It cuts in a right-hand direction and is suited for tight-tolerance bores starting at 0.32 inches in diameter, with a maximum bore depth of 0.75 inches. The 3\/8-inch shank diameter and 2.5-inch overall length make it compatible with standard boring bar holders found in CNC machining centers and manual lathes. The bright, uncoated finish maintains dimensional accuracy straight from the manufacturer. Corner radius range runs from 0.005 to 0.008 inches, making this bar appropriate for finishing passes where edge geometry is critical.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in precision machining environments where small-diameter internal features require a controlled corner radius. It is well suited for shops running ferrous and non-ferrous workpieces that demand consistent surface finish and geometric accuracy in tight bores. The submicron carbide grade provides the hardness and wear resistance needed for finishing and light semi-finishing cuts at close tolerances. Machinists and CNC operators in job shops, production facilities, and tool rooms are the primary users of this bar.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.32 inches allows access to small internal features\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled finish geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard boring setups\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish preserves dimensional tolerances out of the box\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits widely available boring bar holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for 3\/8-inch boring bar holders used in CNC lathes, machining centers, and manual boring setups requiring a corner radius profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's setup procedures. Secure the shank fully within the tool holder to the recommended overhang length to minimize deflection during cutting. Verify spindle and coolant systems are off and the machine is in a safe state before mounting or removing the bar. Do not exceed the rated minimum bore diameter, as doing so may cause tool deflection, chatter, or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.75 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\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\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\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: B320750R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51775003885874,"sku":"B320750R","price":76.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4199b527807177b067374ea7bc0a98a9.jpg?v=1789166123","url":"https:\/\/voomisupply.com\/products\/accupro-b320750r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
