Built from steel with a 1\/2-inch shank diameter and a 6-inch overall length, this right-hand holder accepts CCMT 21.51 inserts secured by screw clamping. The minimum bore diameter is 0.5984 inches (15.20 mm), making it suitable for small-to-medium bore work. The neutral rake geometry and 0-degree lead angle support stable, predictable cutting in a range of materials. This toolholder is handled and set up by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for both boring and turning applications in light to moderate cutting conditions. The CoroTurn 107 series is a widely used Sandvik Coromant platform for positive-insert internal machining. A single insert is used per holder. The coolant-through design allows cutting fluid delivery close to the insert, supporting chip evacuation and tool life in deep-bore and high-speed applications. It is appropriate for use in both production shops and precision machining environments where consistent bore quality is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoroTurn 107 series platform for positive-insert internal turning and boring\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.5984 inches (15.20 mm) for small-bore applications\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability for improved chip evacuation and insert life\u003c\/li\u003e\n  \u003cli\u003eNeutral rake geometry with 0-degree rake and lead angles for stable cutting\u003c\/li\u003e\n  \u003cli\u003eMulti-use design rated for both boring and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept CCMT 21.51 inserts with a 1\/4-inch inscribed circle.

The machine spindle must be fully stopped and the turret locked before changing or indexing the insert. Ensure the shank is clamped squarely in the boring bar holder to the correct overhang for the target bore depth. Follow the machine tool manufacturer and insert manufacturer guidelines for speeds, feeds, and torque when tightening the insert screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: A-SCLC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: A08M-SCLCR 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5984 inches (15.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0000 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 6.0000 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.3120 inches (7.92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CCMT 21.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts Used\u003c\/strong\u003e: 1\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\u003eLead Angle\u003c\/strong\u003e: 0.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring and Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 5721312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728363749682,"sku":"5721312","price":255.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4b12f18a37dd4618780db9ba4a13177.jpg?v=1788690670","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721312-indexable-boring-bar-0-5984-in","provider":"Voomi Supply","version":"1.0","type":"link"}
