Built from submicron solid carbide with a bright finish, it delivers the rigidity and edge retention required for tight-tolerance bore work. The bar handles a minimum bore diameter of 0.18 inches and a maximum bore depth of 1.1 inches. With a 1\/4-inch shank diameter and an overall length of 2.5 inches, it fits standard toolholders used on manual and CNC lathes and boring mills. The right-hand cutting direction suits conventional setup configurations. Machinists and toolroom operators select this bar when a controlled corner radius between 0.005 and 0.008 inches is required at the base of a bore.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision machining of small-diameter bores in ferrous and non-ferrous materials where a defined corner radius is part of the finished part print. Typical applications include internal diameter finishing, stepped bore relief cutting, and feature generation in close-tolerance workpieces on CNC turning centers, manual lathes, and jig boring machines. The submicron carbide grade supports use in production environments where consistent tool life and dimensional repeatability are required across multiple parts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.18 inches for small-diameter internal machining\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.1 inches suits a range of through and blind bore applications\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled edge geometry at bore base\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge and aids chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration 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 selection for 1\/4-inch shank boring bar toolholders used on CNC turning centers, manual lathes, and boring mills accepting that shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the 1\/4-inch shank in the appropriate toolholder and verify clamping torque per machine builder specifications before running. Power down and lock out the machine before changing or adjusting the boring bar. Confirm bore diameter and depth clearances against the part program or setup sheet prior to cutting to avoid 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\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: B1801100R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739525054770,"sku":"B1801100R","price":48.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93d7708d918bb25954c3d814f2a4cd55.jpg?v=1788815727","url":"https:\/\/voomisupply.com\/products\/accupro-b1801100r-corner-radius-boring-bar-submicron-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
