Built from submicron solid carbide, this right-hand-cut bar delivers the rigidity and wear resistance required for precision work in small-diameter bores. It accepts a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 1.8 inches. The bright finish coating reduces friction and aids chip evacuation. With a 3\/8-inch shank diameter and an overall length of 3 inches, this tool fits a range of standard boring bar holders used by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision internal boring in CNC and manual lathe applications where a controlled corner radius is required. The corner radius range of 0.005 to 0.008 inches makes it appropriate for finishing passes and applications demanding tight dimensional tolerances. It is commonly used in job shops, production machining environments, and tool rooms handling close-tolerance components in steel, cast iron, and similar materials. The right-hand cutting direction is standard for conventional boring setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.32 inches for small-bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.8 inches\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for finish-quality results\u003c\/li\u003e\n\u003cli\u003eBright finish coating to reduce friction and aid chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard boring bar holder setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling addition for standard 3\/8-inch shank boring bar holders used in CNC and manual lathe boring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar is installed and serviced by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping requirements. Verify bore alignment and runout before taking finish passes to avoid tool deflection or chatter.\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: 0.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.8 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\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: 0.219 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: B3201800R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741110141234,"sku":"B3201800R","price":75.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30c37ab850cc1a9132268afa02d8d4f6.jpg?v=1788829396","url":"https:\/\/voomisupply.com\/products\/accupro-b3201800r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
