Value Collection ST0640200 Bridge Reamer 2 in Hss

Product Description

The VALUE COLLECTION ST0640200 is a bridge reamer designed to enlarge and finish holes in structural steel, heavy fabrication, and ironwork applications. Built from high-speed steel with a bright, uncoated finish, this reamer features a straight flute design and right-hand cutting direction. It measures 2 inches in diameter, with a 7-3/8 inch flute length and 13 inches overall length. The small end diameter is 1-1/4 inches. The shank is a 4MT Morse taper, making it compatible with standard drill presses, lathes, and milling machines equipped with the appropriate spindle. Five flutes provide consistent chip clearance and smooth bore finishing.

Bridge reamers are a standard tool in structural steel erection and heavy fabrication shops. They are used to align bolt holes in beams, columns, and plates where holes may be slightly misaligned after initial drilling. The 4MT Morse taper shank allows this reamer to mount directly in compatible machine spindles or be driven with a drift key. This tool is suited for professional ironworkers, millwrights, and fabrication machinists working on commercial and industrial structural assemblies.

Key Features

• 2 inches cutting diameter for structural hole alignment and finishing
• High-speed steel construction for durability in ferrous and non-ferrous materials
• Straight flute geometry with 5 flutes for efficient chip evacuation
• Right-hand cutting direction for standard machine operation
• 4MT Morse taper shank for secure mounting in compatible spindles
• Bright, uncoated finish — no added coating to affect dimensional tolerances

Compatibility

Designed for use in drill presses, lathes, and milling machines fitted with a Number 4 Morse taper spindle. Suitable for structural steel, fabrication, and general metalworking reaming operations requiring a 2 inch finished bore diameter.

Installation Notes

Installation and use should be performed by qualified machinists or ironworkers familiar with rotary cutting tools and taper-shank tooling. Power down and lock out the machine before mounting or removing the reamer from the spindle. Ensure the Morse taper shank and spindle bore are clean and free of chips or burrs before seating to prevent runout. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
