Things to consider before buying a cordless drill

There are different types of drills in the market. Therefore, it is imperative to get one that will meet the needs of the work you want to carry out. Here are some of the things you should keep in mind when you are purchasing a cordless drill.

The power

One of the major aspects that you should consider is the power of a cordless drill. You can tell a drill’s power by looking at its voltage numbers. A higher voltage, however, indicates a heavier drill. I recommend choosing a drill whose power matches the needs of your DIY projects.

The chuck size

Majority of the cordless grills have a ½-inch or a 3/8-inch chuck size. The chunk size greatly determines the maximum size of the shank. Larger bits usually have wider shanks. The chuck size also plays a major role in the power of the drill. A bigger chuck size means a more powerful drill.

The comfort

A drill will help you carry out a number of tasks, some of which require you to work for extended durations of time. As a result, you need to have a drill that has a comfortable feel in your hands. You should purchase a device that delivers ease of operation.

The speed

Most cordless drills are fitted with low and high speeds. The lower speed is ideal for driving screws, while the high speed is ideal for drilling.

Another feature that makes the DCD790D2 an ideal drill is its brushless drill motor.

This makes the DCD790D2 very efficient, enabling you to carry out a number of tasks.
