Hertel 2341451 Bridge Reamer 1/2 in Hss 5 Flute

Product Description

The HERTEL 2341451 is a bridge reamer designed for enlarging and aligning holes in structural steel, fabrication work, and heavy-duty machining applications. 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.

This 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.

Key Features

• 1/2-inch cutting diameter with matching 1/2-inch quick-change hex shank
• High-speed steel construction for durability in ferrous materials
• Oxide finish for basic corrosion and heat resistance
• 5-flute left-hand spiral geometry promotes smooth chip flow and reduced chatter
• Right-hand cutting direction compatible with standard drill motor rotation
• 4-inch flute length and 5-7/8-inch overall length suit typical structural hole alignment depth requirements

Compatibility

Designed 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. Confirm shank compatibility with your specific tool chuck or quick-change adapter before use.

Installation Notes

Bridge reamers are installed and operated by qualified machinists, ironworkers, or fabricators familiar with rotating cutting tools. 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.
