It belongs to the CoroTurn 107 series and accepts TCMT 21.51 inserts, making it a go-to toolholder for precision bore finishing on CNC lathes and turning centers. The cartridge has a right-hand cutting direction and a minimum bore diameter of 0.5906 inches (15.00 mm). With a toolholder style designation of STFCR and a package weight of 0.13 pounds, this cartridge is suited for machinists and toolroom professionals performing tight-tolerance internal diameter work on a range of materials.\u003c\/p\u003e\u003cp\u003eThis cartridge is designed for boring applications where consistent insert indexing and secure clamping are required. It is used in production and job-shop environments on CNC turning centers handling small to medium bore diameters. The CoroTurn 107 series is a common platform in shops running TCMT-style inserts, and the 5751123 fits directly into that tooling system. Typical applications include finish boring of housings, bushings, and hydraulic components where bore geometry and surface finish tolerances are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.5906 inches (15.00 mm) for small-bore internal turning\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003eCompatible with TCMT 21.51 insert style for broad insert availability\u003c\/li\u003e\n\u003cli\u003eSTFCR toolholder style designation for consistent setup and replacement\u003c\/li\u003e\n\u003cli\u003ePart of the CoroTurn 107 series, a widely used indexable boring platform\u003c\/li\u003e\n\u003cli\u003eCompact cartridge form factor at 3.27 inches length, 1.18 inches height, and 1.18 inches width\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with TCMT 21.51 inserts.

Power down and lock out the machine spindle before cartridge installation or insert indexing. Follow the machine tool manufacturer guidelines and the toolholder manufacturer torque specifications for clamping screws when seating the cartridge and securing the insert. Verify bore diameter clearance and overhang before engaging the workpiece to avoid interference or chatter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Application\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: STFCR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5906 inches (15.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Insert Compatibility\u003c\/strong\u003e: TCMT 21.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291900\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: 5751123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732390445362,"sku":"5751123","price":321.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/565a278ddf5f71b5946add44d87e163a.jpg?v=1788742328","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5751123-indexable-boring-cartridge","provider":"Voomi Supply","version":"1.0","type":"link"}
