It features a straight-cylindrical shank for secure chuck mounting and a straight, 6-flute cutting geometry that produces clean, accurate bores in a right-hand cutting direction. The 1.25-inch flute length handles typical through-hole and shallow blind-hole finishing, while the overall length of 3.5 inches fits standard drill press, lathe, and milling machine setups. Machinists and tool-and-die professionals use this reamer for precision hole sizing in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for finishing holes that require tight dimensional control, particularly where dowel pin fit is critical. The 83246793 is designated as a dowel pin reamer for the 0.3745-inch dowel pin size, making it appropriate for fixture building, jig plates, and precision assembly work. It is used in machine shop environments on both ferrous and non-ferrous materials where solid carbide tooling is selected for its hardness and wear resistance compared to high-speed steel alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life and dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003e0.3745-inch finished diameter with a tolerance of 0.0000 to 0.0003 inches for precise dowel pin fitment\u003c\/li\u003e\n\u003cli\u003e6-flute straight geometry produces smooth bore finish with consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank mounts directly in standard drill chucks or collets without adapters\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — compatible with most cutting fluids and coolants\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, standard for conventional reaming operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for 0.3745-inch dowel pin hole finishing in standard drill press, lathe, or milling machine setups that accept a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists familiar with machine tool setup and cutting tool practices. Ensure the spindle and workpiece are properly secured before starting the cut, and power down the machine before changing or inspecting tooling. Use appropriate cutting fluid or coolant recommended for the workpiece material to maintain tool life and surface finish. Always follow applicable shop safety procedures when handling carbide tooling, as edges are brittle and sharp.\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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 Size\u003c\/strong\u003e: 0.3745 D\/P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 83246793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727098216754,"sku":"83246793","price":153.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99831a6ce0ef9efb43c2020f23a10f0d.jpg?v=1788673283","url":"https:\/\/voomisupply.com\/products\/hertel-83246793-chucking-reamer-0-3745-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
