Part of the CoroThread 266 series, it features a TiN coating applied via PVD process, delivering consistent surface hardness and wear resistance in demanding threading operations. The insert has a 1\/2-inch (12.70 mm) inscribed circle, a thickness of 0.2190 inches (5.56 mm), and a hole diameter of 0.2244 inches (5.70 mm). It carries a 60-degree included angle with an F chipbreaker geometry. Installed by machinists and tooling technicians on CNC lathes and turning centers, this insert is suited for precision internal thread production in metalworking environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for internal Acme thread applications where tight pitch control and repeatable thread form are required. The Acme thread standard is commonly used in lead screws, power transmission components, and linear motion assemblies. The CoroThread 266 series laydown style is compatible with appropriately designated SANDVIK COROMANT toolholders designed for the 266 insert platform. The F chipbreaker geometry supports controlled chip evacuation during internal threading passes. This insert is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand internal Acme thread form at 5 TPI for power transmission and lead screw applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiN coating for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eF chipbreaker geometry for controlled chip formation during internal threading\u003c\/li\u003e\n\u003cli\u003e60-degree included angle consistent with Acme thread standard geometry\u003c\/li\u003e\n\u003cli\u003eCoroThread 266 series insert style 266, size code 22, manufacturer grade 1020\u003c\/li\u003e\n\u003cli\u003e1\/2-inch inscribed circle with a hole diameter of 0.2244 inches for secure clamping in compatible holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SANDVIK COROMANT CoroThread 266 series toolholders configured for laydown threading inserts with a 22 insert size code and right-hand internal Acme thread geometry.

Disengage the machine and lock out all power before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping torque without over-tightening the insert screw. Verify insert seating and clearance geometry before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 266\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 22\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: 1020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroThread 266\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: Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2190 inches (5.56 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2244 inches (5.70 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\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\u003eWeight\u003c\/strong\u003e: 0.31 pounds\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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5757951\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749900878130,"sku":"5757951","price":1158.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccf231290dee11ab915e377269a06c67_bafcdacd-aadd-415a-bd75-92e9c297d328.jpg?v=1788911879","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757951-threading-insert-5-tpi-acme-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
