Built from solid carbide, this right-hand-cut toolholder carries a single TCMT 21.51 insert secured by screw clamping, delivering rigid, repeatable positioning on each insert change. The 1\/2-inch shank diameter and 8-inch overall length suit it for reaching into deep-bore workpieces while maintaining the stiffness needed to hold tolerance. Minimum bore diameter is 0.6236 inches (15.84 mm), making it appropriate for small-to-medium diameter internal features requiring precise finish cuts.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is part of the Sandvik Coromant CoroTurn 107 series, engineered for both boring and turning applications in production and job-shop environments. It is suited for use on medium-to-hard workpiece materials where a neutral rake geometry and precise insert positioning are required. The coolant-through design channels cutting fluid directly to the insert tip, supporting chip evacuation and tool life in deep-bore or interrupted-cut conditions. Machinists and CNC programmers in metalworking, aerospace, automotive, and general machining shops will find it appropriate for finishing and semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and vibration resistance in small-diameter boring applications\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability delivers fluid directly to the cutting zone for improved chip control and insert life\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention ensures repeatable edge positioning and quick insert indexing\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle (0 degrees) and 0-degree lead angle support stable cutting across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with TCMT 21.51 inserts with a 0.225-inch (5.71 mm) inscribed circle for fine-detail bore finishing\u003c\/li\u003e\n  \u003cli\u003eMulti-use toolholder accepts both boring and turning operations, reducing tooling inventory requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TCMT 21.51 series inserts.

Before mounting or changing inserts, ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state per shop safety procedures. Verify shank bore and clamping set screw torque against the machine tool manufacturer specifications before running. Always confirm insert seating and screw engagement before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.6236 inches (15.84 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches (203.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 8 inches (203.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.312 inches (7.92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.225 inches (5.71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TCMT 21.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right 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 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts Used\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: C-STFC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.71 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: 5726646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748697276722,"sku":"5726646","price":944.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69380beb017382c7935afacbd5ef7b11_3729a0ca-ebd6-4a7b-935e-b4cedbbd794d.jpg?v=1788896909","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5726646-indexable-boring-bar-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
