Built from solid carbide micrograin substrate with a CP500 manufacturer grade, this insert carries a PVD-applied TiAlN\/TiN coating for wear resistance across a wide range of workpiece materials. The 16ER insert style seats in compatible laydown toolholders and cuts right-hand external threads per the Acme thread standard with a 29-degree included angle. With an inscribed circle of 0.375 inches and a thickness of 0.1366 inches, this insert suits production and maintenance threading operations performed by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external Acme thread generation on lathes and CNC turning centers. The Acme thread form is commonly found on lead screws, vises, linear actuators, and power-transmission components in industrial and machinery applications. The CP500 grade with universal material compatibility rating makes it appropriate for use on cast iron, steel alloys, non-ferrous metals, and certain high-temperature alloys. The Snap Tap series designation indicates compatibility with the corresponding toolholder system for secure, repeatable insert positioning during threading passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate with CP500 grade for extended tool life\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN\/TiN coating enhances heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand external Acme thread form at 8 TPI with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eUniversal primary workpiece material compatibility covering cast iron, steel, non-ferrous, and superalloys\u003c\/li\u003e\n\u003cli\u003e16ER laydown insert style for use in Snap Tap series toolholders\u003c\/li\u003e\n\u003cli\u003eISO-standard insert geometry for consistent fitment and indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SECO Snap Tap series laydown threading toolholders accepting the 16ER insert style.

Power down and lock out the turning machine before changing or indexing the insert. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Follow the toolholder manufacturer torque specifications for the clamping screw rather than applying general estimates, and verify thread pitch setup with a test pass before committing to full-depth cuts.\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 Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide 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 Applied\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO Codes K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\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: 00049958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559900086578,"sku":"00049958","price":123.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03292d5743429426eb6f8626f95721d0.jpg?v=1786443854","url":"https:\/\/voomisupply.com\/products\/seco-00049958-threading-insert-8-tpi-acme-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
