It cuts right-hand direction and accepts a minimum bore diameter of 0.2 inches, reaching a maximum bore depth of 1-13\/64 inches (1.2 inches decimal). The 1\/4-inch shank diameter and 2-1\/2-inch overall length make it well-suited for small-bore work where rigidity and dimensional accuracy are critical. The bright finish coating is applied without additional surface treatment that could alter edge geometry. Machinists and toolroom professionals use this bar when tight corner radii and fine surface finishes are required on internal diameters.\u003c\/p\u003e\u003cp\u003eThis boring bar is designed for small-diameter internal turning and finishing passes in ferrous and non-ferrous materials. It is a practical choice for production machining environments, toolroom setups, and job-shop applications where bore diameter tolerances are tight and corner geometry must be held consistently. The corner radius range of 0.005 to 0.008 inches suits applications requiring a defined, controlled edge break at the bore floor or shoulder transition rather than a sharp corner.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for improved wear resistance and edge stability in small-bore applications\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled shoulder and floor geometry\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.2 inches with maximum bore depth of 1-13\/64 inches\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter for compatibility with standard small-bore toolholders\u003c\/li\u003e\n\u003cli\u003e2-1\/2-inch overall length balances reach and rigidity in tight bore conditions\u003c\/li\u003e\n\u003cli\u003eBright finish coating preserves dimensional accuracy of the cutting edge without added coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard toolroom boring bar for use in right-hand internal boring operations requiring a 1\/4-inch shank and a minimum bore diameter of 0.2 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist familiar with toolholder torque requirements and boring bar overhang guidelines. Secure the shank firmly in the toolholder to minimize deflection and chatter, particularly at maximum bore depth. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore diameter and depth settings with appropriate gauging before committing to a finish pass.\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: 0.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1-13\/64 inches (1.2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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: 0.0625 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: B2001200R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739753611570,"sku":"B2001200R","price":43.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29ea3ba09b5371f340f4f07cf5d0fe2d.jpg?v=1788818517","url":"https:\/\/voomisupply.com\/products\/accupro-b2001200r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
