Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate, controlled material removal to bring drilled or bored holes to a tight final diameter of 0.2495 inches. The straight-cylindrical shank allows secure chucking in standard drill chucks, collets, or machine tool holders. At 6 inches overall length with a 1.5-inch flute length, it is well suited for through-hole and blind-hole finishing at moderate depths. Right-hand cutting direction follows conventional reaming practice for CNC machining centers, lathes, and drill presses.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in machine shops, toolrooms, and production environments where close-tolerance hole finishing is required. It is appropriate for reaming ferrous and non-ferrous workpieces where a precision diameter in the 0.2000 to 0.2499 inch range is specified. The dowel pin reamer designation indicates suitability for finishing holes that accept standard dowel pins requiring a snug or press fit. Installation and use are performed by machinists and tool-and-die professionals working to engineering drawings that call out final hole size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2495 inch finished hole diameter for close-tolerance dowel pin and precision bore applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides good hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry suited for through-holes and materials that do not require the chip-breaking action of spiral flutes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect diameter accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for straightforward mounting in standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction consistent with conventional machine-tool spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill chucks, collets, and machine tool holders accepting a straight-cylindrical shank in the 0.2495 inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by qualified machinists following standard shop practices. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Pre-drill or bore the hole to within recommended reaming stock allowance before final reaming — do not attempt to remove excessive material in a single reaming pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2495 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\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 (High-Speed Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\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: 2558252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737179849010,"sku":"2558252","price":51.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_84199f1c-40d4-466e-a3bf-288d240bc836.jpg?v=1788785288","url":"https:\/\/voomisupply.com\/products\/hertel-2558252-chucking-reamer-0-2495-in-hss-straight-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
