Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores in materials where tight tolerances are required. It carries a wire gauge diameter designation of No. 28, corresponding to a decimal diameter of 0.1405 inches, and features a straight-cylindrical shank for secure chuck retention. With a 4-flute straight configuration and right-hand cutting direction, it delivers consistent material removal on a broad range of machine tools.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in drill presses, lathes, CNC machining centers, and manual milling machines where final hole sizing demands close control. The 2-7\/8-inch overall length and 1-inch flute length make it well suited for shallow to moderate-depth finishing passes in small-diameter bores. It is appropriate for job shops, toolrooms, and production machining environments where wire-size reamers are used for pin fits, dowel holes, and precision clearance bores. The under-size specification of 0.1240 inches under size is noted in the product attributes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size No. 28 with a decimal diameter of 0.1405 inches for precise small-bore finishing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides durability across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e4-flute straight geometry with right-hand cutting direction for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank seats securely in standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eCompact 2-7\/8-inch overall length suits short-reach bore finishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling option for wire-size chucking reamer applications requiring a No. 28 diameter in straight-flute HSS configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed and operated by machinists and toolroom technicians on powered machine tools such as drill presses, lathes, and machining centers. Always power down and lock out the machine before mounting or changing tooling. Secure the straight-cylindrical shank firmly in a drill chuck or collet to minimize runout, and use appropriate cutting fluid for the workpiece material to maximize reamer life and bore finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: No. 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1000 to 0.1499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnder Size Designation\u003c\/strong\u003e: 0.1240 inches under size\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 72290281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744858931506,"sku":"72290281","price":46.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51c095728745ff1dc969ca3208c4fa6_a57888f5-0474-49b4-90d7-85cdcaef3b2a.jpg?v=1788861648","url":"https:\/\/voomisupply.com\/products\/hertel-72290281-chucking-reamer-wire-28-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
