of wood 
workers and craftsman.

carve curves from straight stock, shapes edges, cut dove tales and much more.
A router is more of a finesse tool than one that relies on might. It uses high speed rotation of the bit rather then mass horse power to chew through a cut. As the speed of the bit is increased the router bit cuts a smoother profile.
The basic wood working router has a shaft coming from the bottom of the motor. It is fitted with a collet that holds a bit. The shank of the bit is securely held in place while the router shaft rotates up to 25,000 RPM's.
