Manufactured in the 3ER style with a 3\/8 inch (0.3750 inch) inscribed circle, this insert produces Whitworth-form external threads at 11 TPI. The VK2P micrograin carbide grade delivers a bright, uncoated finish suited for threading operations where a PVD coating process is specified but a bare substrate is preferred for certain work materials. Right-hand orientation is standard. This insert is intended for use by machinists, toolroom technicians, and CNC operators working to Whitworth thread standards.\u003c\/p\u003e\u003cp\u003eThis insert is applied in external threading operations on turned components where Whitworth thread profiles are required. Typical applications include production threading of fittings, fasteners, and mechanical components to B.S.84:1956, DIN 259, and ISO 228\/1:1982 standards. The 3ER style seats in compatible 3ER-series threading toolholders. Right-hand cutting direction suits standard lathe rotation for external thread profiles. Sold individually, with a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3ER insert style with 0.3750 inch inscribed circle for use in standard 3ER toolholders\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003eVK2P manufacturer grade with bright uncoated finish\u003c\/li\u003e\n\u003cli\u003e11 TPI external Whitworth thread form, right-hand cut\u003c\/li\u003e\n\u003cli\u003eConforms to B.S.84:1956, DIN 259, and ISO 228\/1:1982 thread standards\u003c\/li\u003e\n\u003cli\u003ePVD-capable substrate suitable for uncoated or coated tooling programs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3ER-style external threading toolholders compatible with a 0.375 inch inscribed circle insert seat.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC toolroom technicians. Ensure the machine spindle is fully stopped and the turret is de-energized before seating or replacing inserts. Use the manufacturer-specified torque wrench and clamp screw for the toolholder to secure the insert properly. Verify thread form and pitch against a thread gauge before running production parts.\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 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: VK2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\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: Whitworth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 11 TPI\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: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.375 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: B.S.84:1956, DIN 259, ISO 228\/1:1982\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 54020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67914500210994,"sku":"54020","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a650f2d7583b3f979b60c64e93123a63_f87e3d5c-02d3-4c3d-85b1-309e91abdfa5.jpg?v=1791249573","url":"https:\/\/voomisupply.com\/products\/vargus-54020-threading-insert-3er-11-tpi-whitworth-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
