Value Collection ST0740116 Bridge Reamer 1-1/4 in Hss 5 Flute

Product Description

The VALUE COLLECTION ST0740116 is a bridge reamer designed to enlarge and align holes in structural steel and heavy fabrication work. Built from high-speed steel with a bright, uncoated finish, it features a 1-1/4 inch cutting diameter, a 7-3/8 inch spiral flute length, and a 13 inch overall length. The 5-flute, left-hand spiral with right-hand cut geometry delivers smooth material removal and accurate hole sizing. A No. 4 Morse Taper shank provides secure, repeatable seating in compatible spindles. This reamer is suited for ironworkers, structural fabricators, and machinists working on bolted connection points in steel construction.

Bridge reamers see primary use in structural steel erection and heavy-duty fabrication shops where bolt holes must be brought to final diameter and brought into alignment across multiple plies of steel. The small end diameter of 63/64 inch allows entry into undersized or misaligned holes before the full cutting diameter is engaged. This tool is also used in maintenance and repair operations where worn or out-of-tolerance holes in heavy equipment frames, bridges, and similar structures require reconditioning to accept standard fasteners.

Key Features

• 1-1/4 inch cutting diameter for standard structural bolt-hole sizing
• High-speed steel construction provides durability in ferrous and non-ferrous materials
• Left-hand spiral, right-hand cut geometry reduces chatter and promotes chip evacuation
• No. 4 Morse Taper shank for positive, repeatable spindle engagement
• 63/64 inch small end diameter aids entry into misaligned or undersized holes
• Bright, uncoated finish suitable for use with cutting fluids

Compatibility

Designed for use with machine spindles and drill presses equipped with a No. 4 Morse Taper socket. Suitable as a direct-fit replacement for standard bridge reamers of the same diameter, flute length, and taper designation in structural steel and heavy fabrication applications.

Installation Notes

This tool is installed and operated by machinists, ironworkers, or toolroom personnel using a drill press, radial arm drill, or milling machine with a No. 4 Morse Taper spindle socket. Always secure the workpiece fully before engaging the reamer and apply an appropriate cutting fluid for the material being reamed. Inspect the Morse Taper shank and socket for burrs or contamination before seating to ensure full engagement. Operate at speeds and feeds appropriate for the workpiece material and tool diameter to avoid overloading the flutes.
