Built from submicron-grade solid carbide with a bright finish, it delivers rigidity and dimensional consistency in tight-tolerance bore work. The bar features a 0.32-inch minimum bore diameter and a 1.6-inch maximum bore depth, making it well-suited for small-diameter, moderate-depth applications. The 3\/8-inch shank diameter and 3-inch overall length fit standard tool holders used in production and job-shop turning environments. Machinists and CNC operators working in ferrous and non-ferrous materials will find this bar a reliable choice for finish boring passes.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for internal diameter finishing and semi-finishing on turning centers where left-hand cutting geometry is required. It is applicable in production machining environments handling small bores in steel, cast iron, aluminum, and similar workpiece materials. The submicron carbide grade provides the hardness and edge retention needed for consistent surface finish results across repeated cycles without regrinding. Typical applications include bore sizing to tight tolerances on small components such as bushings, hydraulic valve bodies, and precision housings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for specific tooling setups requiring reverse rotation or back-boring\u003c\/li\u003e\n\u003cli\u003e0.32-inch minimum bore diameter accommodates small internal features\u003c\/li\u003e\n\u003cli\u003e1.6-inch maximum bore depth supports moderate-depth through and blind bores\u003c\/li\u003e\n\u003cli\u003eBright finish coating on carbide substrate\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits widely available standard boring bar holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application boring bar for turning centers and CNC lathes equipped with 3\/8-inch boring bar tool holders requiring left-hand cut geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of boring bars should be performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and all motion is locked out before mounting or removing tooling. The bar should be clamped securely in a compatible tool holder with minimum overhang to reduce chatter and deflection. Verify cutting direction and rotation of the spindle match the left-hand geometry of this bar before initiating a cut.\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: 0.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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: 0.219 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-BBL3201600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735196533042,"sku":"ACC-BBL3201600","price":77.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/098c182212eb05d61d686e67d7c0ee9a.jpg?v=1788770214","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl3201600-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
