It features a straight-cylindrical shank for secure chuck holding and four straight flutes with a right-hand cutting direction. The bright, uncoated carbide construction delivers consistent sizing performance in precision hole-finishing operations. With an overall length of 3 inches and a 1-inch flute length, this reamer is sized for short-reach applications requiring tight dimensional control. Machinists and tool-and-die professionals use this reamer to bring drilled or bored holes to final dimension with repeatable accuracy. The diameter tolerance of 0.0000 to 0.0002 inches supports close-tolerance fitment work.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for use in CNC machining centers, manual lathes, and drill presses where a floating or rigid chuck setup is employed. It is appropriate for finishing holes in steel, aluminum, and similar machinable materials where final hole diameter and surface finish are critical. The short flute length makes it practical for through-hole and shallow blind-hole reaming in production and job-shop environments. No. 3 wire size designation makes it a common selection when matching drilled pilot holes to close-tolerance pin or dowel fits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eNo. 3 wire size, 0.2130 inch diameter with tolerance of 0.0000 to 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of base materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003e3 inch overall length with 1 inch flute length for short-reach precision work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill chucks and collet holders accepting a straight-cylindrical shank at No. 3 wire size diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists following established shop safety practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the shank firmly in a compatible chuck or collet to minimize runout, which directly affects hole tolerance and tool life. Use appropriate cutting fluid for the workpiece material to extend reamer life and improve surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: No. 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2130 inches\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 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: 1 inch\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: Solid Carbide\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: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 79890422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755115512114,"sku":"79890422","price":87.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16044d9d934b1091940b31eb033c7bf5.jpg?v=1788951291","url":"https:\/\/voomisupply.com\/products\/hertel-79890422-chucking-reamer-no-3-solid-carbide-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
