With a 0.4980 inch cutting diameter, 8 inch overall length, and 2 inch straight flute length, this reamer is built to hold tight tolerances in ferrous and difficult-to-machine materials. The cobalt steel construction provides heat resistance and wear durability beyond standard high-speed steel tooling. A bright, uncoated finish allows for easy inspection of the cutting edges. This tool is intended for use by machinists and tool-and-die professionals operating CNC or manual lathes, mills, and drill presses.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production reaming operations where consistent hole diameter and surface finish are required. The straight-cylindrical shank allows secure mounting in standard drill chucks, collets, and floating holders. Its right-hand cutting direction and straight flute geometry make it appropriate for through-holes and blind holes in steel, cast iron, and similar materials. The dowel pin reamer designation indicates suitability for finishing holes to receive dowel pins with close-tolerance fits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.4980 inch cutting diameter for close-tolerance hole finishing\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e6 straight flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003e2 inch flute length provides adequate chip clearance in typical through-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows visual edge inspection\u003c\/li\u003e\n\u003cli\u003eDesignated as a dowel pin reamer for precision fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a chucking reamer for use in standard drill chucks, collets, and floating reamer holders accepting a straight-cylindrical shank at 0.4980 inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Use adequate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Do not exceed the recommended feed and speed parameters for cobalt steel tooling in the material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4980 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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 72556491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51983027568946,"sku":"72556491","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acab5d520777aa0c60a932f66ce96a62_36082dbd-3ba9-409e-bfca-ec1bd4de6900.jpg?v=1789983450","url":"https:\/\/voomisupply.com\/products\/hertel-72556491-chucking-reamer-0-4980-in-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
