Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With six flutes and a right-hand cutting direction, the tool produces smooth bore surfaces in a single pass. Machinists and tool-and-die professionals use this reamer for close-tolerance finishing operations on manual mills, lathes, and CNC drilling centers.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for light industrial and precision machining environments where hole diameter control is critical. Its 1.25-inch flute length handles typical through-hole and shallow blind-hole applications in the 0.2000 to 0.2499 inch diameter range. The 5-inch overall length provides enough reach for most standard fixturing setups without excessive overhang. It is sold individually and is appropriate for job shops, maintenance departments, and production machining operations requiring repeatable finish-reaming results.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2160 inch finished bore diameter with 6 straight flutes for smooth surface finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with 1.25-inch flute length for shallow and through-hole reaming\u003c\/li\u003e\n\u003cli\u003e5-inch overall length for versatile fixturing in manual and CNC applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in the 0.2000 to 0.2499 inch reamer diameter range, compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed and operated by machinists following standard shop practices. Before mounting, ensure the spindle, chuck, or collet holder is fully de-energized and at rest. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout. Always apply an appropriate cutting fluid for the workpiece material and never force the reamer into an undersized pilot hole, as this risks tool breakage and out-of-tolerance bores.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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: 0.15 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: 72021603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747774628146,"sku":"72021603","price":37.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560aeb02ec3ebf33aa2712c4aa7d1f31_ad29c6eb-952e-4ec3-8a6c-664572b59e42.jpg?v=1788885306","url":"https:\/\/voomisupply.com\/products\/hertel-72021603-chucking-reamer-0-2160-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
