Built from high-speed steel with a right-hand spiral flute configuration, it delivers consistent bore accuracy and smooth surface finishes in production and job-shop environments. The straight-cylindrical shank allows direct mounting in standard chucks and collets on drill presses, lathes, and CNC machining centers. With an overall length of 4.125 inches and a flute length of 1.5 inches, it is suited for moderate-depth holes in ferrous and non-ferrous materials. Machinists and tool-and-die professionals are the primary users of this type of reamer.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for finish-reaming drilled or bored holes to a precise Letter F diameter of 0.2570 inches. It fits standard production workflows where tight hole tolerances are required, such as pin fits, bushing bores, and dowel holes in machined components. The 6-flute geometry provides more cutting edges than a basic 4-flute design, reducing chatter and improving finish quality at moderate feed rates. Suitable for use in both manual and CNC machine tool setups across light manufacturing and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter F diameter (0.2570 inches) for precise finish reaming to tight tolerances\u003c\/li\u003e\n\u003cli\u003e6-flute right-hand spiral design reduces chatter and improves bore surface finish\u003c\/li\u003e\n\u003cli\u003eHSS construction provides adequate hardness and toughness for general-purpose metalworking\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 4.125 inches suits typical production hole depths\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with minimum order quantity of 1 unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit chucking reamer for any drill press, lathe tailstock, or CNC machining center equipped with a chuck or collet accepting a straight-cylindrical shank in the Letter F diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers of this type are installed by machinists or toolroom technicians into a rotating spindle chuck or collet. Ensure the machine spindle is fully stopped and locked out before changing tooling. The workpiece hole should be pre-drilled or bored to within approximately 0.005 to 0.015 inches of finished size before reaming; do not attempt to remove excess stock with a reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: Letter F (0.2570 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.2500 to 0.2999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches (101.60 mm)\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral 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\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: 72297062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728692543794,"sku":"72297062","price":55.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/511ef1c3f2b38f9af4c1de8fe37f18dc_900bf279-6511-4289-b69a-6fbdcadc5c4f.jpg?v=1788695119","url":"https:\/\/voomisupply.com\/products\/hertel-72297062-chucking-reamer-letter-f-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
