Built from high-speed steel (HSS) with a bright, uncoated finish, it is sized to wire gauge number 51, corresponding to a decimal diameter of 0.0670 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With a 3-inch overall length and a 3\/4-inch flute length, this reamer is suited for light-duty through-hole and blind-hole finishing operations where tight diameter tolerances are required. Right-hand cutting direction is standard for conventional machine reaming applications.\u003c\/p\u003e\u003cp\u003eThis reamer is used in machining environments where small-diameter holes must be brought to a precise finished size. Typical applications include finish-reaming pilot holes, dowel pin holes, and clearance holes in ferrous and non-ferrous stock. It is appropriate for use in drill presses, CNC machining centers, turret lathes, and manual milling machines. The 4-flute geometry provides a stable cutting action at small diameters. Machinists, toolroom operators, and precision fabricators are the primary users of this tool size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 51 with decimal diameter of 0.0670 inches for precise small-bore finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003e4-flute straight geometry delivers stable cutting action and consistent hole quality\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional machine reaming setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in machine tools accepting straight-cylindrical shank tooling at this diameter range, including drill presses, lathes, and milling machines with appropriate chuck or collet capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists in properly equipped machine tool environments. Ensure the machine spindle is fully stopped and de-energized before mounting or removing the reamer. Secure the shank firmly in a drill chuck or precision collet to minimize runout, which directly affects finished hole quality. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: 51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0670 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: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 2291516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728719839538,"sku":"2291516","price":35.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_67abf20f-2fec-4667-8197-9f209c259525.jpg?v=1788695451","url":"https:\/\/voomisupply.com\/products\/hertel-2291516-chucking-reamer-size-51-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
