Value Collection ST0730100 Bridge Reamer 1 in Hss 5 Flute

Product Description

The VALUE COLLECTION ST0730100 is a bridge reamer designed to enlarge and align holes in structural steel and heavy fabrication work. Built from high-speed steel (HSS) with a bright, uncoated finish, it measures 1 inch in diameter with a 7-3/8 inch flute length and a 12 inch overall length. The 5-flute, left-hand spiral with right-hand cut geometry provides smooth chip evacuation and accurate material removal. The Morse Taper No. 3 shank seats directly into compatible machine spindles, making it a practical choice for ironworkers, structural fabricators, and millwrights working with drill presses or magnetic drills.

Bridge reamers are commonly used in structural steel erection, bridge construction, heavy equipment manufacturing, and other applications where bolt holes must be aligned across multiple plies of material. The tapered profile, starting at a 47/64 inch small-end diameter, allows the tool to be driven into misaligned holes and progressively bring them into true alignment before final reaming to the 1 inch finished diameter. This tool is suited for shop and field use wherever heavy-duty hole alignment and finishing are required.

Key Features

• 1 inch reamer diameter with a small end starting diameter of 47/64 inch for progressive hole alignment
• 7-3/8 inch flute length provides extended cutting engagement for thick material stacks
• Left-hand spiral, right-hand cut geometry promotes clean chip evacuation and reduces chatter
• 5-flute construction improves surface finish and distributes cutting load across the tool
• Morse Taper No. 3 (3MT) shank for direct mounting in compatible machine spindles
• High-speed steel construction with bright, uncoated finish suitable for general ferrous and non-ferrous materials

Compatibility

Designed for use in drill presses, magnetic base drills, and other machines equipped with a No. 3 Morse Taper spindle. Suitable for structural steel, bridge construction, and heavy fabrication hole-alignment applications.

Installation Notes

Installation and operation should be performed by qualified machinists, ironworkers, or fabricators familiar with rotating cutting tools. Ensure the machine spindle is powered down and fully stopped before inserting or removing the taper shank. Use proper cutting fluid for the material being reamed to extend tool life and improve finish quality. Secure all workpieces firmly before engaging the tool to prevent movement during the reaming operation.
