Electric drill: with or without cable?
The electric drill is ideal for works and long-term work and that demand power and resistance. The amperage should be between 3 and 7 amps. The engine has to have a power of between 800 and 2,500 laps/minute and that can be used on wood, metal, plastic, and concrete. To begin with, a 4 amp, 800 rpm drill will suffice.
Cordless drills are much more practical because they allow greater freedom of movement. Look at the voltage and pay attention to the speed of the motor: for “large projects”, choose one with a high voltage.
It is also important to check the battery’s autonomy, which is indicated by the abbreviation “Ah” (ampere-hour). However, the capacity of the battery will vary according to the intensity of the work performed.
Finally, it is worth knowing that for the same price, the electric drill has more power than a cordless one.
Do not choose an electric drill that’s too simple, even if you’re a debutant.
For example, it is better to choose a drill with which you can control the speed of rotation of the tool and have a percussion system, as it is very useful for drilling concrete or brick; in that case, the number of turns per minute should range between 2,800 and 29,600.
To control the depth of the holes, some drills are equipped with a metal rod that when you touch the wall, avoid further drilling. But this option is not essential: you can also buy small sleeves that adapt to all types of drills.
Look at how much the tool weighs. You will have to hold it for several minutes. It is convenient to know that a cordless electric drill weighs more than one cord.
Do not hesitate to pick them up at the store to check the weight. Is the size of the handle suitable for you? Is the angle of the tool convenient for you? Do you hold your weight well? It is better if you opt for a drill with rubber-wrapped grip, which provides more control.
What kind of work do you want to carry out? Choose the right bit according to the type of surface you want to drill: wood, stone, metal, tile, concrete …
The electric drill can also serve as an electric screwdriver, polisher or brush. It is not difficult to find accessories for polishing, brushing, milling, sawing, sharpening etc.
To use electric drill correctly
First, always fix the drill in the chuck with the drill unplugged! Put it in gear before putting yourself to make the hole to verify that the bit is well fixed.
Do not exert much pressure on the electric drill while you are using it. When you notice that the speed is reduced, pause to prevent the engine from overheating.
In terms of maintenance, as the materials used are plastic and steel, it is advisable to keep the electric drill in a slightly damp place. And do not forget to dust it off regularly!
