Built to insert style 3JIR, it carries a TiAlN coating applied via PVD process, which improves heat resistance and extends tool life during threading operations. The insert features a 60-degree included angle, a 9.53 mm inscribed circle (3\/8 inch), and a thickness of 3.60 mm. The SCB chipbreaker geometry supports consistent chip control across a wide range of workpiece materials. This insert is used by machinists and CNC lathe operators on turning centers requiring precision pipe thread profiles.\u003c\/p\u003e\u003cp\u003eThe 53643 is suited for internal NPTF threading applications on lathes and turning centers in production and job-shop environments. Its universal primary workpiece material rating covers steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and other common materials, making it adaptable across varied production schedules. The NPTF thread form conforms to ANSI B1.20.3-1976, making it appropriate for hydraulic and pneumatic fittings, pipe connectors, and fluid-system components where pressure-tight thread engagement is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand internal NPTF thread form at 14 TPI per ANSI B1.20.3-1976\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with TiAlN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e60-degree included angle with SCB chipbreaker geometry\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 9.53 mm (3\/8 inch), thickness 3.60 mm\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material compatibility: steel, stainless, cast iron, non-ferrous, and high-temperature alloys\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side for precise thread profile control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for lathe and CNC turning center toolholders accepting 3JIR-style laydown inserts with a 3\/8-inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts should be installed and replaced by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the toolholder pocket and verify clamp torque per the toolholder manufacturer specifications.
