Import 20996 Bridge Construction Reamer 7/8 in Hss

Product Description

The IMPORT 20996 is a bridge construction reamer designed to finish and size drilled holes to precise tolerances in structural steel and heavy fabrication applications. Built from high speed steel, this reamer features a spiral flute design with five flutes, which helps clear chips efficiently and produces a smooth bore finish. The 7/8 inch diameter cutting end is driven by a 1/2 inch Morse taper shank, ensuring a secure, concentric fit in compatible taper-socket spindles. At 6 inches overall length, it provides adequate reach for typical structural hole-finishing work. This tool is suited for use in drill presses, magnetic drills, or bridge reamers used on job sites and in fabrication shops.

Bridge construction reamers are used in steel erection, structural fabrication, and heavy industrial settings where bolt holes must be aligned and brought to final diameter before fastener installation. This reamer is appropriate for use on structural steel members, gusset plates, and connection assemblies where tight hole tolerances are required. It is installed and operated by ironworkers, structural fabricators, and machining professionals working with ferrous metals and heavy plate stock.

Key Features

• 7/8 inch reamer diameter for precise hole finishing in structural applications
• High speed steel construction for durability in ferrous and hard material cutting
• Five-flute spiral design promotes efficient chip evacuation and smooth bore finish
• 1/2 inch Morse taper shank for secure, self-centering spindle engagement
• 6 inches overall length provides reach suitable for structural connection work

Compatibility

Designed as an OEM-style replacement or direct-use reamer for spindles and drill setups accepting a 1/2 inch Morse taper shank, commonly found in drill presses and magnetic base drills used in structural steel fabrication.

Installation Notes

This reamer is typically installed and operated by ironworkers or machining professionals using a drill press or magnetic drill with a compatible Morse taper socket. Ensure the machine is fully powered down and the spindle is locked before seating or removing the taper shank. Use appropriate cutting fluid when reaming ferrous materials to extend tool life and improve finish quality. Follow applicable shop safety procedures and any site-specific guidelines for structural fabrication work.
