This triangular insert features a TiAlN and AlCr2O3 coating applied via PVD process, combining wear resistance with thermal stability for demanding turning operations. The neutral hand orientation and MM chip breaker geometry suit continuous and interrupted cuts on steel and stainless steel. With a 1\/4-inch inscribed circle, a 1\/64-inch corner radius, and a 60-degree included angle, this insert is sized for light-to-medium depth-of-cut passes on CNC lathes and turning centers. Licensed machinists and CNC operators install this insert using the screw-holding method standard to the CoroTurn 107 toolholder system.\u003c\/p\u003e\u003cp\u003eThis insert is designed for primary use on steel workpieces and is also suited for stainless steel, superalloys, and titanium applications. The MM chip breaker geometry is optimized for controlled chip formation during finishing and semi-finishing passes. The CoroTurn 107 series is widely used in production turning environments where consistent insert indexing and repeatable surface finish are required. Three cutting edges per insert are available before replacement, supporting cost-effective tool management in high-volume turning operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN and AlCr2O3 PVD coating for wear resistance on steel and difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eMM chip breaker geometry for controlled chip formation in finishing and semi-finishing\u003c\/li\u003e\n\u003cli\u003e3 cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits both left- and right-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eScrew-holding method provides secure insert clamping and repeatable positioning\u003c\/li\u003e\n\u003cli\u003e60-degree triangle shape (ISO code TCMT 11 03 04-MM 1125) with 7-degree relief angle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroTurn 107 series screw-clamp toolholders accepting TCMT-style triangular inserts with a C clearance code and M tolerance code.

Use the appropriate Torx or hex key torque driver specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the insert or damage the pocket seat. Inspect the insert pocket and screw threads for wear or debris before seating a new insert. Index to an unused cutting edge before replacing the insert entirely to maximize the three available edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN \/ AlCr2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4071 inches (10.34 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (3.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 03 04-MM 1125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 5752476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755834147122,"sku":"5752476","price":264.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aae880ead292da9996004dac94033a5f_fae5e701-ab57-4d06-ab36-23b14578b607.jpg?v=1788960265","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5752476-turning-insert-tcmt221-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
