A great deal of home owners make use of a cordless drill at some time or other. Battery technology has advanced a lot in recent years and there are not many jobs that a cordless drill can't do. It can be difficult to choose between all the different models that are currently available because they have similar features. Let's have a look at the features that all good cordless drills should have.
One of the most important component of a cordless drill is the battery. The performance of the battery goes a long way to determining how good a drill is. Batteries have become smaller while their power and lifetimes have increased. Even 18-volt batteries are small and lightweight. This is one of the major advances of recent years and you should always look for a drill that has the smallest and lightest battery possible. You will also want to make sure that the drill comes with a second battery. This means that you can use the spare while the other battery is being charged. If you look for a charging time of 30 to 40 minutes, you will can work all day interchanging batteries as required.
The optimal type of battery to choose is a Lithium-Ion battery. These charge quickly and keep your drill running for as long as possible before they run out of charge. These batteries are also longer lasting in comparison to other designs.
The second thing to look for is a good mixture of torque and power. The torque is a measure of the turning power of the drill and reflects its ability to drill holes and drive screws into tough materials. High power usually comes in tandem with high speed. Make sure you get a drill with at least two speed ranges. This is important so that you can match the drill speed to the job at hand. This will give much smoother operation and more accurate results. A further point on the list is the ergonomic design of the cordless drill. This relates to how easy it is to hold and operate. This is usually governed by the size and weight of the drill. A large and heavy drill can be very tiring and also difficult to maneuver in tight spaces. The best drills have good balance as well so that the weight is uniformly spread.
Some other functions that come in handy are a LED light and a belt clip. The light will help you when you need to work in tight and dark spaces. The belt clip will allow you to keep the drill close by without having to put it down. You will find lots of good brands and DeWalt cordless drills are at the moment receiving really good ratings.
