Designed for right-hand cutting, it accepts a 5\/16-inch shank diameter and delivers a minimum bore diameter of 0.23 inches with a maximum bore depth of 0.5 inches. The corner radius range of 0.0050 to 0.0080 inches allows machinists to produce controlled radii at the base of bored features. The bright finish coating reduces friction and aids chip evacuation. Overall length is 2.5 inches. This bar is suited for tight-tolerance work in production machining and toolroom environments where submicron carbide grade is required to maintain edge integrity at small diameters.\u003c\/p\u003e\u003cp\u003eThe B230500R is used in CNC machining centers, manual boring mills, and toolroom lathes for internal diameter finishing and radius corner work. Its compact geometry makes it well-suited for shallow-cavity boring in hardened steels, stainless alloys, and cast materials where a standard high-speed steel bar would deflect or chip. Machinists working on precision fixture components, hydraulic valve bodies, and small-diameter port work will find the submicron carbide substrate appropriate for consistent, repeatable results in short-run and production applications alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide substrate provides high hardness and wear resistance at small bore diameters\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC and manual boring setups\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.0050 to 0.0080 inches for controlled base-of-bore geometry\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces cutting friction and aids chip flow\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard boring bar holders and quick-change tooling systems\u003c\/li\u003e\n\u003cli\u003e2.5-inch overall length keeps overhang minimal, limiting deflection in shallow-bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit boring bar for standard 5\/16-inch boring bar holders used in CNC machining centers and manual lathes requiring right-hand internal cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool turret or boring head is locked before inserting or removing the bar. Secure the shank firmly in the holder to the manufacturer-specified clamping torque for the holder type in use. Verify bore alignment and runout before engaging the cut to protect the carbide edge from chipping due to misalignment.\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\u003eCutting Direction\u003c\/strong\u003e: Right 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: 0.5 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\u003c\/strong\u003e: 0.0050 to 0.0080 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: B230500R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739769831730,"sku":"B230500R","price":60.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/601ae146e75551379eed6e2668416ca0.jpg?v=1788818660","url":"https:\/\/voomisupply.com\/products\/accupro-b230500r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
