A Guide on Choosing an 18V Cordless Drill for Your Home

So now that you have finally decided to get yourself a new 18v cordless drill, you might have some difficulty picking out the right one from all the choices the market today. With the specifications, battery systems, the hype that each drill offers; it would probably fit to say that the quest to find the perfect one for you is a challenge.

Battery Types

There are essentially three types of batteries that are used to power a cordless drill. These are Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (Li-Ion). It would be a big help to have some knowledge on each of their pros and cons.

NiCd batteries are the first kinds of batteries that many people have been using until now. They are rechargeable and inexpensive. While anyone would highly benefit from its 1000 charging cycles, there are some things that owners should carefully look after. For one, it should never be completely drained. It should also be cooled first after charging before use. Also, Cadmium is dangerous to the environment.

A little less sensitive to charge/discharge patterns, NiMH batteries hit the market when there were restrictions on the use of Cadmium batteries. One problem with them, however, is that they have short battery lives. They are good for less than 1000 charges.

Li-Ion batteries were originally used for portable electronics and have just made its way for power tools. This might be the most expensive but if offers little disadvantages to its use. They have higher power density as well as less sensitivity to charge cycles and temperature.

Speed Settings

Variable speed triggers is another thing that you might want to look into. Aside from speed settings, newer drill models now have more than one-speed range. Mostly, it has a low-speed range used for typical screw driving along with a high-speed range for drilling. There are even high-end drills with a third-speed range setting.

Chuck Type and Size

The various sizes of drills give it the ability to perform a wide array of drilling jobs. Most 3/8-inch drills are good for household jobs. For most shops, however, a ½-inch will serve well. The new cordless drills in the market today already offer a keyless chuck. This means that losing its key should not be a problem. There are even more powerful and expensive cordless drills that have metal or plastic keyless chucks.

Clutch Settings

A drill has a clutch to allow you to control the torque of the drill. This should come important when doing a variety of jobs with it. If you intend to use it for many jobs, consider getting one that has the most settings than the others. Using the drill in a torque-sensitive environment may be a concern.

Spindle Lock

The spindle lock allows you to lock the drill’s spindle in place. This will make changing drill bits a little easier. This feature, however, is only common on those bigger drills. If you are able to find an 18v cordless drill with a spindle lock, it may be worth the minor splurge.
