Power Tools 101: Drills

Learn about Power Tools: Drills

With so many power tools on the market it can be difficult knowing which will be best for you and the jobs it will be required for – particularly if you’re a relative novice when it comes to power tools and don’t have any knowledge in this area. In today’s piece we will look at power drills and talk through all the main points that must be considered before purchasing a power drill. Although it may be easy to assume that a power drill is just a power drill (and will therefore do the job no matter it is) there are numerous things that must be taken into account before buying. So, if you’re on the look out for a power drill and aren’t sure where to start then this article is for you!

Corded or cordless? For most of those carrying out DIY tasks a cordless drill will more than suffice. Although they are less powerful than their corded counterparts, they make for up it by being lighter, very easy to use and a lot more versatile – you can use them in all manner of places, whereas a corded drill is limited to the length of its cord and any extension cable you may have. Having a cord may also increase the risk to safety, hence why a cordless drill is almost always the best option unless you’re carrying out extremely heavy work which requires a drill with more torque than a cordless drill can provide.

What type of battery type? If you do select a cordless drill then you’ll need to be aware of the various battery types available for cordless drills. The two main types are: Ni Cad and lithium-ion. The former tend to be heavier and much more bulky, but are cheaper, whereas the latter are lighter, smaller and hold their charge for much longer periods. All in all, if your budget stretches to it then we highly recommend an lithium-ion battery. If the jobs you’ll be carrying out with your drill are fairly large then it may be a good idea to purchase a secondary battery as a back-up just in case the primary battery loses its charge mid-job.

What power rating? Cordless drills come in a range of powers which are rated by voltage (7v to 24v). The higher the battery voltage the more power the drill will carry, which will makes drilling both easier and faster. On the flip side, the more powerful a battery the heavier it will be so this must be taken into consideration when selecting a model. In addition, just because the voltage is higher doesn’t mean than the battery will work for longer. If you’re using a corded drill then power is rated in wattage, and the greater the wattage the more power it has. One thing that must be noted is that the higher the power the more expensive a drill will typically be.

Is the drill right for you? Once you’ve considered all the above then you must see how the drill feels. Pick it up and have a good feel of it. Does it feel too heavy or is it just right? If it’s too heavy then you may struggle to use it for extended periods. Is the grip comfortable? A sift grip is ideal as this will allow you to use it for longer allowing you to complete your job(s) quicker and more efficiently.
