Value Collection ST0640120 Bridge Reamer 1-5/16 in Hss

Product Description

The VALUE COLLECTION ST0640120 is a bridge reamer designed for enlarging and finishing holes in structural steel, fabrication work, and ironwork assembly. Built from high-speed steel with a bright, uncoated finish, it delivers consistent cutting performance across repeated use. The reamer features a 4MT Morse taper shank for secure mounting in compatible drilling machines and presses. With a 1-5/16 inch cutting diameter, 7-3/8 inch flute length, and 13 inch overall length, this tool is sized for heavy-duty structural reaming tasks. Straight flutes and a right-hand cut produce clean, accurate bores in ferrous and mild non-ferrous materials.

This bridge reamer is used in structural steel fabrication, ironworking, and construction applications where bolt holes require enlarging or alignment to precise tolerances. It is commonly applied in bridge construction, steel erection, and heavy equipment assembly. The 5-flute geometry distributes cutting load evenly and promotes smooth bore finish. Installation is typically performed by ironworkers, machinists, or fabricators operating drill presses, magnetic base drills, or heavy-duty handheld drilling equipment.

Key Features

• 1-5/16 inch cutting diameter with 1-1/64 inch small end diameter for tapered entry
• 7-3/8 inch flute length provides extended reach for thick structural members
• High-speed steel construction offers durability across repeated use in steel fabrication
• 4MT Morse taper shank ensures rigid, self-holding connection to machine spindle
• 5 straight flutes with right-hand cut for consistent, controlled material removal
• Bright uncoated finish suitable for use with standard cutting fluids and lubricants

Compatibility

Designed for use with drill presses, magnetic base drills, and machine spindles accepting a No. 4 Morse taper shank. Suitable for bridge and structural steel reaming applications requiring a 1-5/16 inch finished bore diameter.

Installation Notes

This tool is installed and operated by machinists, ironworkers, or qualified fabricators. Secure the Morse taper shank fully into the machine spindle before operation and verify positive seating to prevent slippage under load. Always apply a suitable cutting fluid or lubricant when reaming steel to extend tool life and improve bore finish. Power down and lock out the machine before changing reamers or clearing chips from the flutes.
