Constructed from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in a wide range of metals and plastics. The straight-cylindrical shank mounts directly in a drill chuck, collet, or machine spindle. With a 4.0 inch overall length and a 1 inch straight flute, this reamer is suited for manual drill presses, lathes, and CNC operations where tight hole tolerances are required. Right-hand cutting direction is standard for conventional clockwise spindle rotation.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for precision hole-finishing operations in machine shops, toolrooms, and production environments. It is appropriate for reaming through-holes and blind holes in steel, aluminum, brass, and similar workpiece materials where a close-tolerance bore is needed. The wire-size 27 designation places it in the 0.1000 to 0.1499 inch diameter range, making it a common choice for instrument, aerospace, and general mechanical assembly work requiring fine hole sizing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 27 diameter: 0.1440 inch for precise hole finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a broad range of materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry for clean, consistent stock removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for any drill press, lathe turret, or CNC machine spindle accepting a straight-cylindrical shank reamer in the wire-size 27 diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists and toolroom technicians. Secure the shank firmly in a drill chuck or collet before operation and verify runout before cutting. Always power down the machine and bring the spindle to a complete stop before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the best surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1440 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: 4.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 2291276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730937053490,"sku":"2291276","price":48.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560aeb02ec3ebf33aa2712c4aa7d1f31_736d47eb-62d1-4a22-b375-87fc9d7489fa.jpg?v=1788725032","url":"https:\/\/voomisupply.com\/products\/hertel-2291276-chucking-reamer-wire-27-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
