Step 1
Check out the chuck size of the drill. There are three typical sizes of chucks: 1/4 inch, 3/8 inch and 1/2 inch. Typically a 3/8 inch chuck should be a good choice for home use. Chucks that are 1/4 inch are limiting in the bits that you can use and 1/2 inch chucks are suited for larger, heavy-duty jobs.

Step 2
Decide between a corded or cordless model. It is easy to find both models so it comes down to personal preference. Cordless drills offer the convenience of being portable but they can be bulky. Corded drills may be slimmer and they don't need to be charged but they can be limiting because of the power cord.

Step 3
Find out how much power you need in your drill. Corded drills measure power in amps and cordless drills measure power in volts. The more amps or volts mean the drill can produce more power for bigger, tougher jobs. A higher power can mean a heavier and more expensive drill so you need to find a balance between power and cost.

Step 4
Pick a drill with variable speeds and a reverse feature. You can find these features standard on most drills and they will make many of your jobs easier.
-
Step 5
Look for extra features to suit the needs of your jobs. You can find angle drills that can fit into hard to reach places such as around corners or in between studs. There are also hammering drills that use a hammering action that will let them drill through materials like masonry and concrete.

Step 6
Hold the drill in your hand and make sure it is comfortable to you. If you will use the drill often, you want to make sure it is easy to hold, to avoid sore hands or even blisters from frequent use.
