Configured in the 3ER style with an 18 TPI pitch, it cuts right-hand National Pipe Taper threads with a 60-degree included angle. The insert carries a TiN coating applied via PVD process, which improves surface hardness and extends tool life across a wide range of workpiece materials. With an inscribed circle of 9.53 mm (3\/8 inches) and a thickness of 3.6 mm, it fits standard 3ER-series toolholders. Manufactured to ISO 9001:2008 and USAS B2.1:1968 standards, it is suited for precision pipe thread production in machining environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external NPT threading applications in production and job-shop machining. The VKX grade and TiN finish make it compatible with a broad range of workpiece materials, including carbon steels, stainless steels, cast iron, aluminum, non-ferrous alloys, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S. It is well suited for threading pipe fittings, couplings, nipples, and similar components where NPT taper thread form and consistent pitch are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3ER insert style fits standard 3ER-series external threading toolholders\u003c\/li\u003e\n\u003cli\u003e18 TPI NPT thread form with 60-degree included angle for accurate taper pipe threads\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction in VKX grade for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating via PVD process for improved hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material compatibility across steel, stainless, cast iron, aluminum, and superalloys\u003c\/li\u003e\n\u003cli\u003eMeets ISO 9001:2008 and USAS B2.1:1968 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for 3ER-series external threading toolholders used in NPT pipe thread turning operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and indexing of threading inserts should be performed by a qualified machinist with the machine powered down and the spindle locked. Use the correct torx or hex key specified by the toolholder manufacturer to seat the insert securely without overtightening. Verify insert orientation and thread hand before resuming cutting operations. Follow applicable shop safety procedures and toolholder manufacturer guidelines when changing inserts.\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: VKX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\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\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (3\/8 inches)\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 (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 51476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67909776015666,"sku":"51476","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5380333568db365b8630eecf2a9f762_5955d905-0e7f-40f5-a872-1c379e49f9b6.jpg?v=1791192157","url":"https:\/\/voomisupply.com\/products\/vargus-51476-laydown-threading-insert-18-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
