Part of the CoroThread 266 series, this left-hand insert features a TiCrAlN\/TiN coating applied via PVD process, providing wear resistance and extended tool life under demanding cutting conditions. It carries a 1.1 mm cutting width and a maximum depth of cut of 1.3 mm, making it suited for precision internal and external groove profiles in small-diameter work. Machining professionals and CNC tooling specialists install this insert as a direct replacement component in compatible CoroThread 266 toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision turning applications where controlled groove geometry is required, including thread relief grooves, snap-ring grooves, and shallow profiling cuts. The neutral rake angle and C-style chip breaker support consistent chip evacuation in both ferrous and non-ferrous materials. The insert size designation is 0.375 with an ISO code of 254LG-16CC01-110 1135 and manufacturer grade 1135, placing it in a defined performance tier for finishing and semi-finishing cuts. It is appropriate for production environments and job-shop settings where repeatable groove tolerances are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCrAlN\/TiN coating for elevated wear resistance\u003c\/li\u003e\n  \u003cli\u003e1.1 mm cutting width with a maximum depth of cut of 1.3 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting orientation for specific toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle with C-style chip breaker for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.08 mm for precise groove floor geometry\u003c\/li\u003e\n  \u003cli\u003eMulti-use insert compatible with CoroThread 266 series tooling system\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 insert seat size 0.375.

Disengage the machine spindle and confirm the turret is fully indexed and locked before handling inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when seating the insert clamp screw — do not overtighten by feel alone; follow the toolholder documentation. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and geometric accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.10 mm (0.0433 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.30 mm (0.0512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 mm to 2.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.00 mm (0.157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.08 mm (0.0032 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.2717 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.375\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: C\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\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\u003eSeries\u003c\/strong\u003e: CoroThread 266\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 254LG-16CC01-110 1135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 254\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: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5961307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729493688626,"sku":"5961307","price":541.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fac57aa2c577537ba4aefb52849684fc_aae745a5-6851-4af6-8731-37b2214be3bb.jpg?v=1788705263","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5961307-grooving-insert-corothread-266","provider":"Voomi Supply","version":"1.0","type":"link"}
