It features a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.4 inches, making it well suited for small-diameter, close-tolerance work. The 5\/16-inch shank diameter and 2.5-inch overall length give machinists a compact, rigid tool that minimizes deflection during interrupted or continuous cuts. A bright finish coating is applied to the cutting geometry. This tool is typically installed and used by machinists, toolroom operators, and CNC programmers working in precision metalworking environments.\u003c\/p\u003e\u003cp\u003eThe ACC-BBL2301400 is intended for internal boring applications where a left-hand cutting direction is required, such as back-boring operations or setups where the spindle rotation or tool orientation demands a left-hand geometry. It is suited for production and job-shop environments handling small-bore features in ferrous and non-ferrous workpiece materials. The submicron carbide grade provides enhanced edge stability and wear resistance compared to standard carbide, making it appropriate for finishing passes and tight-tolerance diameter control. Sold individually, it integrates with standard 5\/16-inch boring bar holders and tool blocks common to most turning center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for back-boring and reverse-rotation setups\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches for small-diameter internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.4 inches provides reach for deeper internal passes\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard boring bar holders and tool blocks\u003c\/li\u003e\n\u003cli\u003eBright finish coating on cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/16-inch boring bar holders on CNC lathes and manual turning centers performing left-hand internal boring operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or toolroom technician. Secure the shank firmly in the boring bar holder to the tool block manufacturer's specified clamping torque before engaging the workpiece. Ensure spindle direction and tool orientation are confirmed for left-hand cut geometry before initiating a cut. Inspect the cutting edge for chipping or wear before each use, as carbide tooling can fail without visible warning if overloaded.\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: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 0.125 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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-BBL2301400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739184628018,"sku":"ACC-BBL2301400","price":57.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a11098fde1822c8b7cef5020bc7444f.jpg?v=1788810983","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl2301400-boring-bar-left-hand-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
