Machined from submicron-grade solid carbide, it offers superior wear resistance and edge retention compared to standard carbide grades. The bar features a right-hand cutting direction, a 3\/8 inch shank diameter, and a 4 inch overall length. The corner radius range of 0.005 to 0.008 inches makes it well suited for applications requiring controlled edge breaks and fine surface finishes on bored features. This tool is typically installed and operated by machinists and CNC turning specialists working in precision component manufacturing.\u003c\/p\u003e\u003cp\u003eThe B3202500R handles a minimum bore diameter of 0.32 inches and a maximum bore depth of 2.5 inches, making it appropriate for small-diameter deep boring work in materials such as steel, aluminum, and other machinable alloys. It is commonly used in job shops, production turning cells, and toolroom environments where tight tolerances and repeatable corner geometry are required. The bright finish coating reduces built-up edge in certain workpiece materials and assists with chip evacuation in confined bore profiles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for extended tool life and edge stability\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC and manual lathe setups\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 2.5 inches for reaching deep features\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eBright finish coating to reduce built-up edge and aid chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit boring bar for tool holders and boring bar sleeves accepting a 3\/8 inch round shank.

Ensure the machine spindle and all axis drives are powered down and locked out before changing tooling. Confirm shank runout and overhang length against the manufacturer or shop standard before commencing a cut. Do not exceed the maximum bore depth rating, as excessive overhang increases vibration and can compromise surface finish and tool integrity.\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: 2.5 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: 4 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: 0.25 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: B3202500R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727141732658,"sku":"B3202500R","price":102.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/768b5ce59938d9f659bf2c827da8864c.jpg?v=1788673942","url":"https:\/\/voomisupply.com\/products\/accupro-b3202500r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
