It carries insert style R151.2 with a 5.00 mm (0.1969 inch) cutting width and a PVD-applied TiAlN coating that provides heat and wear resistance at the cutting edge. The chipbreaker designation is 4E, the lead angle is 5 degrees right hand, and the relief angle is 7 degrees. A 0.30 mm corner radius gives the edge a controlled geometry suited for consistent chip formation on ferrous and non-ferrous workpieces. This insert is installed by machinists and CNC toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis insert is sized for insert seat size 50 and is held in place by a clamp-style toolholder. It is well suited to high-volume production turning environments where repeatable part-off operations are required. The T-Max Q-Cut system is a common platform in production shops running both manual and automated turning equipment. The manufacturer grade 1125 indicates this insert targets applications where edge toughness and coating performance are priorities. The right-hand orientation means it is intended for conventional right-hand turning setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e5.00 mm cutting width (0.1969 inch) with 4E chipbreaker geometry\u003c\/li\u003e\n\u003cli\u003e5-degree right-hand lead angle with 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003e0.30 mm corner radius for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with insert seat size 50\u003c\/li\u003e\n\u003cli\u003eT-Max Q-Cut series platform for consistent insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification insert for T-Max Q-Cut series clamp-style parting and grooving toolholders that accept insert seat size 50 and the R151.2 insert style.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Shut down spindle rotation and disengage all machine motion before indexing or replacing inserts. Use the correct torque driver or clamping screw to secure the insert in the holder seat — do not over-tighten by hand or with non-specified tools. Verify insert seating and edge orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R151.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max Q-Cut\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: 1125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: 4E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 5.00 mm (0.1969 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 5.00 mm (0.1969 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.30 mm (0.0118 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 5 degrees Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5742389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51735277175090,"sku":"5742389","price":297.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7de06234ada79dd4763aad14ad7b3cf5_55011a13-3aa8-41b3-a11b-63126c255a7a.jpg?v=1788771404","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5742389-cutoff-insert-carbide-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
