CNC Router Bits Demystified

Minneapolis maker Greg Flanagan demystifies CNC router bits on the 100kGarages blog.

CNC routers need bits. They determine the kind of carving you can do, the resolution of your finished designs, and how fast you can move through the material. They come with cutting edges that pull up or push down (sometimes both), they have square or shaped ends, they are made for speed or accuracy, and they come in diameters from a pinpoint to over an inch for standard CNC routing.
