Built with a 0.2280-inch diameter (Wire Size No. 1), this reamer delivers accurate, repeatable sizing in drilled or bored holes. The 6-flute spiral configuration with right-hand spiral direction provides smooth cutting action and improved chip evacuation compared to straight-flute designs. With an overall length of 3-7\/8 inches and a 1-1\/2-inch flute length, this tool is suited for use in CNC machining centers, manual mills, and drill presses. Machinists and tool-and-die professionals install this reamer using a standard straight-cylindrical shank chuck setup.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for finishing holes in the 0.2000-to-0.2499-inch decimal inch diameter range, targeting the precise 0.2280-inch finished bore. It is well suited for production and maintenance machining environments where close-tolerance hole sizing is required. The HSS construction handles a wide range of ferrous and non-ferrous workpiece materials at moderate cutting speeds. Its compact flute length makes it appropriate for through-holes and shallow blind holes in general metalworking setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2280-inch (No. 1 wire size) diameter for precise hole finishing in the 0.2000-to-0.2499-inch range\u003c\/li\u003e\n\u003cli\u003e6-flute spiral geometry with right-hand spiral direction for smooth cutting and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eHSS construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003e3-7\/8-inch overall length with 1-1\/2-inch flute length for controlled reach in shallow to medium-depth holes\u003c\/li\u003e\n\u003cli\u003eNot configured as a dowel pin reamer or over\/under size reamer — intended for standard on-size finishing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill press, manual mill, and CNC machining center setups accepting straight-cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed by a machinist or toolroom professional using a standard drill chuck or collet that accepts a straight-cylindrical shank. Secure the shank fully in the chuck before operation and verify runout with a dial indicator when close tolerances are required. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always pre-drill or bore the hole to near-final diameter before reaming — never use a reamer to remove excessive stock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2280 inches (Wire Size No. 1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral 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\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: 72294010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733374173490,"sku":"72294010","price":55.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c26009126499e218bbcd7aa61ac64bab_ec75a987-056a-4e3d-a93e-0afa55b64a43.jpg?v=1788754861","url":"https:\/\/voomisupply.com\/products\/hertel-72294010-chucking-reamer-1-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
