It operates at 4 threads per inch (TPI) and features a PVD-applied titanium nitride (TiN) coating that improves surface hardness and extends cutting life. With a 0.5 inch inscribed circle and a 0.187 inch thickness, this insert seats reliably in compatible toolholders. It is used in CNC lathes and manual threading operations by machinists and tool-and-die professionals working with Stub Acme thread forms common in power transmission and linear motion applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on Stub Acme profiles, which are widely used in lead screws, jacks, and actuator components. The 22UIR insert style is a standard laydown geometry indexed into a matching toolholder. It is appropriate for production and job-shop environments where consistent thread form accuracy and tool life are priorities. The solid carbide substrate handles interrupted cuts and harder workpiece materials better than high-speed steel alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and wear resistance in demanding threading applications\u003c\/li\u003e\n\u003cli\u003eTiN coating applied via PVD process for improved surface hardness and reduced friction\u003c\/li\u003e\n\u003cli\u003eRight-hand internal Stub Acme thread form at 4 TPI\u003c\/li\u003e\n\u003cli\u003e0.5 inch inscribed circle fits standard 22UIR-style toolholders\u003c\/li\u003e\n\u003cli\u003eLaydown insert style for repeatable indexing and consistent thread depth\u003c\/li\u003e\n\u003cli\u003eManufacturer grade BXC for broad material compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting the 22UIR insert style for internal Stub Acme threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists. Ensure the toolholder and insert pocket are clean and free of chips before seating the insert. Power down and lock out the machine before changing inserts. Follow the toolholder manufacturer's clamping torque guidance and verify thread form with a 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: 22UIR\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: BXC\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: Stub Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22UIR4STACMEBXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52023915774258,"sku":"22UIR4STACMEBXC","price":371.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/339f10d9541c2cec91baf3f89ca960b5_7fd4b5aa-b3c7-45c7-8cb0-e611df7b52e7.jpg?v=1790014394","url":"https:\/\/voomisupply.com\/products\/carmex-22uir4stacmebxc-laydown-threading-insert-4-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
