Built to the 3ER insert style with a VTX micrograin carbide grade and a PVD-applied TiAlN coating, this insert delivers consistent thread form and extended tool life across a broad range of workpiece materials. It cuts at 14 threads per inch and is sized with a 0.375-inch (3\/8-inch) inscribed circle and a thickness of 3.6 millimeters. The 60-degree included angle matches the NPT thread standard. Licensed machinists and CNC operators install this insert in compatible 3ER toolholders for precision pipe thread production.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external NPT threading applications in job shops, production machining, and maintenance environments. The universal material compatibility rating covers a wide range of metals including carbon steel, stainless steel, cast iron, aluminum, and high-temperature alloys, making it a practical single-insert solution for shops that thread multiple material types. It is particularly well suited for producing NPT pipe threads on fittings, nipples, and threaded pipe ends where a reliable, repeatable thread form is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide VTX micrograin grade for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating extends tool life on universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e14 TPI external NPT thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 3ER insert style for use in standard 3ER toolholders\u003c\/li\u003e\n\u003cli\u003e0.375-inch inscribed circle (9.53 mm) and 3.6 mm thickness for precise seating\u003c\/li\u003e\n\u003cli\u003eManufactured to ISO 9001:2008 and USAS B2.1:1968 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3ER-style laydown threading toolholders compatible with the 3ER insert seat geometry.

Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified seating procedure without over-torquing the clamping screw. Inspect the insert seat and clamp for wear or debris before seating a new insert. Verify thread form with a calibrated NPT go\/no-go gauge after the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VTX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN (Coated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\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\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008, USAS B2.1:1968\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911832076594,"sku":"51352","price":322.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f713f09d129293ba4eb8c205c710a302_c2a4057a-92c3-4cc8-8f48-293f7403d35c.jpg?v=1791221084","url":"https:\/\/voomisupply.com\/products\/vargus-51352-laydown-threading-insert-14-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
