With a reamer diameter of 0.4995 inches and an overall length of 8 inches, this tool provides accurate sizing in through-holes and blind holes where tight tolerances are required. The bright, uncoated finish is standard for cobalt steel reamers intended for use on a wide range of ferrous and non-ferrous materials. Machinists and toolroom operators use this reamer in CNC machining centers, manual lathes, and drill presses where a chuck-held, straight-shank tool is the correct setup.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production and toolroom environments requiring consistent hole sizing to near-finish tolerances. The 2-inch flute length accommodates typical stock removal depths for this diameter range. The straight-cylindrical shank seats directly in a drill chuck or collet without the need for a taper adapter, making it straightforward to mount in standard machine tool spindles. It is classified as a dowel pin reamer, meaning it is ground to produce holes compatible with standard dowel pin fits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction provides heat resistance and edge retention compared to standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry suited for finishing holes in most ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003e0.4995 inch diameter ground for close-tolerance hole finishing within the 0.4000 to 0.4999 inch range\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without a taper adapter\u003c\/li\u003e\n\u003cli\u003eDowel pin reamer classification for holes requiring dowel pin compatible fits\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — ready to use as ground, with no coating buildup affecting diameter accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in CNC machining centers, manual lathes, and drill presses equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.4995 inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified toolroom operator should install and operate this reamer. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and ensure the machine spindle is stopped and locked before making any tool changes. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality. Follow shop-specific feeds and speeds for cobalt steel reamers at this diameter; consult tooling reference tables rather than applying drill-speed values directly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.4000 to 0.4999 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\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 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: 72556509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749690573106,"sku":"72556509","price":113.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c0619fafccfe259d61ac48401aa0d8d_121b2936-6e72-4d67-a6f6-7403dfad9b94.jpg?v=1788909254","url":"https:\/\/voomisupply.com\/products\/hertel-72556509-chucking-reamer-0-4995-in-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
