A finishing device for finishing the exterior, flutes and tip of a drill bit is disclosed. The finishing device includes a containment vessel which houses an abrasive media which may have a visco-elastic component and an abrasive component. The drill bit is inserted into or through the abrasive media and rotated. A rotary member may be connected to the shank of the drill bit to provide rotation of the drill bit. The drill bit displaces the abrasive media thereby finishing the exterior, flutes, cutting edges and tip of the drill bit.
