Machined from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance bore work. The bar handles a minimum bore diameter of 0.29 inches and reaches a maximum bore depth of 1.5 inches. With a 5\/16-inch shank diameter and an overall length of 2.5 inches, it fits standard toolholders common in small-part turning applications. The bright finish reduces friction at the cutting edge and aids chip evacuation. This tool is typically installed by machinists and toolroom operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for small-diameter internal boring in both ferrous and non-ferrous materials where dimensional accuracy is critical. The right-hand cutting direction makes it compatible with conventional lathe spindle rotation. Typical applications include finishing bores in hydraulic components, pump housings, fittings, and precision mechanical assemblies where surface finish and roundness tolerances are tight. Its compact geometry allows access to shallow bores that larger tooling cannot reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.29 inches enables work on small internal diameters\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1.5 inches suits a range of shallow to moderate-depth applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch shank diameter fits standard boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003eBright finish reduces built-up edge and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for use with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment boring bar for toolholders accepting a 5\/16-inch shank diameter on CNC or manual turning centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Before mounting, confirm the toolholder bore and set screw configuration match the 5\/16-inch shank diameter. Secure the bar with the minimum recommended shank engagement to control overhang and reduce chatter. Always power down and lock out the machine spindle before inserting or removing cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\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: Right 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: 0.125 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-BB2901500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734718710066,"sku":"ACC-BB2901500","price":62.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a415cdc296f25f3c385c79bc4c61174.jpg?v=1788765879","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb2901500-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
