Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in small-bore applications where dimensional control is critical. The straight-cylindrical shank seats securely in standard drill chucks or collets. With four flutes and right-hand cutting direction, the tool produces a clean, consistent surface finish in a single pass. At 3 inches overall length and a 3\/4-inch flute length, it is well suited for shallow-to-moderate depth holes in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for use in machine shop, toolroom, and production environments where tight hole tolerances are required after drilling. Typical applications include reaming pilot holes, clearance holes, and pin-fit bores in small workpieces. It is run in CNC machining centers, knee mills, drill presses, and manual lathes with the part held stationary. Licensed machinists, tool-and-die makers, and precision fabricators are the primary users of this style of reamer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0855-inch finished bore diameter for tight-tolerance small-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides good wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating to add uncertainty to the finished hole diameter\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction for smooth, consistent stock removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without adapter\u003c\/li\u003e\n\u003cli\u003e3-inch overall length with 3\/4-inch flute length suits shallow and moderate-depth bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank of the appropriate diameter, including drill presses, milling machines, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists in the spindle of a machine tool — always power down and lock out the machine before changing tooling. Secure the shank fully in the chuck or collet to minimize runout, which directly affects finished hole quality. Use the appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not run a reamer in reverse, as this will damage the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0855 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: 0.75 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 72008550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752741077298,"sku":"72008550","price":39.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_097127d7-2699-4584-b5d9-c29a145d6b73.jpg?v=1788930048","url":"https:\/\/voomisupply.com\/products\/hertel-72008550-chucking-reamer-0-0855in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
