Value Collection ST0730060 Bridge Reamer 15/16 in Hss

Product Description

The VALUE COLLECTION ST0730060 is a bridge reamer designed for enlarging and aligning holes in structural steel, heavy fabrication, and similar metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a 15/16 inch diameter, a 7-3/8 inch flute length, and a 12 inch overall length. The left-hand spiral, right-hand cut geometry helps pull chips away from the cutting edge during operation, reducing heat buildup and improving hole finish. A No. 3 Morse Taper (3MT) shank provides secure, concentric seating in compatible drill presses, lapping machines, and portable drilling equipment used by machinists and structural ironworkers.

This bridge reamer is suited for structural steel erection, bridge construction, and heavy industrial fabrication where bolt holes require final sizing or alignment before fastener installation. The five-flute spiral design delivers smooth stock removal in ferrous and non-ferrous metals. It is typically used in fixed or portable drilling setups where a Morse taper spindle is available. The 0.9375 inch decimal diameter makes it a standard choice when reaming holes to accept 15/16 inch fasteners.

Key Features

• 15/16 inch (0.9375 inch) reamer diameter for standard structural fastener hole sizing
• High-speed steel construction provides durability in ferrous and non-ferrous metals
• Left-hand spiral, right-hand cut geometry evacuates chips efficiently and reduces chatter
• No. 3 Morse Taper shank seats securely in compatible machine spindles
• Five-flute design delivers consistent surface finish and fast stock removal
• Bright/uncoated finish suitable for general-purpose reaming without coolant-specific coating requirements

Compatibility

Designed for use in drill presses, radial arm drills, and portable drilling equipment fitted with a No. 3 Morse Taper (3MT) spindle socket.

Installation Notes

Installation and operation should be performed by a qualified machinist or ironworker familiar with rotating cutting tools and machine tool safety. Secure the Morse taper shank fully into the spindle before operation and verify the taper is clean and free of debris to ensure concentric seating. Always power down and lock out the machine before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish.
