Part of the CoroThread 266 series, it features a solid carbide substrate with a PVD-applied TiCrAlN\/TiN coating for extended tool life in demanding threading operations. The insert produces right-hand internal UN threads at 8 threads per inch (TPI) with a 60-degree included angle. The 3\/8-inch inscribed circle and 5\/32-inch thickness conform to standard 266-series toolholder geometry. Typical users include machinists and CNC operators in production and job-shop environments working on threaded bores in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on lathes equipped with CoroThread 266-compatible toolholders. The single-tooth-per-side profile allows precise thread form control, making it appropriate for tight-tolerance UN threaded bores in production runs and prototype work. The A chipbreaker geometry supports controlled chip flow in through and blind-hole applications. The PVD TiCrAlN\/TiN coating provides wear resistance and thermal stability across a range of cutting conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiCrAlN\/TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal UN thread form at 8 TPI with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style with A chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (9.53 mm) inscribed circle with 0.1732-inch mounting hole diameter\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch (3.97 mm) thickness matches standard 266-series toolholder pocket dimensions\u003c\/li\u003e\n  \u003cli\u003eSingle tooth per side for precise thread profile control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266-series toolholders accepting size 16 laydown threading inserts.

Use the appropriate Torx or insert-clamping key to seat the insert fully in the pocket without over-torquing the clamping screw. Inspect the toolholder pocket for chips or wear before seating a new insert. Refer to the toolholder manufacturer's recommended cutting data for feed rate and depth-of-cut parameters when threading.\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: 1135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 8 TPI\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: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/32 inch (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 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: TiCrAlN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 5782015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727866396978,"sku":"5782015","price":614.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0a3b692b1a873af3d1f39acf28f9a3f.jpg?v=1793374725","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5782015-threading-insert-un-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
