With a reamer diameter of 0.4995 inches and a diameter tolerance of 0.0000 to 0.0003 inches, it delivers tight, repeatable sizing suited for dowel pin fits and close-tolerance bores. The 4-inch overall length and 1.5-inch flute length make it practical for general-purpose chuck-mounted reaming on manual lathes, mills, and CNC machining centers. A bright, uncoated finish is standard. Right-hand cutting direction. This tool is typically installed and used by machinists and tool-and-die professionals working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for finishing pre-drilled or bored holes to a precise diameter in ferrous and non-ferrous materials. The straight flute geometry and straight cylindrical shank allow straightforward setup in standard chucks or collets. The 0.4995-inch diameter designates it as a dowel pin reamer, matched to 0.4995 D\/P sizing. It is appropriate for applications where hole roundness, straightness, and surface finish are critical, such as fixture building, die work, and precision assembly operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.4995-inch diameter with 0.0000 to 0.0003-inch tolerance for close-tolerance dowel pin fits\u003c\/li\u003e\n  \u003cli\u003e6-flute straight design promotes consistent chip evacuation and smooth bore finish\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for conventional spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in manual or CNC lathes, knee mills, and machining centers equipped with standard chuck or collet toolholding systems accepting a straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using a standard chuck or precision collet. Ensure the shank is fully seated and concentric before operation to avoid bellmouthing or oversizing the bore. The workpiece hole should be pre-drilled or bored to the appropriate undersize before reaming. Follow shop-standard speeds and feeds for solid carbide reamers based on workpiece material; do not use cutting parameters intended for high-speed steel tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4995 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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 Size\u003c\/strong\u003e: 0.4995 D\/P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 79890117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728606626098,"sku":"79890117","price":310.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a56c2ed3953e09c29a765df435a333fd.jpg?v=1788693895","url":"https:\/\/voomisupply.com\/products\/hertel-79890117-chucking-reamer-0-4995-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
