Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate hole sizing in steel, cast iron, aluminum, and similar materials. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand cutting direction suits standard spindle rotation. With an overall length of 5 inches and a 1-1\/4-inch flute length, the tool is sized for close-tolerance finishing work on manual and CNC machine tools in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for machine shop, toolroom, and maintenance operations where hole diameter tolerance and surface finish are critical. It handles through-hole and blind-hole applications within its 0.2000- to 0.2499-inch diameter range class. Machinists, toolmakers, and maintenance mechanics typically deploy this tool in drill presses, lathes, milling machines, and machining centers when reaming to a final fit diameter. The 6-flute geometry provides smooth cutting action and good chip distribution at moderate feeds and speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2185-inch finish diameter with 6 straight flutes for accurate, smooth hole sizing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eCompact 5-inch OAL suits bench-top and vertical machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in any drill press, lathe, milling machine, or machining center equipped with a chuck or collet capable of gripping a straight-cylindrical shank in the 0.2185-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified maintenance mechanic should install and operate this reamer. Always power down and lock out the machine spindle before mounting or removing the tool. Secure the straight-cylindrical shank firmly in the chuck or collet before initiating a cut, and apply cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Do not use this reamer for stock removal beyond what is needed for finish sizing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2185 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 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\u003eReamer Diameter Range Class\u003c\/strong\u003e: 0.2000 - 0.2499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72021850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744602194226,"sku":"72021850","price":37.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560aeb02ec3ebf33aa2712c4aa7d1f31_50722b78-0604-4994-ae15-8dfe543b044d.jpg?v=1788858865","url":"https:\/\/voomisupply.com\/products\/hertel-72021850-chucking-reamer-0-2185in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
