Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing in a wide range of metals and plastics. The straight-cylindrical shank seats securely in a drill press chuck, lathe tailstock, or CNC turret, making it a reliable choice for machine shops, maintenance facilities, and production environments. Six right-hand cutting flutes provide smooth material removal and accurate hole geometry on each pass.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for precision hole finishing operations where a drilled hole must be brought to a tight final diameter. It is commonly used in general metalworking, toolroom applications, and maintenance-and-repair contexts where hole roundness, surface finish, and diameter tolerance matter. The 6-inch overall length and 1-1\/2-inch flute length suit through-holes and shallow blind holes in moderate-thickness workpieces. Machinists and tool-and-die technicians are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8.50mm (0.3346 inch) finished hole diameter for precise sizing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across common work materials\u003c\/li\u003e\n\u003cli\u003e6 straight right-hand flutes for smooth cutting action and consistent finish\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — ready to run without additional prep\u003c\/li\u003e\n\u003cli\u003eStandard 6-inch OAL suits drill presses, lathes, and CNC turret applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for use in any machine tool equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the appropriate diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists using a drill press, lathe, or CNC machine. Power down and lock out the machine before mounting or removing the reamer from the chuck. Always run a reamer at lower RPM than the equivalent drill and apply cutting fluid appropriate to the workpiece material. Never rotate a reamer in reverse, as this will dull the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 8.50mm (0.3346 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/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: Straight\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: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SM0500850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692363809074,"sku":"SM0500850","price":26.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13a6a7706b6d96ba9ec8a5722bbca968.jpg?v=1788296788","url":"https:\/\/voomisupply.com\/products\/value-collection-sm0500850-chucking-reamer-8-50mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
