Built from high-speed steel (HSS) with an oxide finish, this reamer features a 1\/2-inch cutting diameter, a 5-flute left-hand spiral configuration, and right-hand cutting direction. The spiral flute geometry provides smooth chip evacuation and consistent surface finish through the cut. With a flute length of 4 inches and an overall length of 5-7\/8 inches, it handles typical structural alignment tasks without excessive overhang. The quick-change hex shank allows fast tool changes in compatible drill motors and magnetic drills used in ironwork and steel erection.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for use by ironworkers, structural fabricators, and machinists working on steel connections where bolt holes require alignment or enlargement to final specification. It is commonly used with portable magnetic drills, handheld drill motors, and drill presses on job sites and in fabrication shops. The 5-flute design supports moderate feed rates in ferrous materials, making it a practical choice for production and field alignment work on structural members.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch cutting diameter with matching 1\/2-inch quick-change hex shank\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish for basic corrosion and heat resistance\u003c\/li\u003e\n  \u003cli\u003e5-flute left-hand spiral geometry promotes smooth chip flow and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard drill motor rotation\u003c\/li\u003e\n  \u003cli\u003e4-inch flute length and 5-7\/8-inch overall length suit typical structural hole alignment depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard bridge reamer for use with quick-change hex shank drill motors and magnetic drills commonly used in structural steel fabrication and ironwork.

Secure the workpiece before operation and ensure the shank is fully seated in the chuck or quick-change adapter. Always use appropriate cutting fluid for the material being reamed to extend tool life and maintain finish quality. Wear appropriate PPE including eye protection when operating reaming equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Type\u003c\/strong\u003e: Bridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Quick-Change Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 2341451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732401586482,"sku":"2341451","price":107.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f76559d79e83b4dfea8be9ff9a64a93_5020272d-0e88-4c1c-bf6c-9fa454d4853a.jpg?v=1788742439","url":"https:\/\/voomisupply.com\/products\/hertel-2341451-bridge-reamer-1-2-in-hss-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
