Cordless drills are portable electric drills that use rechargeable batteries. They basically have the same features as the AC mains-powered drills minus the limitations of the cord. You can choose from a small and lightweight cordless driver for simple house repairs or a bigger cordless drill for extreme major construction. There are also different drills for drilling on wood, concrete or brick. Some newer models even have built-in LED lights for added convenience. Whatever your drilling needs may be, you are sure to find a cordless drill that will match your requirements.
Most of the modern cordless drills available in the market today come in two fundamental sizes: ½ inch and 3/8 inch. They normally have a minimum of 15 clutch settings for driving screws, forward and reverse functions and at least 2 speed ranges and electric brakes for added power and control. Some cordless drills also come with a supplementary handle for better balance and safer handling.
Cordless Drill Batteries
When choosing which cordless drill to buy, do not forget to examine its battery voltage and torque. The power of a cordless drill can be attributed to its battery voltage while torque measures the amount of twisting force of the drill or driver. The higher voltage, the higher the torque. The higher the torque, the greater drilling power and impact. The battery voltage of cordless drills range from as low as 6V to a maximum of 36V.
Torque is measured in inch-pounds. You just have to bear in mind that greater power means heavier weight. A heavy running power drill might only cause fatigue and tension to your arms and muscles. You have to remember that you have to feel comfortable using it, including all the nitty gritty controls.
You also have to consider the type of rechargeable batteries before buying a cordless drill. Although they are more expensive, Lithium-ion (Li-ion) batteries are highly recommended because they last longer. Nickel-cadmium (Ni-Cd) or nickel-metal hydride (NiMH) batteries are alternative budget choices but are not so environment-friendly. They also add up to the drill’s weight which is not very ideal. But, whichever battery you choose, you need to look for a complementing smart charger to prolong your battery’s useful life.
A good Cordless Drill will be invaluable to any small or large job around the house so choose wisely but make sure you have one.
Cordless Drill Battery Charger
There are many different manufacturers who sell a cordless drill battery charger of some kind, and though these usually come packaged with your cordless drill set, you may at some point need to purchase a different one, and in this case it is good to know what to look out for, since they come in many different shapes, sizes and prices.
First off, you need to know what type of battery your cordless drill uses because there are many different battery types, and just as many types of cordless drill battery charger. There are some chargers that can only charge specific battery types and others who can charge multiple types, but you need to be aware of this because if you make use of the wrong type of cordless drill battery charger for your battery you could end up destroying it or worse – you could injure yourself severely.
The cordless drill battery charger also comes in an array of different types with varying types of plugs or jacks and so forth, some to be used in your work area and some allowing you to charge them on the go, such as in a car or truck. You thus need to know which cordless drill battery charge is appropriate for what you are going to be doing with it – for example if you are a self-employed handyman, you would take your cordless drill battery charger along to various jobs and be driving a lot, so you would benefit from a portable charger that slots directly into the power outlet in your vehicle.
You could pay anything from twenty to around a hundred dollars for a cordless drill battery charger, and you need to know that you are getting your money’s worth when forking out the cash. You should remember that the smaller sized portable chargers would cost you less than the heavy duty universal chargers that can charge almost any type of cordless drill battery. A good idea is to take your battery with you when purchasing a charger so that you can verify with your vendor whether or not the charger is appropriate for you.
