Built from steel with a 3\/8 inch (9.53 mm) shank diameter and a 6 inch (152.40 mm) overall length, this right-hand toolholder accepts CCMT 21.51 inserts secured by screw clamping. The minimum bore diameter is 0.4803 inches (12.20 mm), making it suitable for tight-bore finish work. A neutral rake angle and 0-degree lead angle support consistent chip control across a range of workpiece materials. Coolant-through capability helps manage heat and chip evacuation during deep or interrupted cuts.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for precision internal turning and boring in production and job-shop environments. Its multi-use design supports both boring and turning applications from a single toolholder, reducing setup time when working on through-holes, blind bores, and facing operations. The CoroTurn 107 series is a well-established indexable platform used in light to medium-duty turning applications on lathes and turning centers where consistent insert positioning and quick change capability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRight-hand cut orientation; suitable for standard lathe and turning-center setups\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention for positive, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and thermal management in deep bores\u003c\/li\u003e\n  \u003cli\u003eNeutral rake (0-degree) supports a broad range of insert grades and workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMulti-use toolholder supports both boring and turning from one platform\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch neck diameter matches shank diameter for consistent rigidity along the bar\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts CCMT 21.51 inserts with a 1\/4 inch (6.35 mm) inscribed circle.

Ensure the machine spindle is fully stopped and the turret or toolpost is locked before mounting or removing the toolholder. Confirm insert seating and screw torque per the insert manufacturer guidelines before taking a cut. Verify coolant-through connections are clear and properly pressurized before engaging the coolant supply.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.4803 inches (12.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inch (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 Compatibility\u003c\/strong\u003e: CCMT 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\u003eToolholder Style\u003c\/strong\u003e: A-SCLC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5721753\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728484073778,"sku":"5721753","price":267.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bc2eeb19eafaa34cab9f61a20dd102b.jpg?v=1788691928","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721753-indexable-boring-bar-3-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
