Built from micrograin solid carbide in the CP500 grade, it features a PVD-applied TiAlN\/TiN coating for wear resistance and thermal stability. The insert carries a 60-degree included angle and an A1 chipbreaker geometry, supporting consistent chip control during threading operations on ferrous materials. With a 3\/8-inch inscribed circle and a measured thickness of 0.1366 inches, it fits standard toolholders designed for the 16NR insert style. Licensed machinists and CNC lathe operators handling production threading work are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on cast iron, stainless steel, and steel workpieces. It is part of the Snap Tap series and is designed for right-hand thread applications conforming to ISO standards. Typical use cases include finish threading of bores in production machining environments where consistent TPI accuracy and surface finish are required across medium to high volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate in CP500 manufacturer grade for toughness and edge retention\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN\/TiN coating for heat resistance and extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e18 TPI cutting geometry with 60-degree included angle for UN internal thread profiles\u003c\/li\u003e\n\u003cli\u003eA1 chipbreaker for controlled chip evacuation in threading passes\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard 16NR-style toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for conventional internal threading setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for toolholders accepting the 16NR insert style in internal threading applications conforming to UN thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamp screw torque driver as specified by the toolholder manufacturer — do not overtighten the clamp, as solid carbide inserts are brittle under point loading. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper location and prevent edge chipping on first contact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NR\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\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: A1\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 inches)\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: 0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\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: 00064512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557461557554,"sku":"00064512","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/319c6e96f6261ee43214db50d44b0969.jpg?v=1786388660","url":"https:\/\/voomisupply.com\/products\/seco-00064512-threading-insert-18-tpi-3-8-ic-un-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
