With a reamer diameter of 0.3122 inches (5\/16 inch nominal) and a diameter tolerance of 0.0002 inches, this tool delivers tight, repeatable bore sizing in a single pass. The 4.610-inch overall length and 1.299-inch flute length make it well suited for through-hole and shallow blind-hole operations. Six flutes with a left-hand spiral and right-hand cutting direction reduce chatter and produce a smooth, accurate finish. It is installed and operated by machinists and toolroom professionals on CNC machining centers and manual drill presses alike.\u003c\/p\u003e\n\u003cp\u003eThis reamer is designed for use in production and job-shop environments where hole diameter accuracy and surface finish are critical. The Series 8600 designation places it within MAGAFOR's standard solid carbide reamer line, appropriate for ferrous and non-ferrous materials where carbide wear resistance outperforms high-speed steel. The straight-cylindrical shank seats directly into standard collet chucks and drill chucks without adapters, making it a straightforward drop-in for most setups requiring a 5\/16-inch finished bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life and dimensional stability in demanding materials\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch diameter tolerance delivers precision bore sizing for close-fit applications\u003c\/li\u003e\n  \u003cli\u003eSix-flute left-hand spiral geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard collet chucks and drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for use in CNC machining centers, manual mills, and drill presses equipped with standard collet or drill chuck tooling that accepts a straight-cylindrical shank in the 5\/16-inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with rotating cutting tools and machine tool safety practices. Always bring the spindle to a complete stop and confirm the machine is in a safe, locked-out state before changing or inspecting the reamer. Secure the straight-cylindrical shank fully within the collet or chuck to the manufacturer-recommended engagement depth before running. Use appropriate cutting fluid or coolant compatible with the workpiece material to extend tool life and maintain bore quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Nominal)\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal)\u003c\/strong\u003e: 0.3122 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MAGAFOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 88860007930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAGAFOR","offers":[{"title":"Default Title","offer_id":67914730209586,"sku":"88860007930","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a68b9fbf2e678b48e843588ed8dab2aa.jpg?v=1791250722","url":"https:\/\/voomisupply.com\/products\/magafor-88860007930-chucking-reamer-5-16-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
