Built from submicron solid carbide with a bright finish coating, this bar delivers tight tolerances and consistent performance in demanding shop environments. It cuts right hand, features a minimum bore diameter of 0.23 inches, and reaches a maximum bore depth of 1.25 inches. The 5\/16-inch shank diameter and 2.5-inch overall length make it well suited for small-bore work where rigidity and tool control are critical. Machinists and toolroom professionals install this type of boring bar on CNC lathes, manual lathes, and boring mills.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision turning and boring operations where corner radius geometry is required at the base of a bored feature. It is suited for both production and prototype machining in job shops, tool rooms, and manufacturing facilities. The corner radius range of 0.005 to 0.008 inches provides a controlled blend at the bore floor, reducing stress concentration and meeting close-tolerance drawing callouts. Applications include finishing passes on steel, aluminum, and other machinable alloys in small-diameter bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches enables work in tight, small-bore features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.25 inches suitable for through and blind bore finishing\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for precise radius blending at bore floor\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces friction and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight hand cutting direction for standard lathe and boring mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for right-hand boring bar holders accepting a 5\/16-inch shank diameter on CNC and manual lathes or boring mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in a compatible boring bar holder and verify runout before cutting. Power down and lock out the machine spindle before setting or adjusting the tool. Do not exceed the recommended overhang ratio for the shank diameter, as excessive overhang on solid carbide bars increases the risk of chipping or breakage.\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: 1.25 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\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: B2301250R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741116662066,"sku":"B2301250R","price":60.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75ada20cf13c81ac82d2059e501734e3.jpg?v=1788829434","url":"https:\/\/voomisupply.com\/products\/accupro-b2301250r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
