It carries manufacturer grade 1020 solid carbide construction with a PVD-applied TiN coating for wear resistance and edge retention in demanding threading applications. The insert runs a right-hand cutting geometry, produces 3 threads per inch, and fits a 5\/8 inch (15.88 mm) inscribed circle toolholder seat. At 7 mm (0.2756 inch) thick with a single tooth per side and an included angle of 60 degrees, it is sized for precision Acme thread profiles in both production and maintenance-repair machining environments. Machinists and CNC operators install this insert as part of the CoroThread 266 system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external Acme threading operations in metalworking environments. It is suited to production turning of lead screws, power screws, and similar components where Acme thread form accuracy is required. The CoroThread 266 series is a structured laydown insert platform used in both light-duty and medium-duty threading passes. The 3 TPI pitch targets coarse Acme applications typically found in industrial machinery, valve stems, and linear-motion hardware. Installation is performed by machining professionals working on CNC turning centers or manual engine lathes equipped with compatible CoroThread 266 toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand external Acme thread geometry at 3 TPI and 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch (15.88 mm) inscribed circle fits CoroThread 266 series holders\u003c\/li\u003e\n  \u003cli\u003e7 mm (0.2756 inch) insert thickness with 6.50 mm mounting hole diameter\u003c\/li\u003e\n  \u003cli\u003eSingle tooth per side for controlled thread form on each pass\u003c\/li\u003e\n  \u003cli\u003eF chipbreaker geometry for chip management during threading cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266 series laydown threading toolholders that accept a 5\/8 inch inscribed circle insert with a 6.50 mm hole diameter.

Power down the machine and engage all safety locks before indexing or replacing inserts. Use the correct Torx or insert-retention key specified by the toolholder manufacturer to seat the insert fully and avoid movement during the cut. Do not run the insert beyond visible flank wear limits, as a degraded edge will compromise Acme thread form accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 266\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroThread 266\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\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 3\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: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 7 mm (0.2756 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 6.50 mm (0.2559 inch)\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\u003eChipbreaker\u003c\/strong\u003e: F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches length x 1.54 inches width x 0.43 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5758112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51751795032370,"sku":"5758112","price":1563.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccf231290dee11ab915e377269a06c67_65ade7ba-cd94-49e2-9354-e77181c7b707.jpg?v=1788924298","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5758112-threading-insert-3-tpi-acme","provider":"Voomi Supply","version":"1.0","type":"link"}
