One of the most versatile tools you can own is the power drill/driver. This is especially true if you get one with features such as variable speed and reverse. You want one with at least a 3/8 inch chuck. A 1/2 inch chuck will give you tremendous flexibility but is not generally needed for most home repair tasks.
If possible, get one with a key less chuck. You'll never have to worry about keeping track of a little tool to tighten the drill bit into the chuck, it can be easily done by hand.
How to Use a Drill/Driver
- Select the proper drill bit for the material you are drilling. Metal and wood usually can use the same type of drill bit, but masonry bits have a very special design.
- Put on eye protection. Hold the drill with both hands perpendicular to the hole you want to drill.
- With gentle pressure, push the drill into the material.
- If the drill is going into wood, you may need to pull the drill out periodically as the drill bit will probably clog. By pulling the drill bit partially out of the work while the bit is turning, it will self-clean.
- If the drill bit does clog (usually from pressing too hard and too fast), then pull the bit out and clean the clog out with a hard material such as a screwdriver or nail.
- Drilling through metal can be tricky. The bit may bind as it cuts through the other side. If this happens release trigger pressure immediately. Pull the bit back and slowly complete the cut. Here it is handy to have a reverse feature especially if the bit gets stuck when it binds.
- Once the drill penetrates the material you're done.
