CNC router bits are different from traditional bits in a few ways. First, the cutting edges on CNC router bits are typically much sharper. This allows them to cut more cleanly and quickly than traditional bits. Second, the design of CNC router bits is such that they can be used in a wide variety of materials, including metals, plastics, and wood. Finally, CNC router bits are often designed specifically for use with computer numerical control (CNC) routers. This means that they are often able to take advantage of the speed and precision afforded by these machines.
