It cuts right hand and accepts a minimum bore diameter of 0.23 inches, reaching a maximum bore depth of 1.5 inches. The 5\/16-inch shank diameter and 2.5-inch overall length suit compact setups where reach and rigidity both matter. A bright finish coating leaves the carbide substrate exposed for visual inspection and general-purpose use. Machinists and toolroom operators reach for this bar when finishing bored holes that require a controlled corner radius rather than a sharp 90-degree break.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited to light-to-medium internal turning and boring operations on machining centers, CNC lathes, and manual turret lathes. The corner radius range of 0.005 to 0.008 inches makes it applicable wherever a fine, consistent radius blend is required at the bottom corner of a bored feature. It is a practical choice for aerospace, mold, and precision-machining shops working in steel, aluminum, and similar machinable materials where solid carbide rigidity reduces chatter in small-diameter bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction provides high rigidity and wear resistance in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eRight hand cutting direction for standard CNC lathe and boring mill setups\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled blend at bore bottom corners\u003c\/li\u003e\n\u003cli\u003eBright finish coating preserves the carbide surface for general-purpose applications\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter with 2.5-inch overall length fits compact toolholders\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches and maximum bore depth of 1.5 inches define the working envelope\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 5\/16-inch boring bar toolholders used in CNC lathes, machining centers, and manual turret lathes requiring right hand corner radius boring bars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop safety and machine lockout\/tagout procedures before toolholder changes. Ensure the machine spindle is fully stopped and the toolholder bore is clean and free of chips before seating the shank. Confirm shank runout with a dial indicator after clamping to minimize deflection in small-diameter bores. Follow the machine tool manufacturer guidelines for overhang limits and clamping torque on the toolholder set screws.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\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: 1.5 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\u003eCorner Radius Range\u003c\/strong\u003e: 0.005 to 0.008 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\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: B2301500R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741815079218,"sku":"B2301500R","price":60.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/974f69c428d76d16c28298ddda278420.jpg?v=1788833621","url":"https:\/\/voomisupply.com\/products\/accupro-b2301500r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
