Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features six straight flutes that produce clean, accurate holes in a right-hand cutting direction. It has a nominal diameter of 3\/16 inches (0.1875 decimal inch), an overall length of 3.5 inches, and a 1.125-inch flute length. The straight-cylindrical shank seats securely in a drill chuck or collet. Machinists and tool-and-die tradespeople use this reamer for finishing operations that require tight dimensional tolerances and smooth bore surfaces.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for use in drill presses, lathes, and CNC machining centers wherever a 3\/16-inch finished-bore diameter is required. It is appropriate for general-purpose reaming in ferrous and non-ferrous metals, plastics, and similar machinable materials. The HSS construction handles moderate cutting speeds well and withstands the heat generated in typical shop reaming operations. It is sold individually and is a practical choice for low-volume production runs, maintenance shops, and toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16-inch (0.1875 inch) nominal reamer diameter for precise bore finishing\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes for smooth cutting action and clean surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across common shop materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, standard for most machine reaming setups\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 any machine tool that accepts a straight-cylindrical shank, including drill presses, engine lathes, and machining centers requiring a 3\/16-inch finished bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed and operated by machinists in machine tools; ensure the spindle is fully stopped and the tool is secured before making adjustments. The reamer should be run at reduced speed compared to drilling, with adequate cutting fluid applied to extend tool life and improve bore finish. Never run a reamer in reverse, as this will dull the cutting edges. Inspect the shank for nicks before seating it in the chuck to ensure concentricity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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\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 (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\u003eWeight\u003c\/strong\u003e: 0.1 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: 72291123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751131283762,"sku":"72291123","price":44.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf88eaf9ebf4558d4989e16d069817f8_6c33dc43-2576-4b0a-9fb6-38bca7404fdb.jpg?v=1788921783","url":"https:\/\/voomisupply.com\/products\/hertel-72291123-chucking-reamer-3-16-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
