Manufactured from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance required for tight-tolerance bores. It handles a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 2.6 inches, making it suitable for moderate-depth finishing passes. The right-hand cutting direction and bright finish coating are standard for this tool class. A corner radius range of 0.005 to 0.008 inches allows machinists to produce controlled edge breaks at the base of bored features.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments including job shops, production floors, and tool rooms. It is suited for finishing or semi-finishing internal diameters in ferrous and non-ferrous workpiece materials where a controlled corner radius is required at the bore shoulder. The 0.5-inch shank diameter fits standard boring bar holders and quick-change toolpost systems commonly found on production lathes. It is installed by machinists and CNC operators working in metalworking and industrial manufacturing applications.\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\u003eMinimum bore diameter of 0.49 inches for small-to-mid-range internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 2.6 inches for moderate-depth passes\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for consistent shoulder geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating with 0.5-inch shank diameter for broad holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 0.5-inch boring bar holders used on CNC and manual lathes in metalworking applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Secure the shank fully in the boring bar holder and torque the clamping screws per the holder manufacturer's specifications. Ensure the machine spindle is fully stopped and the lathe is powered down before changing or adjusting tooling. Verify tool overhang does not exceed recommended values for the shank diameter to prevent chatter and deflection.\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: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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 Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.40625 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: B4902600R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67589619089714,"sku":"B4902600R","price":119.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1763721228d2a946cf01ebc777cd4458.jpg?v=1790419181","url":"https:\/\/voomisupply.com\/products\/accupro-b4902600r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
