grades without frequent grade changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 solid carbide grade with PVD TiAlN coating for extended tool life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal 60-degree partial profile geometry covers 48-8 TPI and 0.50 to 3.00 mm pitch range\u003c\/li\u003e\n  \u003cli\u003e16IRM insert style with M chipbreaker for reliable chip control in internal threading\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (9.53 mm) inscribed circle with 0.143 inch thickness for standard 16-size toolholders\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 cutting tool data representation standards\u003c\/li\u003e\n  \u003cli\u003eLaydown seating geometry for secure, repeatable insert indexing in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for 16IR-series internal threading toolholders accepting a 3\/8 inch inscribed circle laydown insert.
