Built from micrograin solid carbide with a PVD-applied TiAlN\/TiN coating in grade CP500, this insert delivers consistent thread geometry on difficult-to-machine materials. It carries a 2.5mm pitch, a 60-degree included angle, and a right-hand cutting orientation. The A2 chipbreaker geometry promotes controlled chip evacuation during continuous threading passes. Machinists and CNC operators in production and job-shop environments install this insert as part of the Snap Tap series tooling system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external ISO thread turning in materials coded M, with stainless steel listed as the primary workpiece material. The 3\/8-inch inscribed circle fits compatible laydown insert pockets sized for the 16ER insert style. The CP500 grade with PVD coating is selected for its wear resistance and edge toughness in stainless and similar work-hardening alloys. It is appropriate for both roughing and finishing thread profiles where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate with PVD TiAlN\/TiN coating in CP500 grade for wear resistance on stainless steel\u003c\/li\u003e\n  \u003cli\u003e2.5mm ISO pitch, 60-degree included angle, right-hand external thread geometry\u003c\/li\u003e\n  \u003cli\u003eA2 chipbreaker promotes controlled chip flow during threading passes\u003c\/li\u003e\n  \u003cli\u003e16ER insert style, 3\/8-inch inscribed circle fits standard laydown pocket toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.013 inches limits thread root stress concentration\u003c\/li\u003e\n  \u003cli\u003ePart of the Snap Tap series for repeatable, interchangeable threading performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting the 16ER laydown insert style with a 3\/8-inch inscribed circle pocket.

Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Verify insert pocket cleanliness and seating surface condition before each insert change to maintain thread accuracy.
