With a reamer diameter of 0.1247 inches and an overall length (OAL) of 3.5 inches, this tool delivers accurate, repeatable results in through-hole and blind-hole finishing operations. The straight flute geometry and bright, uncoated finish make it well-suited for cutting ferrous and non-ferrous materials where chip evacuation and bore surface finish are priorities. This reamer is typically installed by machinists and tool-and-die professionals using drill presses, CNC machining centers, or manual lathes.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in production and job-shop environments where close-tolerance hole sizing is required. The straight-cylindrical shank accepts standard drill chucks and collet systems, making it easy to set up in common machine tool spindles. It is classified as a dowel pin reamer, making it appropriate for finishing holes that receive dowel pins requiring precise press or slip fits. The 0.1247-inch diameter falls within the 0.1000 to 0.1499 inch reamer diameter range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1247-inch diameter for tight-tolerance hole finishing\u003c\/li\u003e\n\u003cli\u003eHSS construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e4 straight flutes with bright, uncoated finish for clean cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eClassified as a dowel pin reamer for precision fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in drill presses, CNC machining centers, and lathes equipped with standard drill chucks or collet holders accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by qualified machinists. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout is within acceptable limits before beginning the reaming pass. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow applicable shop safety protocols and machine guarding requirements during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1247 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eDowel Pin Reamer\u003c\/strong\u003e: Yes\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: 2558138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727502672178,"sku":"2558138","price":46.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_98c77c9c-3715-4476-a058-4093e6254f8e.jpg?v=1788678619","url":"https:\/\/voomisupply.com\/products\/hertel-2558138-chucking-reamer-0-1247in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
