Manufactured from submicron solid carbide with a bright finish coating, it delivers superior wear resistance and edge retention compared to standard carbide grades. The right-hand cut geometry suits conventional CNC and manual boring setups. With a minimum bore diameter of 0.32 inches and a maximum bore depth of 1.6 inches, this bar handles tight-tolerance bores in a wide range of workpiece materials. A 3\/8-inch shank diameter and 3-inch overall length make it compatible with standard boring bar holders found in most machine shops.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for use in CNC machining centers, CNC lathes, and manual boring mills where corner radius control is required on internal features. The 0.0050 to 0.0080 inch corner radius range allows machinists to produce clean, controlled radii at the base of bored features, reducing stress concentrations in finished parts. It is a practical choice for job shops and production environments working in steel, cast iron, aluminum, and similar machinable materials where dimensional accuracy and surface finish are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for extended tool life and consistent edge performance\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard bore orientation in CNC and manual setups\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.0050 to 0.0080 inches for controlled internal radii\u003c\/li\u003e\n\u003cli\u003eBright finish coating  -  no coating buildup that can affect critical bore tolerances\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits standard boring bar holders and tool blocks\u003c\/li\u003e\n\u003cli\u003e3-inch overall length with 1.6-inch maximum bore depth suits a wide range of workpiece depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 3\/8-inch boring bar holders used in CNC turning centers, machining centers, and conventional boring setups requiring corner radius geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with boring bar setup and tool holding practices. Secure the shank firmly in the tool holder to the recommended clamping depth to minimize overhang and reduce chatter risk. Power down and lock out the machine spindle before inserting or removing the boring bar. Verify bore diameter and depth clearance before initiating a cut to prevent tool or workpiece damage.\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: 0.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Range\u003c\/strong\u003e: 0.0050 to 0.0080 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: 0.219 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: B3201600R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743364907314,"sku":"B3201600R","price":75.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddc88ce28f05f86f3023bca666893a06.jpg?v=1788846205","url":"https:\/\/voomisupply.com\/products\/accupro-b3201600r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
