Built from solid carbide in the CP500 grade (ISO material grade C5), it features a TiAlN\/TiN PVD coating applied through a physical vapor deposition process. The 16ER insert style fits compatible toolholders in the Snap Tap series and is configured for right-hand cutting. With a 60-degree included angle and an A2 chipbreaker geometry, this insert is engineered for controlled chip formation during threading operations on stainless steel and similar ISO M-group materials. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications on stainless steel workpieces classified under ISO material group M. The 18 TPI UN thread standard makes it appropriate for inch-series fastener and fitting threads common in industrial, fluid power, and mechanical assembly work. The CP500 grade with PVD TiAlN\/TiN coating resists built-up edge and heat at the cutting zone, which is a common challenge when threading austenitic stainless steel and other work-hardening alloys. It is used in both manual and CNC lathe setups where consistent thread form and surface finish are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide CP500 grade with PVD TiAlN\/TiN coating for wear resistance on stainless steel\u003c\/li\u003e\n\u003cli\u003e16ER insert style in the Snap Tap series for precise toolholder engagement\u003c\/li\u003e\n\u003cli\u003e18 TPI external UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eA2 chipbreaker geometry for controlled chip flow during threading passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting configuration for standard external thread direction\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle diameter; 0.1366 inches thick\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Snap Tap series toolholders accepting the 16ER insert style.
