There is nothing you cannot do with a good set of drill bits. Power drills save a lot of time and effort, especially on big projects.
Contractors can use these drills along with various bits to bore holes, install wires and create larger holes in walls for pipes and other infrastructure. With the right drill bits, you can even drill through plastic, glass, composite, copper, aluminium and steel. Start out with a basic set of bits and add new ones to your kit as needed.
