It features a 3ER insert style with a 60-degree included angle, a TiAlN coating applied via PVD process, and a VTX manufacturer grade. The inscribed circle measures 9.53 mm (3\/8 inch) and the insert thickness is 3.60 mm. Designed for right-hand threading operations, this insert is suited for use on CNC lathes and turning centers where consistent thread profile accuracy is required. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external UN thread cutting on a wide range of workpiece materials. The universal primary workpiece material classification covers material codes H, K, M, N, P, and S, making it applicable across steel, stainless steel, cast iron, non-ferrous metals, high-temp alloys, and similar materials. It is suited for standard-series threading applications where ANSI B1.1:74 UN thread form compliance is required. Typical use cases include threading on shafts, fasteners, fittings, and other externally threaded components in production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN PVD coating for wear resistance and heat tolerance\u003c\/li\u003e\n\u003cli\u003eVTX grade optimized for universal workpiece material compatibility across H, K, M, N, P, and S material codes\u003c\/li\u003e\n\u003cli\u003e3ER insert style, 60-degree included angle, right-hand cut for standard UN external threads\u003c\/li\u003e\n\u003cli\u003e40 TPI thread pitch conforming to ANSI B1.1:74 UN thread standard\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side design for precise thread form engagement\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 9.53 mm (3\/8 inch) with 3.60 mm thickness for laydown toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown threading toolholders accepting the 3ER insert style with a 3\/8-inch inscribed circle.

Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp  -  do not overtighten by hand estimation. Verify insert seating and thread profile with a thread gauge before resuming production cuts.\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 40\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: 9.53 mm (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.60 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\u003eSeries\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B1.1:74, ISO 9001:2008\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: 53669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67906241921330,"sku":"53669","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f713f09d129293ba4eb8c205c710a302_d68bc0a5-e049-48ca-bc50-14508fe7467e.jpg?v=1791166460","url":"https:\/\/voomisupply.com\/products\/vargus-53669-laydown-threading-insert-3er-40-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
