Built from cobalt steel with a bright, uncoated finish, it delivers the hardness and heat resistance needed for demanding production and maintenance reaming in steel, cast iron, and similar ferrous materials. The six-flute spiral design in a right-hand cutting direction improves chip evacuation and surface finish compared to straight-flute alternatives. With an 8-inch overall length and a 2-inch flute length, it fits standard drill chucks and collet holders in both manual and CNC machine tool setups. Machinists and tool-and-die professionals are the primary installers of this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for general-purpose hole finishing in job shop, maintenance, and light production environments. Its straight-cylindrical shank allows direct mounting in drill press chucks, milling machine collets, and lathe tailstock chucks without an adapter. The cobalt steel construction makes it appropriate for harder workpiece materials where high-speed steel tooling wears prematurely. It is not an over- or under-size reamer, meaning it is ground to the nominal 31\/64-inch dimension for standard tolerance holes. Typical applications include bearing seat preparation, dowel pin holes, and close-tolerance bore finishing where a drilled hole requires final sizing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for improved hardness and heat resistance over standard HSS reamers\u003c\/li\u003e\n  \u003cli\u003eSix spiral flutes with right-hand cutting direction for efficient chip evacuation and improved hole finish\u003c\/li\u003e\n  \u003cli\u003eNominal 0.4844-inch (31\/64 inch) reamed diameter for standard tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits drill chucks, collet holders, and tailstock chucks without adapters\u003c\/li\u003e\n  \u003cli\u003e8-inch overall length provides clearance for deep setups and through-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight-shank chucking reamer compatible with drill presses, milling machines, lathes, and CNC machining centers equipped with drill chucks or collet systems sized for a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed and operated by machinists following standard machine shop practices. Always secure the shank fully in the chuck or collet and confirm runout before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never use a reamer to remove more stock than the tool geometry is rated for — pre-drill or bore the hole to within standard reaming allowance before running the reamer through.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 31\/64 inches (0.4844 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral 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: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.04 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SM1500031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720552808754,"sku":"SM1500031","price":46.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df99a1cbe28da669e5d472f748bd1fec_961e7f99-3910-40e5-976c-2257f199821a.jpg?v=1788565999","url":"https:\/\/voomisupply.com\/products\/value-collection-sm1500031-chucking-reamer-31-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
