It carries a PVD-applied TiCrAlN\/TiN dual-layer coating that provides wear resistance and thermal stability during high-speed threading operations. The insert features a 60-degree included angle and a single tooth per side, making it well suited for precision internal thread forming on CNC lathes and turning centers. Machinists and toolroom professionals install this insert as a replaceable cutting element in compatible CoroThread 266 toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is used in precision machining environments where consistent UN internal thread profiles are required. Typical applications include threading bores in workpieces made of steel, stainless, and similar materials in production turning operations. The C chipbreaker geometry helps manage chip flow in internal threading passes. The insert size code is 16, with a 3\/8 inch (9.53 mm) inscribed circle and a 5\/32 inch (0.1563 inch decimal) thickness, fitting toolholder pockets designed for the 266 insert style.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiCrAlN\/TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand internal UN thread profile at 14 TPI with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eC chipbreaker geometry for controlled chip evacuation in internal threading\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle with 5\/32 inch insert thickness (0.1563 inch decimal)\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side for precise thread form accuracy\u003c\/li\u003e\n\u003cli\u003eCoroThread 266 series insert style 266, size code 16\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroThread 266 series toolholders accepting insert style 266, size code 16, with a hole diameter of 0.1732 inch (4.40 mm).

Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torx or hex key specified for the CoroThread 266 toolholder clamp screw and ensure the insert seats fully and evenly in the pocket before resuming cuts. Do not overtighten the clamp screw, as solid carbide inserts are brittle and can crack under excessive clamping force.\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: 16\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\u003eSeries\u003c\/strong\u003e: CoroThread 266\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: 14\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: C\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 (0.1563 inch decimal \/ 3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (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\u003eWeight\u003c\/strong\u003e: 0.12 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: 5907005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748647895346,"sku":"5907005","price":607.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5929439e42fa52d950984d662a610ba4_3900db20-3928-4704-851e-f66c0af389db.jpg?v=1788896164","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5907005-laydown-threading-insert-14-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
