Manufactured from submicron-grade solid carbide and coated with AlTiN (aluminum titanium nitride), this bar delivers excellent wear resistance and heat dissipation at elevated cutting speeds. It handles a minimum bore diameter of 0.49 inches and a maximum bore depth of 2.6 inches, making it well suited to close-tolerance finish boring in a wide range of workpiece materials including hardened steels and cast iron. The 0.5-inch shank diameter and 4-inch overall length provide rigid tool holding in standard ER or set-screw style boring head holders.\u003c\/p\u003e\u003cp\u003eThis boring bar is appropriate for production and job-shop environments where consistent bore geometry and surface finish are required. Right-hand cutting direction makes it compatible with conventional spindle rotation on most CNC turning and milling platforms. Machinists and tool-and-die professionals working in aerospace, automotive, and general metalworking applications will find this bar fits common finish-boring workflows where carbide rigidity reduces chatter and improves dimensional repeatability. It ships as a single unit and is suited for both new-setup applications and direct replacement of worn tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.49 inches enables work in tight bore profiles\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 2.6 inches handles a broad range of workpiece thicknesses\u003c\/li\u003e\n\u003cli\u003eRight-hand cut matches standard CNC spindle rotation without special setup\u003c\/li\u003e\n\u003cli\u003e0.5-inch shank diameter fits widely available boring head holders and tool blocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling addition for CNC lathes and machining centers accepting a 0.5-inch shank boring bar with right-hand cutting direction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine in a fully powered-down and locked-out state before changing tooling. The shank must be seated to the minimum clamping depth specified by the tool holder manufacturer to ensure rigidity and prevent pullout. Verify bore alignment and runout with a dial indicator before taking finish passes. Consult the machine tool manual and applicable shop safety procedures for torque and clamping requirements specific to the tool holder in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\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: 0.49 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\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 inches x 0.75 inches x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.406 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: B4902600A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730487869746,"sku":"B4902600A","price":125.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/626d2a48afe7be874c28c5e3199166cc_258d093d-e7e1-41b1-812f-31e6baed27b6.jpg?v=1788718337","url":"https:\/\/voomisupply.com\/products\/accupro-b4902600a-boring-bar-0-49-in-min-bore-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
