Part of the CoroThread 266 series, it features a solid carbide substrate with a PVD-applied TiN coating for wear resistance and tool life. The insert produces right-hand internal threads at 11.5 threads per inch (TPI) with a 60-degree included angle and a 1\/2-inch (12.70 mm) inscribed circle. At 0.2190 inches (5.56 mm) thick with a 0.2244-inch hole diameter, it seats securely in compatible 266-series toolholders. Qualified machinists and toolroom technicians install this insert on CNC lathes and threading centers where precise NPT pipe thread forms are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal NPT pipe thread operations on lathes and turning centers in production machining, job shop, and maintenance environments. The NPT thread standard is used widely in North American pipe and fitting assemblies, making this insert applicable across industries including oil and gas, hydraulics, plumbing fabrication, and industrial manufacturing. The insert style code 266RL-22NT02A115E in manufacturer cataloging identifies the geometry, hand, thread type, and grade for precise toolholder matching. The chipbreaker designation A is suited for controlled chip formation during internal threading passes. This insert is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal NPT thread form at 11.5 TPI with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inscribed circle for use in 266-series 22-size toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo teeth per side geometry for efficient thread profile engagement\u003c\/li\u003e\n  \u003cli\u003eChipbreaker type A supports controlled chip evacuation on internal threading passes\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert with manufacturer grade 1020 carbide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT CoroThread 266 series toolholders accepting size 22 laydown threading inserts.

Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key torque driver specified by the toolholder manufacturer when seating the insert clamp screw — do not overtighten by hand estimation. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and thread accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: CoroThread 266\u003c\/li\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\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: A\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\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\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\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: 5758029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749148950834,"sku":"5758029","price":1379.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5929439e42fa52d950984d662a610ba4_484e6cc1-c9c4-421a-9036-818bd34bc898.jpg?v=1788902636","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5758029-threading-insert-11-5-tpi-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
