Electrical Supply: Power Drills — What to Look for in a Power Drill
A power drill can help you seamlessly complete a project. Here is an overview of the types of power drills available, and the features they can offer.
Types of Power Drills
Pistol Grip: This the most common type of corded drill. It comes with a standard ‘pistol grip’ handle and many attachments, making it quite versatile. Bits and attachments are usually available that can turn it into an orbital sander, a small hand saw or a boring device.
Hammer Drill: Also called masonry drills, these are used for concrete or brick. The hammer mechanism rotates, and it’s ideal for heavier use on harder materials. Some only have a hammering function while others can either drill or hammer.
Drill Press: A drill press is to be used on a workbench. It is not portable and often used in workshops. It works by clamping the material that needs to be drilled down while a lever is used to pull the drill into the material. There are attachments that can turn it into a sander, polisher or honing machine.
Voltages of Electric Drills
Just as there are many different types of drills available, they also come in a variety of voltages. A high powered drill may come in handy for professionals while a homeowner, for example, likely would not require that type of power.
(Voltage is the amount of power that is available to the drill. It represents the amount of power the drill will have when it is being used. A higher voltage will provide more power.)
A 24-volt drill is more versatile and commonly offers a hammer drill setting that isn’t found in lower voltage drills. 18 to 24-volt drills are usually recommended for contractors and professionals.
Other Drill Features
When buying a drill, there are some other features that may affect your purchasing decision:
Brushless Motor: These can offer high efficiency for better run time, more power, greater durability and lesser maintenance. Drills that have this feature will also tend to be lighter and quieter.
Power Output: Look for this spec in the product details before you buy. It refers to the rating of the power capability of the drill. The units-watts-out (UWO) number measures the output, as a combination of speed and torque.
Built-in Light: Helps you see as you are using the drill.
Built-in Level: Helps you drill and install fasteners more accurately.
Adjustable Side Handle: Helps you perform heavy drilling with more stability and control.
Accessories: These can include cases, spare batteries and drill and driver bit sets.
The Comfort and Feel of a Power Drill
Another thing to thing about in terms of what to look for in a power drill: When choosing a power drill, you should also consider size and performance. Think about the work you need to do, the length of time you would likely be using the drill for, and consider the size, weight, and feel of the drill.
Two common drill handle styles are available. These include the ‘T handle’ drill which features a handle near the middle of the drill body. This can make for a better weight balance and less wrist strain. The other design is the ‘pistol grip’ where the handle is at the rear of the drill.
With a little advance knowledge of what you need and a little planning, finding the right tool for the job can be a whole lot easier. Don’t forget to check out what USESI has available in their online catalog, or give them a call to speak with their staff.
