Manufactured to the 22ER insert style and graded HG330TR, it carries a TiC\/TiN coating that improves wear resistance and extends tool life in moderate-to-hard workpiece materials. The insert is configured for right-hand cutting with a 5 threads-per-inch (TPI) pitch and a 1\/2-inch inscribed circle. A relief angle of 1 degree supports clean thread form on Stub Acme profiles. This insert is installed and replaced by machinists and CNC operators performing precision threading work.\u003c\/p\u003e\u003cp\u003eThis insert is suited for shops producing threaded components that require Stub Acme thread forms, commonly found in power-transmission hardware, lead screws, and linear-motion assemblies. The internal thread configuration makes it appropriate for boring bars and internal threading toolholders used in both production and job-shop environments. The solid carbide substrate handles interrupted cuts and tougher alloys better than cermet alternatives, making it a practical choice for steel and stainless threading applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate provides rigidity and heat resistance during high-speed threading\u003c\/li\u003e\n\u003cli\u003eTiC\/TiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e5 TPI pitch matches standard Stub Acme thread form requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand internal configuration compatible with standard internal threading toolholders\u003c\/li\u003e\n\u003cli\u003e22ER insert style with 1\/2-inch inscribed circle for consistent seating in compatible holders\u003c\/li\u003e\n\u003cli\u003eRelief angle of 1 degree maintains accurate Stub Acme thread geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in internal threading toolholders and boring bars that accept the 22ER laydown insert style with a 1\/2-inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement should be performed by a qualified machinist or CNC operator with the machine in a full stop and all axes locked before indexing or swapping inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer to secure the insert without cracking the carbide. Verify thread pitch and insert orientation against the job setup sheet before resuming cutting operations. Inspect the insert seating pocket for chips or debris prior to installation to ensure proper insert contact and thread form accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 22ER\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: HG330TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\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: 5 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: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 1 degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H05768148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731921600818,"sku":"H05768148","price":340.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a843d23253a802dbfa10074f73beceb.jpg?v=1788736648","url":"https:\/\/voomisupply.com\/products\/hertel-h05768148-threading-insert-22er5-hg330tr-5-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
