Manufactured from submicron solid carbide, this right-hand cut bar delivers consistent performance in tight-tolerance bores. It accepts a minimum bore diameter of 0.23 inches and handles a maximum bore depth of 0.7 inches. The 5\/16-inch shank diameter and 2.5-inch overall length make it well-suited for CNC lathes and manual turning centers where compact tooling geometry is required. The bright finish coating provides clean chip evacuation and contributes to dimensional accuracy in fine finishing passes. This bar is typically installed by machinists and toolroom operators working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThe B230700R is applied in internal diameter finishing and semi-finishing operations where controlled corner geometry is critical. The corner radius range of 0.005 to 0.008 inches suits applications requiring a defined blend between bore wall and floor surfaces, such as counterbored features, stepped bores, and precision fit cavities. It is appropriate for use in both production machining and prototype work on ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for hardness and wear resistance in demanding bore conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches enables work in small, deep features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.7 inches supports typical through and blind bore applications\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled surface blending at bore transitions\u003c\/li\u003e\n\u003cli\u003eBright finish coating supports chip flow and surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC and manual lathes accepting 5\/16-inch shank boring bars with right-hand cutting geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. The machine spindle must be fully stopped and the tool turret or holder locked before inserting or removing the boring bar. Secure the shank firmly in the boring bar holder to the depth recommended by the holder manufacturer to prevent deflection during cuts. Follow shop safety procedures and applicable OSHA machine guarding requirements when setting up tooling.\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: 0.7 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: 0.005 to 0.008 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: B230700R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740155871538,"sku":"B230700R","price":60.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95be19190e8efc1eb29ed800d9c3276d.jpg?v=1788822973","url":"https:\/\/voomisupply.com\/products\/accupro-b230700r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
