Built to the 20NR insert style and manufactured in SECO grade CP500, this insert features a TiAlN\/TiN PVD coating applied for enhanced wear resistance and tool life across a wide range of workpiece materials. With a 0.248-inch thickness and a 1\/2-inch inscribed circle, it seats in compatible 20NR-style toolholders for right-hand internal threading operations. Machinists and CNC lathe operators use this insert for precision Acme thread profiles in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal Acme threading applications on a broad range of materials, including steels, stainless steels, non-ferrous metals, and cast materials, consistent with its universal primary workpiece material rating (ISO material codes K, M, N, P, and S). It belongs to the SECO Snap Tap series and is intended for use in lathe or turning center applications where right-hand internal thread forms are required. The 29-degree included angle conforms to the Acme thread standard, making it appropriate for lead screw, power transmission, and actuator threading work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CP500 grade for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN\/TiN PVD coating for extended tool life across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e3.5 TPI Acme thread form with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand internal thread orientation\u003c\/li\u003e\n\u003cli\u003e1\/2-inch inscribed circle, 0.248-inch thickness for 20NR-style toolholder seating\u003c\/li\u003e\n\u003cli\u003eISO-compliant insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 20NR-style laydown threading toolholders compatible with the Snap Tap series.
