CNCs are simply routers controlled by a computer. The electronics tell the router the exact tool path to take, how deep to cut, the speed of the spindle, etc. On the other hand, the bit determines the type of cut that can be made, the quality of the surface left over, the type of material that can be machined, how the chips are removed, and much more. Knowing the differences in CNC router bits will help you achieve the best results possible at your CNC.
How Router Bits Cut
Before we get started discussing CNC bits, it’s important to understand how router bits cut. Unlike a drill bit that has a cutting tip and flutes that draw the chips up and away from the cutting edge, router bits are designed to cut laterally. The tip will cut, like a drill, but the
