Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth surface finishes in production and maintenance applications. The reamer cuts on the right-hand rotation and features six flutes for stable, even material removal. It is sized to wire gauge No. 12, corresponding to a decimal diameter of 0.1890 inches, with an overall length of 4.5 inches and a 1.125-inch flute length. Machinists, tool-and-die makers, and maintenance technicians install this tool in drill presses, lathes, and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for light to moderate stock removal when finishing pre-drilled or bored holes to a close tolerance. The straight-cylindrical shank mounts directly in drill chucks, collets, or floating reamer holders, making it practical for both vertical and horizontal setups. It is appropriate for general-purpose applications in job shops, manufacturing facilities, and field maintenance environments where consistent hole diameter and finish quality are required in steel, aluminum, brass, and similar workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 12 wire size diameter: 0.1890 inches for precise hole finishing to close tolerances\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes provide even cutting load distribution and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction resists wear across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids on steel, aluminum, and brass\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard clockwise spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet system accepting a straight-cylindrical shank at this diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified technician should install and operate this tool following applicable shop safety procedures. Power down and lock out the machine spindle before mounting or removing the reamer. Secure the shank fully in the chuck or collet and verify runout before cutting. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain hole 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. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 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\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\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\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: 2291128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728501834034,"sku":"2291128","price":52.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560aeb02ec3ebf33aa2712c4aa7d1f31_1761605c-89d3-4170-a56b-18eb1660aeda.jpg?v=1788692257","url":"https:\/\/voomisupply.com\/products\/hertel-2291128-chucking-reamer-no-12-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
