A corded drill or also electric drill is the full term for what is commonly referred to as a ‘drill’, that is, a motor to which a drill bit is connected, whose function is to cut precise holes in materials. The drill bit is gripped by what is known as a chuck, and held in place by the user at the other end. Provided there is steady grip, a hole will be drilled into the material as intended. If the material requires further precision or strength, then a drill press should be considered as an alternative to the corded drill.

When you are in the market you need to make a choice from different kind of drills so to understand it better, here is a great guide to corded drills.

There are many types of corded drills available, and before you make your purchase you should be aware of the main kinds. Since old hand drills such as the bow drill and the brace and bit are not strictly corded drills at all, these are not included in the following summary.

Regular Corded Drill

These corded drills are what the majority of regular people needing to do some DIY are in search of. If you know where to shop, you can get these regular rotating corded drills at reasonable prices. Just beware of some sellers trying to sell you a high priced brand name that you might not require. Remember, the genus of corded drills can include some extremely powerful power tools, but you must always ask yourself the question, do I really need it for the job I have to do?

Hammer Drill

The hammer drill is the same as a normal corded drill, except that it has, as its name suggests, a hammer function in addition to the simple rotation of the drill. This high impact hammer, combined with (or separate from) the regular rotating drill, can make holes in the more hard, brittle materials such as stone, without fracturing the surroundings. If you need a hammer drill, also known as an impact drill, then you might want to consider hiring a professional in the first place. Careless use of these on brittle materials can often spell disaster.

Cordless Drill

 

Okay, now it’s obvious that a cordless drill does not fall under the category of corded drill, but you should know about the corded drill’s younger brother, since it is often a contender for your consideration in your home DIY efforts.

However, that is not to say that the cordless drill doesn’t have its industrial applications too: this type of drill can be surprisingly powerful, all powered by either a Lithium ion or Nickel Cadmium batteries. It has to be said that when searching for a cordless drill, Nickel Cadmium batteries are a thing of the past. They are inferior in every respect to the lighter, long lasting Lithium ion alternative.

Since, unlike corded drills, cordless drills operate on a battery pack, it is very useful to know a lot about their power source before going ahead with your purchase. Battery packs come in a variety of forms: 7.2V, 12V, 18V and 24V among the voltages available, and the increase in voltages over time means that modern cordless drills can often rival corded drills in terms of raw power, something which is quite an amazing feat considering their size.

Right Angle Drill

A right angle drill is a variety of corded drill which allows the user to access previously inaccessible places, by virtue of the drill chuck being at a right angle to the drill’s main body, instead of being parallel to it. Many DIY enthusiasts swear by the right angle drill as their ticket to more obscure places, but for the average job around the home such a drill might not be necessary.
