Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth bore surfaces in a wide range of drilling and boring applications. The reamer measures 0.2020 inches in diameter with a 5 inch overall length and a 1.25 inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collets. With 6 flutes and a right-hand cutting direction, it produces consistent, clean finishes suitable for close-tolerance work in production or maintenance environments.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in machine shop, manufacturing, and maintenance applications where a drilled hole must be brought to a precise final diameter. It is appropriate for use in drill presses, lathes, CNC machining centers, and manual milling machines. Typical applications include bearing seat preparation, bushing installation, and pin-fit work in ferrous and non-ferrous materials. The 0.2020 inch diameter falls within the 0.2000 to 0.2499 inch reamer diameter range, making it a go-to tool for fine-tolerance finishing in that size class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2020 inch cutting diameter for precise hole finishing\u003c\/li\u003e\n\u003cli\u003eHSS construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e6 straight flutes with right-hand cutting direction for smooth, consistent bore finish\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose reaming without added coating friction\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eCompact 5 inch overall length suits most machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers that accept straight-cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout before cutting. Always ream at reduced speed compared to drilling, and use an appropriate cutting fluid for the workpiece material. Never force the reamer through an undersized hole — ensure the pre-drilled hole is within the recommended allowance for the target diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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: 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\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: 72020209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749665177906,"sku":"72020209","price":54.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560aeb02ec3ebf33aa2712c4aa7d1f31_86370fec-6ed1-44d6-8233-03e416cfaf8f.jpg?v=1788908966","url":"https:\/\/voomisupply.com\/products\/hertel-72020209-chucking-reamer-0-2020-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
