In this video, you'll learn how to use an electric drill, it's a electric tool used to precisely drill holes in different materials such as wood, plasterboard, concrete or earthenware
It's most commonly used function is the "drill" function, where the drill is simply spins, and the "impact drill" where the drill not only spins but also makes a hammering motion whilst drilling meaning it has an 'impact force' as well as a rotational force. This function is used to pierce hard materials such as stone or concrete.
The drill is equipped with an electronic rotational speed switch and 2 mechanical settings
It is also equipped with a depth gauge which allows to set the drilling depth to a specific measurement
The electric drill comes with an adjustable and removable handle which grants a stronger and more stable grip when drilling
At the end of the drill there is a drill chuck, in which is inserted the drill bit.
Some drill chucks, like this one, are auto-locking , you just have to screw the chuck to lock the drillbit in place
Place a drill bit (or drill hammer) adapted to the surface you're going to drill in the chuck
Be careful to correctly position the drill bit in the middle of the drill chuck
In general we differenciate 3 differents types of drill bits, the wood drill bit which has a pointed end and sharp edges.
The metal drill bit ends in a more cone-shaped point.
And the stone drill bit which has a nearly entirely rounded tip
drill bits are distinguishable by their diameter, which is often indicated on the bit itself
We'll start by drilling wood
Before using the drill, wear protectives gloves goggles and ear protection.
Insert the wood drill bit, mark the spot you wish to drill.
Adjust the drill rotation speed by turning the dial clockwise
Place the drill bit on the mark, make sure the electric drill is positioned vertically and start drilling.
To drill metal it is best to set the drill to its highest speed.
If you are drilling ceramics, lay transparent adhesive tape on the place you are going to drill to avoid any shards flying off, proceed slowly and do not push the drill down too bruskly
To drill concrete, use the impact drill function at a high rotating speed.
