Sized to wire gauge No. 20, it cuts to a nominal diameter of 0.1610 inches, placing it in the 0.1500 to 0.1999 inch decimal range. The reamer is ground from high-speed steel (HSS) with a bright, uncoated finish, providing adequate wear resistance for general-purpose reaming operations. Overall length is 4.5 inches with a 1.125-inch straight flute length, and the straight-cylindrical shank mounts directly in drill chucks, collets, or floating holders. Right-hand cutting direction is standard. Machinists and toolroom technicians install this reamer in drill presses, lathes, and CNC machining centers to bring drilled or bored holes to final dimensional tolerance.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer suits production and toolroom environments where holes must be brought to a consistent finish diameter at the No. 20 wire gauge size. Typical applications include jig and fixture work, dowel pin fitting, and through-hole finishing in steel, cast iron, aluminum, and brass. The straight flute geometry works well in short-chipping materials and allows easy chip evacuation in through-hole operations. It is sold as a single-piece unit with a minimum order quantity of one, making it suitable for both low-volume toolroom use and repetitive production reaming.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 20 diameter — 0.1610 inches nominal for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across common shop materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — ready for use or compatible with field coating if required\u003c\/li\u003e\n  \u003cli\u003eStraight flute geometry promotes clean chip evacuation in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank accepts standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction — matches conventional spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with drill chucks or collet holders sized to accept a straight-cylindrical shank in the 0.1500 to 0.1999 inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed by machinists and toolroom technicians following standard machine shop practice. Secure the shank fully in a drill chuck, collet, or floating reamer holder before powering the spindle; never run a reamer in a loose or improperly tightened holder. Always remove the workpiece from service and de-energize the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: No. 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1500 to 0.1999 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\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 (High-Speed Steel)\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: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 144429600020000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699047498034,"sku":"144429600020000","price":49.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09cbafd9adf45262b0c4f73a39c05ff2.jpg?v=1788371640","url":"https:\/\/voomisupply.com\/products\/value-collection-144429600020000-chucking-reamer-size-20","provider":"Voomi Supply","version":"1.0","type":"link"}
