Built from submicron-grade carbide with a bright finish, this bar delivers consistent cutting performance in tight-tolerance bore work. The 3\/16-inch shank diameter and 2-inch overall length make it well suited for small-diameter bore applications starting at 0.14 inches minimum bore diameter, with a maximum bore depth of 0.4 inches. Machinists and toolroom operators use this bar when high rigidity and dimensional accuracy are required in close-bore finishing passes.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-bore internal turning applications in production and toolroom environments. Its submicron carbide construction handles a range of workpiece materials where tool deflection and wear resistance are critical. The left-hand cutting direction suits specific lathe setups and back-boring configurations where a right-hand tool cannot be used. It ships individually and is appropriate for job shops, production turning cells, and precision machining operations requiring consistent results in small-diameter bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance in precision boring\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for specialized lathe setups and back-boring applications\u003c\/li\u003e\n\u003cli\u003e0.14-inch minimum bore diameter allows work in very small internal features\u003c\/li\u003e\n\u003cli\u003e0.4-inch maximum bore depth suited to shallow to moderate internal passages\u003c\/li\u003e\n\u003cli\u003eBright finish coating on the shank and body\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter with 2-inch overall length for compact toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring bar for toolholders accepting a 3\/16-inch shank diameter in standard CNC and manual turning center setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolroom procedures. Secure the shank fully in the toolholder to the recommended clamping depth to minimize overhang and reduce deflection. Power down the machine and verify spindle stop before changing tooling. Follow the machine manufacturer guidelines for feed rate, speed, and coolant application when setting up carbide boring bars.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACC-BBL140400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732777632050,"sku":"ACC-BBL140400","price":48.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bbf18fb60fc23aef4563470aa95b10f_842afe35-273d-4473-a952-97314288ce4f.jpg?v=1788746691","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl140400-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
