3/4 in Bridge Reamer for Metal, M2 HSS, 5-Flute, 1/2 in 3-Flat Shank

Key features

• [3/4 Inch Bridge Reamer] Designed to align, enlarge and smooth existing holes up to 3/4 inch, allowing bolts, rivets and other fasteners to fit more accurately. Ideal for bridge construction, steel erection, metal fabrication, equipment assembly and automotive repair.
• [M2 HSS Construction] Made from M2 high-speed steel for high hardness, wear resistance and dependable cutting performance. Precision-ground cutting edges help gradually remove material and create cleaner, more consistent holes when used with the proper speed and cutting oil.
• [Smooth, Controlled Reaming] Five right-hand spiral flutes help guide the reamer into slightly misaligned holes, remove material progressively and discharge chips during operation. The tapered point provides easier entry into predrilled holes and helps reduce sudden tool binding.
• [Non-Slip Chucking Design] The 1/2-inch shank features three flat gripping surfaces for a more secure hold in a compatible drill chuck. The integrated stop collar helps prevent excessive penetration after the required 3/4-inch hole size is reached.
• [Low-Speed Operation Required] This tool is intended for enlarging predrilled holes, not drilling directly through solid material. Use at low speed with cutting oil, keep the tool straight and centered, and apply steady forward pressure. Do not use impact mode, move the tool sideways or force it through the workpiece.

Align and enlarge predrilled holes accurately with this 3/4-inch bridge construction reamer. Designed for installing bolts, rivets and other fasteners, it helps correct slightly misaligned holes in structural steel, metal fabrication, equipment assembly and automotive repair applications. The reamer is manufactured from M2 high-speed steel for dependable hardness, wear resistance and cutting performance. Five right-hand spiral flutes gradually remove material while helping discharge chips, and the tapered point allows smoother entry into an existing hole. A 1/2-inch three-flat shank provides a secure grip in a compatible drill chuck and helps reduce slipping during operation. The built-in stop collar limits excessive penetration when the finished hole approaches 3/4 inch. Suitable for reaming compatible materials such as steel, alloy steel, aluminum, brass, copper, iron and certain plastics. Material hardness and cutting performance may vary, so test on scrap material when necessary. For best results, begin with a predrilled hole close to the required size. Operate at low speed, apply cutting oil and maintain steady axial pressure. Keep the tool straight and centered throughout the
