DeWalt manufactures drills in 1/4-, 1/2-, and 3/8-inch drives and speciality drills. Models have either a single grip trigger or a dual grip system with a front pistol grip for extra control while drilling. Each of the drills operates in the same manner though some controls may be in a different position.
Plug the battery-charger power cord into an electrical socket. Insert the battery into the charger. A red light will flash to show it is charging. When the light is steady red, pull the battery out of the charger by squeezing the sides. Squeeze the battery sides and push it into the bottom of the drill. Release the sides for the battery to lock in position.
Push the trigger direction button to the centre position to lock the drill. Grasp and hold the rear half of the drill chuck in position. Grasp the font of the drill chuck with the other hand and turn it counterclockwise to open the jaws. Insert a drill bit into the jaws, hold the rear of the chuck in position and turn the front of the chuck clockwise to tighten it around the drill bit.
Press the "Forward/Reverse" button on the right side of the drill to put it in a forward direction. Place the bit on the material for drilling. Squeeze the trigger with light pressure to start the drill tip in the material without it wobbling. Increase the drill speed by squeezing the trigger with additional force after the tip enters the wood or metal to increase the drill speed. Release the trigger and let the drill stop. Press the "Forward/Reverse" button on the left side of the drill to place it in reverse. Squeeze the trigger and pull the drill up out of the hole.
Some DeWalt drills have a dual range gearing. Push the gear selector forward on top of the drill to select a low-speed high-torque setting or back for a high-speed low-torque setting. Turn the torque setting to a higher number to drill through dense materials when more power is needed. If the drill has a trigger and a pistol grip in front, operate the speed on the trigger with one hand and support the drill by holding the front grip while drilling. Use wood bits for drilling holes in wood and metal bits for drilling holes in metal.
Release a drill trigger and let it stop before changing torque settings or the direction. This allows the clutch to stop in the motor so it does not place stress on the motor.
