Apply pressure as you begin to drill. Squeeze the trigger of the drill slowly at first. Gain speed as you apply more downward pressure. Allow the tip of the drill bit to penetrate the surface of the rock. Apply more pressure, increase the speed of the drill, keep the bit perfectly straight and drill into the rock until the desired depth is reached.
