Value Collection ST0720040 Bridge Reamer 5/8 in Hss 2MT

Product Description

The VALUE COLLECTION ST0720040 is a bridge reamer designed for enlarging and aligning holes in structural steel, fabrication, and heavy metalworking applications. Built from high-speed steel with a bright uncoated finish, this reamer features a 5/8 inch diameter cutting head, a 6-1/8 inch spiral flute length, and a 10 inch overall length. The 2MT Morse taper shank mounts directly into compatible drill presses, lathes, or magnetic drills. With a left-hand spiral and right-hand cutting geometry across five flutes, it produces a clean, true bore while efficiently evacuating chips away from the work surface.

This bridge reamer is suited for ironworkers, structural steel fabricators, and millwrights working on beam connections, gusset plates, and structural assembly where bolt holes require truing or enlarging to final size. The Morse taper shank makes it compatible with standard taper-socket tooling found in shop and field equipment alike. A small end diameter of 25/64 inch allows the tool to enter undersized punched or drilled holes and guide itself before full cutting engagement.

Key Features

• 5/8 inch cutting diameter with a 25/64 inch small end for self-starting entry into undersized holes
• High-speed steel construction for durability across structural steel and ferrous materials
• Left-hand spiral flutes with right-hand cut geometry for efficient chip evacuation
• Five flutes provide a smooth finish and stable cutting action
• 2MT Morse taper shank for secure, repeatable mounting in taper-socket tooling
• Bright uncoated finish — ready for use as supplied, compatible with cutting fluids

Compatibility

Designed as an OEM-style bridge reamer for use in drill presses, lathes, and portable magnetic drills equipped with a No. 2 Morse taper socket. Confirm taper socket size before mounting.

Installation Notes

Installation and use should be performed by a qualified machinist, ironworker, or fabricator familiar with rotating cutting tools. Secure the Morse taper shank fully into the spindle socket before operation and verify there is no runout before engaging the workpiece. Apply a suitable cutting fluid to extend tool life and improve bore finish when reaming ferrous materials. Always power down and lock out the machine before changing tooling or inspecting the reamer.
