It is designed for tight-tolerance internal boring operations on CNC lathes and manual turning centers. The bar handles a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.25 inches, making it suited for small-diameter finish boring where rigidity and edge retention are critical. The 3\/16-inch shank diameter and 2-inch overall length keep the tool compact for confined workpiece bores. The bright finish coating provides a clean surface that resists built-up edge on most workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for production and job-shop machining environments where small-bore precision is required. Typical applications include finishing pre-drilled or rough-bored holes in ferrous and non-ferrous materials on turning equipment. The left-hand cutting direction suits specific spindle orientations or back-boring setups where a standard right-hand bar cannot be used. Machinists and CNC setup technicians working with close-tolerance bore callouts will find the submicron carbide grade appropriate for maintaining dimensional accuracy across repeated passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction provides high hardness and edge retention in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction accommodates back-boring and reverse-spindle setups\u003c\/li\u003e\n  \u003cli\u003e0.14-inch minimum bore diameter enables access to very small internal diameters\u003c\/li\u003e\n  \u003cli\u003e0.25-inch maximum bore depth suits shallow precision bores\u003c\/li\u003e\n  \u003cli\u003eBright finish coating resists built-up edge and simplifies chip evacuation observation\u003c\/li\u003e\n  \u003cli\u003eCompact 2-inch overall length reduces overhang and improves rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar for CNC lathes and manual turning centers accepting a 3\/16-inch round shank tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the shank fully in the tool holder to the manufacturer-recommended clamping depth to minimize deflection during cut. Confirm spindle direction matches the left-hand cutting geometry before engaging the workpiece. Inspect the cutting edge for chips or wear before each setup, as carbide micro-grade tooling is brittle and sensitive to interrupted cuts or improper clamping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 0.25 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\u003eCutting Direction\u003c\/strong\u003e: Left Hand\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-BBL140250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732847198514,"sku":"ACC-BBL140250","price":42.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78465a328e73bffb844f18ad8252c280.jpg?v=1788747482","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl140250-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
