Machined from submicron-grade solid carbide, it delivers superior rigidity and wear resistance compared to high-speed steel alternatives. The right-hand cutting direction suits standard lathe setups, and the bright finish keeps the tool free of coatings that could affect dimensional tolerances. With a minimum bore diameter of 0.32 inches and a maximum bore depth of 1.5 inches, this bar handles tight-tolerance internal features in a range of workpiece materials. Qualified machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision machining environments where controlled corner geometry is required on internal bores. The 0.005 to 0.008 inch corner radius range allows the operator to achieve specific blend radii at the base of bored features, reducing stress concentrations in finished components. It is commonly used in job shops, aerospace, and general manufacturing applications where solid carbide tooling is specified for hardened or difficult-to-machine materials. The 3\/8 inch shank diameter fits standard boring bar holders designed for that shank size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled internal blend geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and turning center setups\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating interference on dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits common boring bar toolholders\u003c\/li\u003e\n\u003cli\u003eCompact 2.5 inch overall length suits short-reach boring applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boring bar toolholders accepting a 3\/8 inch shank diameter, as found on CNC lathes and manual turning centers configured for solid carbide boring bars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a compatible boring bar holder to the toolholder manufacturer's recommended clamping procedure, ensuring minimal overhang to reduce deflection. Confirm the machine spindle is fully stopped and all energy sources are locked out before mounting or adjusting tooling. Do not exceed the maximum bore depth of 1.5 inches, as this may cause tool deflection or breakage.\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: 1.5 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: 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\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\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 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: B3201500R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739335131442,"sku":"B3201500R","price":75.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/821d0a7e0c12b8a67f78e28525df9c5b.jpg?v=1788813277","url":"https:\/\/voomisupply.com\/products\/accupro-b3201500r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
