Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance bores. The bar handles a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.7 inches. With a 3\/16-inch shank diameter and a 2-inch overall length, this compact tool fits small-bore applications where rigidity and accurate tool positioning are critical. The bright finish coating reduces friction and aids in chip evacuation during the cut.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision machining environments including job shops, production turning cells, and toolroom operations. It is well matched for applications requiring left-hand cutting direction, such as back-boring or non-standard spindle-rotation setups. The submicron carbide grade supports use in ferrous and non-ferrous materials where surface finish and dimensional accuracy are priorities. Machinists and CNC operators working on small-bore components will find the 0.14-inch minimum diameter capability useful for fine internal features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for back-boring and reverse-rotation applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.14 inches for small internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.7 inches\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces friction and aids chip flow\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter and 2-inch overall length for compact tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling addition compatible with boring bar holders and cartridges accepting a 3\/16-inch round shank, on CNC lathes or manual turning centers requiring left-hand cut boring tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the shank firmly in the boring bar holder or turret tooling block before operation, and verify tool overhang does not exceed manufacturer recommendations for the holder. Ensure the machine spindle is fully stopped and the control is in an appropriate safe state before tool changes. Follow shop safety procedures and applicable OSHA machining guidelines when handling carbide 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: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\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-BBL140700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752229404978,"sku":"ACC-BBL140700","price":38.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f58cec837db0676b6a93a8ef84122dd.jpg?v=1788926796","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl140700-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
