Manufactured from submicron-grade carbide with a bright finish, it delivers tight tolerances and consistent surface finishes in small-bore applications. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1.6 inches. With a 5\/16-inch shank diameter and an overall length of 3 inches, this bar is suited for close-quarter setups where rigidity and dimensional accuracy are critical. Machinists and tool-and-die professionals rely on carbide boring bars like this for high-repeatability work in steel, cast iron, and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production machining and job-shop environments where left-hand cutting orientation is required, typically when boring from right to left or when toolpost orientation demands it. It fits toolholders sized for a 5\/16-inch shank and is appropriate for small-bore finishing and semi-finishing passes. The 1.6-inch maximum depth-to-diameter ratio makes it well suited for shallow-to-moderate depth bores where chatter control and tool rigidity are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches for tight, small-bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.6 inches for shallow-to-moderate boring passes\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-orientation toolpost setups\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright finish coating for clean chip evacuation and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders with a 5\/16-inch shank bore; suitable for CNC and manual lathes requiring left-hand internal boring capability in small-diameter applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with boring bar setup on lathes. Ensure the machine is fully powered down and the spindle is locked before mounting or adjusting the boring bar in the toolholder. Set overhang to the minimum length required to reach bore depth to maximize rigidity and minimize deflection. Verify cutting direction and toolholder orientation match the left-hand specification before beginning any 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: 0.23 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: 0.3125 inches (5\/16 inch)\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: 0.125 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-BBL2301600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731491160370,"sku":"ACC-BBL2301600","price":69.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6744c0a648ce27fe307e1fedcd031fdb.jpg?v=1788731710","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl2301600-boring-bar-left-hand-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
