It carries a 22NR428 insert style designation and is manufactured from micrograin solid carbide with an AlTiN coating applied via a PVD process. The insert features a 1\/2-inch inscribed circle and cuts at 4 threads per inch with a 60-degree included angle. This geometry is engineered for precision thread-form accuracy on demanding tubular and rotary shoulder connection applications. Machinists and CNC operators working on oilfield or energy-sector components will find this insert suited to a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for internal threading operations on API Rotary Shoulder Connection profiles, commonly encountered in oilfield drilling equipment, downhole tooling, and related energy-sector components. The universal primary workpiece material rating spans multiple material groups including cast iron, non-ferrous, stainless, non-metals, steel, and heat-resistant alloys. It is sized for use in compatible 22NR-style laydown insert toolholders and is appropriate for both production and repair threading on CNC lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for enhanced edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating via PVD process for extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e4 TPI thread form with 60-degree included angle, matched to API Rotary Shoulder Connections standard\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal thread orientation in a laydown-style 22NR insert format\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inscribed circle with a cutting edge to theoretical edge length of 0.080 inches and face-to-tip centerline of 0.100 inches\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering steel, stainless, cast iron, non-ferrous, heat-resistant alloys, and non-metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 22NR-style laydown threading insert toolholders configured for internal API Rotary Shoulder Connections thread profiles.

Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torque key or clamping screw driver specified by the toolholder manufacturer to secure the insert  -  do not overtighten the clamping screw. Confirm insert seating and alignment before initiating a threading pass to avoid thread-form error or insert fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 22NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Laydown\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: AC22F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Coated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: API Rotary Shoulder Connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.080 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.100 inches\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TOOL-FLO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5121000AC22F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOOL-FLO","offers":[{"title":"Default Title","offer_id":67909770117426,"sku":"5121000AC22F","price":347.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1182f6fc9b1c2458778506413c6d2a12.jpg?v=1791191913","url":"https:\/\/voomisupply.com\/products\/tool-flo-5121000ac22f-threading-insert-4-tpi-1-2-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
