Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore quality in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With four right-hand cutting flutes and a 0.875 inch flute length, this reamer removes minimal stock while holding tight diameter tolerances. It is suited for machine-fed reaming operations on a drill press, lathe, or CNC machining center where hole finish and dimensional accuracy are the priority.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in light machining and precision hole-finishing applications across metalworking, toolroom, and maintenance environments. The 0.0990 inch diameter falls at the upper end of the 0.0500 to 0.0999 inch decimal-inch range, making it appropriate for small-bore work in instrument components, hydraulic manifolds, and precision fixtures. A licensed machinist or tool-and-die technician typically selects this tool when a drilled hole requires final sizing to close tolerance. The 3.5 inch overall length provides adequate reach for most bench-machine setups without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0990 inch finished bore diameter with four straight right-hand cutting flutes\u003c\/li\u003e\n  \u003cli\u003eHSS construction provides toughness and re-sharpenability for toolroom use\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e3.5 inch OAL with 0.875 inch flute length optimized for shallow to moderate bore depths\u003c\/li\u003e\n  \u003cli\u003eNot configured as an over\/under size or dowel pin reamer — standard nominal sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for machine-fed applications; compatible with any drill press, lathe tailstock, or CNC machine equipped with a chuck or collet holder that accepts a straight-cylindrical shank at this diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways power down and lock out the machine spindle before seating or removing the reamer from the chuck or collet. Secure the straight-cylindrical shank with adequate grip depth to prevent pullout under cutting load. Use an appropriate cutting fluid for the workpiece material to promote surface finish and extend tool life. Allow the reamer to reach full spindle speed before engaging the bore, and feed at a consistent rate to avoid chatter or oversize conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0990 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 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: 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: 0.15 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: 72009905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728124576050,"sku":"72009905","price":39.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_965a9568-e97b-4642-8bae-178d3f0df38a.jpg?v=1788688403","url":"https:\/\/voomisupply.com\/products\/hertel-72009905-chucking-reamer-0-0990-in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
