Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 0.2850 inches in diameter and delivers a right-hand cutting action through six straight flutes. The 6-inch overall length and 1.5-inch flute length make it well-suited for general-purpose reaming operations in a machine tool setup. It is installed and operated by machinists, toolmakers, and production shop technicians working on metal components that require tight dimensional tolerances.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in drill presses, lathes, CNC machining centers, and similar machine tools where the reamer is held in a chuck or collet. It is appropriate for finishing holes in ferrous and non-ferrous metals in both job-shop and production environments. The straight-cylindrical shank provides straightforward mounting in standard toolholding systems. The 0.2850-inch diameter falls within the 0.2500 to 0.2999-inch reamer diameter range, covering common close-tolerance hole sizes in that interval.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS construction provides good wear resistance and toughness for general-purpose metal reaming\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes deliver a smooth, consistent finish on the hole wall\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard machine spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with a wide range of cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank mounts directly in standard chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length accommodates moderate workpiece depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard machine tool spindles accepting a straight-cylindrical shank; compatible with drill presses, lathes, and machining centers equipped with appropriate chuck or collet toolholding.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified toolroom technician should install and operate this reamer. Always power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Secure the shank firmly to prevent runout, which will degrade hole finish and dimensional accuracy. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 72028509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729765597490,"sku":"72028509","price":63.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_fce4263d-f49b-4e90-b9c6-3eabd3d5c923.jpg?v=1788709097","url":"https:\/\/voomisupply.com\/products\/hertel-72028509-chucking-reamer-0-2850-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
