It is designed for precision internal boring operations on CNC lathes, manual lathes, and boring mills. The minimum bore diameter is 0.29 inches, with a maximum bore depth of 1.1 inches. The shank diameter measures 5\/16 inches and the overall length is 2.5 inches. A bright finish coating reduces friction and helps maintain dimensional accuracy during cutting. This tool is suited for machinists and tool-and-die professionals working to tight tolerances on small-diameter bores in steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-bore internal finishing and semi-finishing applications in both job-shop and production environments. Its submicron carbide grade provides the hardness and edge retention needed for consistent performance on ferrous and non-ferrous workpieces. The left-hand cutting direction makes it appropriate for specific spindle orientations or back-boring operations where a standard right-hand tool cannot be used. Machinists requiring precise bore geometry on small components will find this bar a direct-fit solution.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for back-boring or reverse-spindle applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.29 inches for small-bore precision work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.1 inches\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge and friction\u003c\/li\u003e\n\u003cli\u003eCompact 2.5-inch overall length for use in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling addition for lathes and boring mills accepting a 5\/16-inch round shank boring bar.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Secure the shank firmly in the tool holder to the specified clamping torque listed in the machine documentation, ensuring minimal overhang to reduce vibration. Confirm spindle direction matches the left-hand cutting orientation before engaging the workpiece. Always power down and lock out the machine before changing tooling.\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: 0.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.1 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\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-BBL2901100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746605990194,"sku":"ACC-BBL2901100","price":56.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c617cf948beb4edb597b7db48792d90.jpg?v=1788871698","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl2901100-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
