A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials (Figure 4-1). Drilling machines use a drilling tool that has cutting edges at its point.
Features and Benefits Drill press vises with an angle orientation feature a hand-tightening mechanism to lock the angle from 0 to 90 degrees. Stationary or fixed vises are used for machining straight surfaces. They can be fastened to the machine at either a parallel or at a right angle.
