The first power tool that most people buy is a drill. It is possibly the most versatile professional tool and has completely revolutionized home repair, making most projects more convenient and possible for the average homeowner.
Power drills are used both as drills and as screw drivers, depending on the bit inserted in the chuck. They can be used to bore through wood, plastic, metal, and even concrete, if you use the correct bit for the job. This tool is hand held and features a reverse switch to change the rotation direction of the drill bit. They can be found as corded models or cordless but run by a battery. The battery powered drills are more convenient but are only as powerful as the battery is charged.
When using a battery-powered power tool, charge the battery as soon as you notice a decrease in performance and output. Most batteries will fully recharge in anywhere between one hour and 24 hours. Corded versions can always supply you with full power. When purchasing any tool, it is best review the features that differ in the various models before making your decision.
Handle Styles
Power drills come in three different handle styles: the T-handle, the pistol grip, and the right angle. The T-handle model has a handle near the center, which distributes the weight of the device for better balance and less wrist strain.
Most T-handle styles are cordless. Traditional pistol grip styles are also found as cordless models but also exist as corded types. The right angle version is most often used in places where space is restricted.
Power
Cordless drills are measured in volts are available in everything from 2 to 24 volts. The higher the voltage, the more powerful the device is, but also the heavier the power tool is. 12-14.4 volts will meet most the needs of most homeowners. The output of corded drills is measured by amps and the higher the amps, the more power it has. When deciding how much you need, consider the projects you will be using it for.
Speed
Look for a tool with a variable speed setting. Drilling through different materials require both different bits and different speeds. Harder materials need to be drilled at a lower speed and softer materials can be drilled at higher speed. As a homeowner, you will be doing a variety of projects and using a variety of different material and will want to use different speeds on the instrument.
Clutch
You will want a keyless clutch which will allow you to change bits without an additional tool. Also you will want an adjustable clutch setting. The clutch reacts to the resistance of the screw allowing you to bore holes of consistent depth. With an adjustable clutch it is less likely you will strip a screw or snap the head off all together.
Price
You can buy a power drill for as low as thirty dollars or spend as much as four hundred dollars. The price depends on the brand of the power tool as well as the quality and features provided. Often the price will be the deciding factor, but do your research and get the best tool offered within your budget.
