Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for tight-tolerance bore work in ferrous and non-ferrous materials. With a minimum bore diameter of 0.49 inches and a maximum bore depth of 3 inches, this bar covers a practical range of internal turning applications. The 0.5-inch shank diameter and 6-inch overall length (OAL) make it compatible with standard tooling setups found in production and job-shop environments. Machinists and toolroom technicians will find the bright finish coating appropriate for general-purpose boring where coolant flow and chip evacuation are managed at the machine level.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for left-hand turning applications where the spindle direction or part setup requires a left-hand cutting orientation. Typical use cases include single-pass bore finishing, stepped bore work, and ID turning where a right-hand bar cannot reach or orient correctly. The submicron carbide grade supports both dry and wet cutting conditions and is particularly well suited for achieving consistent surface finish on close-tolerance bores in production environments where tool life consistency matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut orientation for reverse-spindle or specialized boring setups\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.49 inches for small-bore internal turning\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 3 inches for deeper internal reach\u003c\/li\u003e\n\u003cli\u003e0.5-inch shank diameter fits standard boring bar holders and turret tooling\u003c\/li\u003e\n\u003cli\u003eBright finish coating suitable for general-purpose machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 0.5-inch boring bar holders used in CNC turning centers and manual lathes requiring left-hand cut internal boring tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the boring bar holder to the recommended clamping depth before operation. Confirm spindle direction and cutting orientation match left-hand cut requirements before engaging the workpiece. Always follow machine guarding and chip control procedures appropriate to the material being bored.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 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: 0.625 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-BBL4903000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731021758770,"sku":"ACC-BBL4903000","price":141.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/806ca04845188ec0e27a1d1f589f0ec3.jpg?v=1788725962","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl4903000-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
