Value Collection ST0630112 Bridge Reamer 1-3/16 in Hss

Product Description

The VALUE COLLECTION ST0630112 is a bridge reamer designed to enlarge and align drilled holes in structural steel, plate, and fabricated assemblies. It features a 1-3/16 inch cutting diameter, a straight 5-flute geometry, and a right-hand cutting direction. The shank is a No. 3 Morse Taper, allowing direct mounting in compatible drill presses, magnetic drills, or drill motors equipped with a Morse taper socket. Constructed from high-speed steel (HSS) with a bright, uncoated finish, it is suited for production and maintenance environments where hole alignment between structural members is required. The 7-3/8 inch flute length provides adequate engagement for thick stock and multi-layer assemblies.

Bridge reamers are used primarily by ironworkers, structural fabricators, and maintenance machinists to bring misaligned bolt holes into register on steel beams, gusset plates, and connection angles. The tapered leading point guides the tool into partially misaligned holes before the full-diameter flutes begin cutting. This tool is appropriate for both shop fabrication and field erection work where a No. 3 Morse Taper-equipped drill motor or drill press is available. The 12 inch overall length provides reach in confined structural connections.

Key Features

• 1-3/16 inch cutting diameter for standard structural bolt hole alignment
• 7-3/8 inch flute length for engagement in thick or stacked steel members
• No. 3 Morse Taper shank for secure, self-holding fit in compatible spindles
• 5-flute straight geometry for clean, efficient material removal in ferrous stock
• Right-hand cut with bright uncoated HSS construction
• Small end diameter of 59/64 inch for guided entry into misaligned holes

Compatibility

Designed for use with drill presses, magnetic base drills, and portable drill motors fitted with a No. 3 Morse Taper spindle or socket adapter.

Installation Notes

Bridge reamers are typically installed and operated by ironworkers or machinists. Ensure the Morse taper shank and spindle socket are clean and free of burrs before seating the tool. Secure workpieces firmly before reaming, and use appropriate cutting fluid for steel to extend tool life and improve finish. Always disconnect or lock out power to the drill before changing tooling per applicable safety standards.
