With a reamer diameter of 0.3745 inches, this tool is spec'd as a dowel pin reamer, meaning it is ground to exact tolerances for close-fit hole finishing. The spiral flute geometry, right-hand cutting direction, and bright uncoated finish make it a standard choice for machinists and tool-and-die technicians who need consistent hole quality in ferrous and non-ferrous materials. It seats into any standard drill chuck or collet via its straight-cylindrical shank and is ready to run without additional tooling adapters.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for production and maintenance machining environments where precise bore sizing is required. It is commonly used in machine shops, toolrooms, and manufacturing cells for reaming pre-drilled holes to final diameter. The 0.3745-inch size corresponds directly to dowel pin fitment work, making it a practical selection for fixture building, jig plates, and precision assembly applications. The 1-3\/4 inch flute length accommodates typical material stack depths encountered in bench and CNC operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3745-inch diameter ground to dowel pin tolerance for close-fit bore finishing\u003c\/li\u003e\n\u003cli\u003e6-flute spiral configuration for smooth cutting action and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and right-hand spiral direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks, collets, and floating holders\u003c\/li\u003e\n\u003cli\u003eBright uncoated HSS construction suitable for a wide range of common workpiece materials\u003c\/li\u003e\n\u003cli\u003e5-inch overall length with 1-3\/4-inch flute length for versatile depth reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight-shank chucking reamer compatible with drill presses, manual mills, CNC machining centers, and lathes equipped with appropriate chuck or collet tooling that accepts a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by qualified machinists following proper machine lockout and spindle-stop procedures before tool changes. Ensure the shank is fully seated and secure in the chuck or collet before operation. Always ream from a pre-drilled undersized pilot hole and use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Do not use this reamer for rough material removal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.3745 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDowel Pin Size\u003c\/strong\u003e: 0.3745 D\/P\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: 72296577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734707142962,"sku":"72296577","price":78.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61b2d3eb40550056a09a0666151d5fae_a60f3198-6623-41e8-b4f3-c4e2286c4291.jpg?v=1788765485","url":"https:\/\/voomisupply.com\/products\/hertel-72296577-chucking-reamer-0-3745-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
