Built from submicron-grade solid carbide with a bright finish, it delivers tight dimensional control at small bore diameters. The minimum bore diameter is 0.32 inches, with a maximum bore depth of 1 inch. The 3\/8-inch shank diameter keeps the bar rigid in the tool holder, and the 2.5-inch overall length suits compact tooling setups. Left-hand cutting geometry makes this bar suitable for back-boring operations or reverse-rotation machining strategies. Machinists and CNC operators working with small-bore, close-tolerance applications will find this bar appropriate for their work.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for small-diameter internal turning on CNC lathes, manual lathes, and horizontal machining centers. Left-hand cut orientation is used when the tool must traverse in the opposite direction from a standard right-hand bar, commonly encountered in back-boring or specific fixturing configurations. The 0.32-inch minimum bore capability makes it appropriate for tight-bore workpieces where standard indexable boring heads cannot reach. This bar fits tool holders accepting a 3\/8-inch round shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for hardness and wear resistance in demanding boring applications\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.32 inches for small-bore, close-tolerance internal operations\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1 inch suitable for through and blind bore configurations within reach\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction for back-boring or reverse-rotation setups\u003c\/li\u003e\n  \u003cli\u003eBright finish coating  -  no additional coating buildup that could affect shank fit tolerances\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter with 2.5-inch overall length for compact tool station use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or supplemental boring bar for tool holders accepting a 3\/8-inch round shank; verify bore diameter range and cutting direction requirements before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis boring bar is installed and serviced by machinists and CNC setup technicians. Power down or E-stop the machine and confirm the spindle is fully stopped before changing tooling. Secure the shank in the tool holder to the manufacturer-specified clamping torque for the holder being used  -  do not over-extend the bar beyond the supported overhang recommended for the holder. Confirm left-hand spindle rotation or back-bore cycle programming before engaging the cut to avoid tool crash or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 0.1875 pounds\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-BBL3201000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67639706550578,"sku":"ACC-BBL3201000","price":78.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbd9070692426469f99df9924a4259fe.jpg?v=1790454315","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl3201000-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
