Built from solid carbide, the bar delivers the rigidity and vibration resistance needed for tight-tolerance internal features. It accepts CCMT 32.52 inserts secured by screw clamping, provides a neutral rake angle of 0 degrees, and has a minimum bore diameter of 0.9291 inches (23.60 mm). The 3\/4-inch shank diameter and 10-inch overall length suit a wide range of production and jobshop boring setups where consistent insert indexing and coolant-through capability are priorities.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for machining professionals — machinists, toolroom technicians, and CNC operators — working in ferrous and non-ferrous materials where controlled chip formation and repeatable bore quality are required. The multi-use design supports both boring and turning applications from a single holder. The coolant-through feature directs fluid directly to the cutting zone, making it well suited for deep-bore applications or materials that generate significant heat at the cutting edge. Installation is straightforward in any lathe or machining center with a standard 3\/4-inch boring bar holder or block.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for maximum rigidity and vibration damping in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability directs fluid to the cutting edge for improved tool life and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention provides secure, repeatable seating of CCMT 32.52 inserts\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle (0 degrees) suits a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMulti-use holder supports both boring and turning operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation with 3\/4-inch neck diameter matching the shank diameter for consistent tool setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CCMT 32.52 inserts (3\/8-inch inscribed circle).

Before mounting or insert changes, ensure the machine spindle is in the locked or off state and all motion has stopped. Secure the bar in a 3\/4-inch boring bar holder to the machine manufacturer's recommended clamping torque specification. Connect coolant-through lines if the machine tool and holder support internal coolant delivery, and verify coolant pressure is within the machine and toolholder manufacturer limits before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.9291 inches (23.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CCMT 32.52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inch)\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 Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E-SCLC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 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: 5734143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727400436018,"sku":"5734143","price":1669.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f519f769ae296f8c82690a89ae7f480a.jpg?v=1788677385","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5734143-indexable-boring-bar-3-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
