7/16" Spiral Tapered Bridge Reamer Round 3-Flat Shank High Speed Drill Bit New

This bridge reamer is used to align existing holes before bolt or rivet installation. Its tapered point permits entry into overlapping holes. The 3-flat shank provides a positive grip in portable electric and pneumatic tools and prevents it from slipping in the drill chuck. Moreover, it is made of high-quality high-speed steel with processes such as quenching and fully grinding, making it strong and durable to use, as well as suitable for a wide range of applications.
Application
This product is commonly used in bridge, construction, steel erection, and automotive/truck trailer industries, especially in structural materials and non-ferrous metal materials such as steel, metal, alloy aluminum, brass, plastic, iron, nickel, copper, and cast iron.
