Built from submicron-grade solid carbide with a bright finish, it delivers consistent cutting performance in small-bore applications. The right-hand cut geometry suits standard CNC and manual boring setups. Minimum bore diameter is 0.16 inches, maximum bore depth is 0.4 inches, and the corner radius range is 0.005 to 0.008 inches. The 3\/16-inch shank diameter and 2-inch overall length make it a compact tool suited for tight internal profiles where dimensional accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments including tool rooms, production shops, and job shops running CNC lathes or manual boring mills. It is well suited for finishing and semi-finishing passes on small internal diameters in ferrous and non-ferrous materials. Machinists and CNC operators working with tight tolerances and small bore geometries will find this bar appropriate for producing controlled corner radii on internal features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut direction for standard boring applications\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled internal profile geometry\u003c\/li\u003e\n\u003cli\u003eBright finish coating with no additional coating buildup affecting dimensions\u003c\/li\u003e\n\u003cli\u003eCompact 2-inch overall length with 3\/16-inch shank for small-bore access\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.4 inches suitable for shallow to moderate internal features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar for standard 3\/16-inch shank toolholders used in CNC lathe and manual boring applications requiring corner radius geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the tool holder bore is clean and within tolerance before seating the 3\/16-inch shank. Secure all set screws to the toolholder manufacturer's specifications before initiating a cut. Verify spindle is fully stopped and machine is in a safe state before any tool change or adjustment.\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: 0.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\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: B160400R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743960596786,"sku":"B160400R","price":58.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc0d711c8aa77ee0f22e021ce1073117.jpg?v=1788851986","url":"https:\/\/voomisupply.com\/products\/accupro-b160400r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
