Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent hole sizing and smooth surface finish in a wide range of workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With 4 right-hand cutting flutes and a 0.75-inch flute length, it removes minimal stock while holding tight dimensional tolerances. It is suited for machine-shop use in manual mills, drill presses, and CNC equipment running at controlled feeds and speeds.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for close-tolerance through-hole and blind-hole finishing operations in production and job-shop environments. The 0.0845-inch diameter falls within the 0.0500 to 0.0999-inch decimal-inch reamer range, making it appropriate for small-bore work in precision components such as pins, dowels, and fastener clearance holes. The 3-inch overall length provides adequate reach for shallow workpieces without sacrificing rigidity. Machinists and tool-and-die professionals typically select this tool when a drilled hole requires a final pass to achieve press, slip, or locational fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0845-inch reaming diameter for precise small-bore finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for general-purpose machining across a broad material range\u003c\/li\u003e\n\u003cli\u003e4 straight right-hand cutting flutes for smooth stock removal and easy chip clearance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for universal compatibility with drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eCompact 3-inch overall length with 0.75-inch flute length for rigid performance in shallow bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, milling machines, lathes, and CNC machining centers equipped with drill chucks or collet systems accepting a straight-cylindrical shank of this diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists in machine tool spindles — ensure the machine is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the chuck or collet and confirm runout is within acceptable limits before cutting. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use a reamer to remove excessive stock; pre-drill or bore the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0845 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: HSS\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\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: 72008451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727244362034,"sku":"72008451","price":39.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_c4b91690-ad6c-47d6-8762-4af39bcde412.jpg?v=1788675294","url":"https:\/\/voomisupply.com\/products\/hertel-72008451-chucking-reamer-0-0845-in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
