Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this 4-flute reamer delivers clean, accurate bores in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank allows secure seating in standard drill chucks and collet holders. At 3 inches overall length with a 3\/4 inch flute length, it is sized for shallow through-holes and blind-hole finishing operations in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for machining applications that require tight hole tolerances at the small end of the decimal inch range, specifically within the 0.0500 to 0.0999 inch diameter band. Right-hand cutting direction makes it compatible with standard spindle rotation. Machinists, tool-and-die makers, and precision fabricators use this type of reamer in manual drill presses, CNC machining centers, and turret lathes when a drilled hole must be brought to final size with minimal stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 47 diameter: 0.0785 inch for precise hole finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across common work materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose reaming without added coating cost\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for consistent chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine spindles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application chucking reamer for standard drill chucks and collet systems accepting a straight-cylindrical shank in the small-diameter wire gauge range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers of this type are installed by machinists in drill presses, lathes, or machining centers. Secure the shank firmly in a properly sized collet or drill chuck before operation, and ensure the machine spindle is fully stopped before inserting or removing the tool. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Leave only the recommended amount of stock in the hole prior to reaming — typically 0.001 to 0.003 inch for tools in this diameter range is industry practice, but verify against your shop standard rather than relying on a single reference.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: 47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range (Decimal Inch)\u003c\/strong\u003e: 0.0500 to 0.0999 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\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: 2291474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747955540274,"sku":"2291474","price":35.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_74b85c21-8317-40b7-8cee-62b2a143c901.jpg?v=1788887440","url":"https:\/\/voomisupply.com\/products\/hertel-2291474-chucking-reamer-size-47-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
