Built from micrograin solid carbide with a PVD-applied TiAlN\/TiN coating, this insert handles right-hand external threading at a 3.0mm pitch with a 60-degree included angle. The CP500 grade is optimized for stainless steel and other difficult-to-machine materials. With a 3\/8-inch (0.3750 inch) inscribed circle and a thickness of 0.1366 inches, it seats securely in compatible 16ER-style toolholders. Machinists and CNC operators in production and job-shop environments rely on this insert for repeatable thread form accuracy on ISO-standard profiles.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on stainless steel workpieces, classified under material grade M. The A2 chipbreaker geometry and Snap Tap series design make it a practical choice for turning centers running ISO-threaded components in both light and medium-duty production runs. The PVD coating process preserves edge sharpness and extends tool life when cutting heat-resistant and work-hardening alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate with PVD TiAlN\/TiN coating for extended edge life on stainless steel\u003c\/li\u003e\n\u003cli\u003e3.0mm ISO pitch, 60-degree included angle for standard external ISO thread profiles\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry, 16ER insert style for use in standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003eA2 chipbreaker for controlled chip flow in stainless and M-grade materials\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle (0.3750 inch) with 0.1366-inch insert thickness for rigid seating\u003c\/li\u003e\n\u003cli\u003eCP500 manufacturer grade, part of the Snap Tap series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders that accept 3\/8-inch inscribed circle inserts with ISO external thread geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by a machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the correct torque wrench or insert key specified by the toolholder manufacturer when securing the clamping screw — do not overtighten. Inspect the insert pocket and clamping components for wear or debris before seating a new insert to maintain accurate thread form.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN (PVD Coated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 3.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0170 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Grade M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00077789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562525622578,"sku":"00077789","price":92.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c460d64adbb7468a627c8c54412aaf65.jpg?v=1786478738","url":"https:\/\/voomisupply.com\/products\/seco-00077789-threading-insert-3-0mm-iso-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
