Value Collection ST0740124 Bridge Reamer 1-3/8 in Hss

Product Description

The VALUE COLLECTION ST0740124 is a bridge reamer designed to enlarge and align existing holes in structural steel, heavy plate, and fabricated assemblies. Built from high-speed steel with a bright, uncoated finish, it features a 1-3/8 inch diameter cutting head and a 4MT Morse taper shank for secure seating in taper-socket spindles. The left-hand spiral, right-hand cut geometry produces a smooth finish while controlling chip flow away from the cutting edge. With five flutes and a 7-3/8 inch flute length, it handles deep through-holes with consistent stock removal. Ironworkers, structural fabricators, and millwrights are the primary users for this tool.

This reamer is suited for structural steel erection, heavy equipment fabrication, and bridge or frame assembly work where bolt holes must be brought into alignment before fastener installation. The 4MT shank mounts directly in magnetic drill presses, drill press quills, and heavy-duty portable rigs equipped with a matching Morse taper socket. The 1-1/8 inch small end diameter allows entry into undersized or misaligned holes before full-diameter engagement. It is intended for use on steel and similar ferrous materials where precise hole sizing and alignment are critical to structural integrity.

Key Features

• 1-3/8 inch cutting diameter with 1-1/8 inch small end for guided entry into misaligned holes
• High-speed steel construction provides durability and heat resistance during heavy-feed reaming
• Left-hand spiral, right-hand cut geometry controls chip evacuation and reduces chatter
• Five flutes deliver a consistent finish and even cutting load across the hole wall
• 4MT Morse taper shank seats securely in compatible drill press and portable drill spindles
• Bright, uncoated finish maintains dimensional accuracy without coating buildup

Compatibility

Designed for use in drill presses, magnetic base drills, and portable drilling equipment fitted with a No. 4 Morse taper socket. Suitable for structural steel fabrication and heavy plate alignment applications requiring a 1-3/8 inch finished hole diameter.

Installation Notes

Installation and operation should be performed by qualified ironworkers, machinists, or fabricators familiar with taper-shank tooling. Secure the Morse taper shank fully into the spindle socket and verify it is seated and locked before operation. Power down and de-energize the drill before mounting or removing the reamer. Use cutting oil or a suitable metalworking fluid to extend tool life and maintain surface finish quality.
