Built to the E12S-SCLCL 3 toolholder style, it features a 3\/4-inch shank diameter, a 10-inch overall length, and a minimum bore diameter of 0.929 inches (23.60 mm). Screw clamping secures a single CCMT 32.52 insert, and coolant-through capability supports consistent chip evacuation in deep-bore applications. The neutral rake geometry and 0-degree rake angle make it suitable for a wide range of workpiece materials. Licensed machinists and CNC operators typically specify this bar for precision internal diameter work requiring tight tolerances.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision machining environments including job shops, production turning cells, and tool rooms. The left-hand cut orientation suits specific spindle rotation and approach directions common in Swiss-style and gang-tool setups. The CoroTurn 107 series is engineered for light to medium cutting depths with CCMT insert geometry, making it a practical choice when bore diameter, surface finish, and tool life consistency are priorities. The 1\/2-inch center-to-cutting-edge dimension and 0.75-inch neck diameter are relevant when planning clearance in close-tolerance bore applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-diameter boring\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.929 inches (23.60 mm) for tight internal feature access\u003c\/li\u003e\n\u003cli\u003eScrew clamping insert retention with CCMT 32.52 insert compatibility\u003c\/li\u003e\n\u003cli\u003eCoolant-through design to support chip control and thermal management\u003c\/li\u003e\n\u003cli\u003eLeft-hand cut orientation for specific approach and spindle configurations\u003c\/li\u003e\n\u003cli\u003eNeutral rake (0-degree) geometry suitable for diverse workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CCMT 32.52 inserts.

The machine spindle must be fully stopped and the turret or tool post locked out before mounting or removing the boring bar. Verify shank clamp torque against the machine tool specification and confirm insert seating before taking a test cut. Follow the insert manufacturer guidance for CCMT 32.52 screw torque values.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.929 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 (254.00 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\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 10 inches (254.00 mm)\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: 0.156 inches (5\/32 inch)\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 Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left 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: E-SCLC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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: 2.2 pounds\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: 5734142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731814220082,"sku":"5734142","price":1681.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53b2ddc7e86a8d39b3532233d15e5d91.jpg?v=1788735218","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5734142-indexable-boring-bar-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
