How can I use a drill bit to enlarge a hole effectively?

To enlarge a hole effectively using a drill bit, start by selecting a drill bit that is slightly larger than the current hole size. Secure the material you are drilling into place and insert the drill bit into the existing hole. Apply steady pressure and slowly rotate the drill bit in a clockwise direction. Continue drilling until the desired hole size is achieved. Be sure to periodically remove the bit to clear any debris and prevent overheating.
