 Use the power drill is not an easy task, especially if the surface is rough. The most common mistake made by nonprofessionals is not enough pressure while they are drilling something. As a consequence, drill starts to wander all over the surface before hitting its mark. So you can spoil a great deal of materials before you'll get the one you need. But fortunately due to the new idea of Bongkun Shin you can forget about this. It will help you solve your problem.
