Value Collection ST0730108 Bridge Reamer 1-1/8 in Hss 5 Flute

Product Description

The VALUE COLLECTION ST0730108 is a bridge reamer designed for enlarging and aligning holes in structural steel, fabrication work, and heavy-duty metalworking applications. Built from high-speed steel with a bright, uncoated finish, this reamer features a 1-1/8 inch diameter, a 7-3/8 inch spiral flute length, and a 12 inch overall length. The left-hand spiral combined with right-hand cutting action helps pull chips away from the work surface during operation, reducing the risk of chip packing. A No. 3 Morse taper shank provides secure, positive drive in compatible drill press spindles and reamer holders. This tool is intended for use by machinists, ironworkers, and structural fabricators working with manual or machine-driven setups.

The ST0730108 bridge reamer is suited for structural steel erection and fabrication shops where bolt holes require alignment or enlargement prior to fastener installation. Its 5-flute spiral configuration promotes smooth, consistent material removal at larger diameters. The Morse taper shank makes it compatible with standard drill press and milling machine spindles equipped with a No. 3 MT socket. This reamer handles moderate to heavy stock removal in steel and similar ferrous materials in both shop and field fabrication scenarios.

Key Features

• 1-1/8 inch reamer diameter for enlarging or aligning structural bolt holes
• 7-3/8 inch flute length provides extended reach into deep hole applications
• Left-hand spiral with right-hand cut draws chips up and away from the cutting zone
• 5 flutes deliver smooth, consistent material removal and improved surface finish
• No. 3 Morse taper shank for secure seating in compatible spindles and holders
• High-speed steel construction offers durability across ferrous material applications

Compatibility

Designed to fit machine spindles and reamer holders accepting a No. 3 Morse taper (3MT) shank, as commonly found on drill presses, lathes, and milling machines used in structural and general metalworking applications.

Installation Notes

Bridge reamers are typically installed and operated by machinists or ironworkers using drill press, lathe, or handheld magnetic drill setups equipped with a matching Morse taper socket. Ensure the machine is fully powered off and the spindle is at rest before seating or removing the taper shank. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve hole finish. Secure workpieces firmly before reaming to prevent movement during cutting.
