Value Collection ST0730044 Bridge Reamer 11/16 in 5 Flute 3MT

Product Description

The VALUE COLLECTION ST0730044 is a bridge reamer designed to align and finish holes in structural steel, heavy fabrication, and ironwork applications. Built from high-speed steel with a bright, uncoated finish, this reamer measures 11/16 inch (0.6875 inch) in diameter with a 7-1/8 inch flute length and an 11-3/4 inch overall length. It features a left-hand spiral with right-hand cut geometry, which helps push chips forward and reduce chatter during through-hole reaming. The 3 Morse Taper shank provides solid drive engagement in compatible drill presses and magnetic drills. Structural ironworkers, millwrights, and fabrication shops keep this tool on hand for aligning bolt holes in steel connections where holes may be slightly misaligned before fastener installation.

This bridge reamer is suited for use in structural steel erection, bridge construction, heavy equipment fabrication, and industrial maintenance. The tapered nose and spiral flute design allow it to walk into misaligned holes and gradually bring them into alignment without pre-drilling. It is intended for use in drill presses, magnetic base drills, or similar machine setups that accept a 3MT shank. The 5-flute configuration provides a smooth cutting action across a range of mild and medium-carbon steels. Operators working in field erection and shop fabrication environments will find this tool fits standard ironworker workflows.

Key Features

• 11/16 inch (0.6875 inch) cutting diameter for standard structural bolt-hole alignment
• 7-1/8 inch flute length provides reach for thick steel sections
• Left-hand spiral with right-hand cut geometry drives chips forward and reduces chatter
• 3 Morse Taper shank seats securely in compatible machine spindles
• 5-flute design delivers smooth finish and consistent stock removal
• High-speed steel construction withstands the heat generated in structural steel reaming

Compatibility

Designed as an OEM-style replacement or direct-use bridge reamer for drill presses and magnetic drills equipped with a No. 3 Morse Taper spindle socket.

Installation Notes

Bridge reamers are installed and used by ironworkers, millwrights, and machinists operating drill presses or magnetic base drills. Power down and lock out the machine before mounting or removing the taper shank from the spindle. Use a proper drift key to seat and eject the Morse Taper shank — do not use hammer blows directly on the tool body. Apply cutting fluid appropriate for steel when reaming to extend tool life and improve hole finish.
