With a reamer diameter of 0.4355 inches and a right-hand spiral flute configuration, this tool delivers accurate, smooth bores in drilled holes that require tight dimensional tolerances. The straight-cylindrical shank mounts directly into a drill chuck or collet on a lathe, drill press, or CNC machine. Six flutes distribute cutting load evenly and help maintain roundness and finish quality. The bright, uncoated HSS construction suits general-purpose ferrous and non-ferrous materials. This is a dowel pin reamer sized to 0.4355 D\/P, making it appropriate for applications where precise pin-fit holes are required.\u003c\/p\u003e\u003cp\u003eThis reamer is used in machine shop, toolroom, and production environments where holes must be brought to a final, precise diameter after drilling. The 5-1\/2 inch overall length and 1-3\/4 inch flute length accommodate typical workpiece depths encountered in general machining work. It is suited for use on manual lathes, drill presses, and CNC equipment. Machinists and tool-and-die professionals installing dowel pins or fitting close-tolerance cylindrical features will find this size appropriate for 0.4355-inch nominal pin fits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.4355 inch reamer diameter matched to 0.4355 D\/P dowel pin specification\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness for general-purpose ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes — 6 total — for smooth cutting action and even chip load distribution\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003e5-1\/2 inch overall length with 1-3\/4 inch flute length for typical workpiece depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill chucks and collets on lathes, drill presses, and CNC machining centers that accept straight-cylindrical shank tooling in this diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified toolroom operator should install and operate this reamer. Always secure the shank fully in the chuck or collet before operation, and ensure the machine spindle is at the correct RPM for the material being reamed. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Never ream a hole that has not been pre-drilled to the proper undersize diameter, as reaming from solid stock will damage the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4355 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/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\u003eTool Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDowel Pin Size\u003c\/strong\u003e: 0.4355 D\/P\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: 72296635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733399142706,"sku":"72296635","price":79.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61b2d3eb40550056a09a0666151d5fae_86981619-bb49-4c17-8b96-f8830cd305fd.jpg?v=1788755178","url":"https:\/\/voomisupply.com\/products\/hertel-72296635-chucking-reamer-0-4355-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
