The Independent Man's Friend - The Electric Drill

By Michelle Paige


Doing things yourself is what most of us often do nowadays. As such, a number of tools are being designed to help us complete these tasks ourselves. The most common tool any person who does things himself/herself, as was observed is the electric drill.

Electric drills are used for drilling holes for tasks like hanging photos on walls and also for fastening materials together necessary in jobs like building book shelves. With the creation of these electric drills, one can do those abovementioned tasks themselves. However, with the market offering various models of electric drills with functions that are sometimes nonessential but are added to enhance commercial appeal, consumers tend to find it difficult in choosing the best drill they must purchase. Fear not, this article lists various functions you must consider in choosing your very own electric drill.

Before looking onto their other functions, select first whether you will have a corded or a cordless electric drill. Then, you may look at the various bells and whistles on today's electric drills which include the following: power, speed, chuck size and type, hammer action, handles, depth stop, and screwdriver function.

Corded electric drills include dangling leads with attached plug that needs to be plugged on electrical supply. As such, there will be a limit on the distance you can work from the electronic socket. Nevertheless, the advantage of such corded drills is that they tend to be more powerful and have higher speeds than cordless electric drills. Cordless electric drills, on the other hand, are better options especially if you need to work around in an area where electrical supply is unavailable as cordless drills are portable and can be used until the battery pack is exhausted.

If you select corded electric drills, power is often quoted in wattage or horsepower. Keep in mind that in selecting the best electric drill, the more you intend to use a drill, the higher the input wattage or horsepower should be. This is the same for cordless models which are rated by voltage. The higher the voltage of the battery packs, the more powerful they are. Another feature you must look into is the speed of the electric drill. Remember that the ideal speed depends upon the size of cutting or driving tool attachment (drill/driver bit) and the material being drilled. Generally, corded drills offer higher maximum drilling speeds than cordless ones. For the chuck size w/c determines the size of shaft which can be driven by the drill, the larger the chuck size is, the more powerful motor is fitted. You must select keyless chucks to easily fit/remove attachments but you can use traditional chuck types if you prefer using keys to open/close attachments. The function that moves the drill chunk rapidly in and out, causing the drill bit to hammer its way into bricks and masonry on the other hand is the hammer action. Another feature you must look into before purchasing an electric drill is the handle. Always select one that is comfortable in your hands-i.e. the trigger and other controls are easy to operate. You may also select models with depth stop that prevents the drill bit from going too far or those models that have screwdriver functions.

If you still find difficulties in selecting the best model you may purchase, then you may select among electric drills manufactured by leading machine tool makers like Bosch. Bosch Bohrmaschine have various drills like the Hilti Bohrmaschine.
