How to change a drill bit. Power drills are a great invention by humans. Drills can be used in home improvements, construction, and even in the office.
There are so many types of drills handheld, electric, cordless, and even pneumatic ones among other ways you can use them.
If you want to hold the drill bit steadily for better control during your drilling job, then a keyed chuck is for you.
But if you prefer to just change holes easily on your workpiece such as for example when you’re making an oil filter adapter then you should choose a keyless chuck instead like this one.
How to change a drill bit
To change a drill bit, remove the wrench from the chuck. With your thumb and forefinger grasp the chuck. Turn it counterclockwise which opens the jaws of the chuck.
Remove the drill bit from the spindle. Place a new drill bit onto the spindle, then tighten down with your wrench to close the jaws of workshop tools no ordinary man.
We will follow these steps to replace a drill bit if it has a chuck key:
Using the chuck key
To tighten or loosen a chuck of a drill equipped with a chuck key, we use the head of the key. The head of the key resembles that of a toothed wheel crown.
To use it, insert the tip of the key into one of the holes present on the backside, with the tips fitting in between those of the chuck.
Be aware that this specific tool should normally already be stored somewhere on an electric drill; however, oftentimes it will come ready to use with just chuck wrenching it onto the back.
Most cordless drills typically house their keys on this same type of structure as well due to convenience.
Open the jaws of the chuck
Take the wrench and secure it on the drill to hold it still. Using a circular method, turn the wrench so that the jaws open up. Stop once enough space is present for the drill bit to be inserted into.
Note that there are three or four securing pieces positioned around the works of the chuck which help keep things in place and when a piece is out of place any adjustments can be made.
You need to remove the bit
When the jaws are fully open, with your thumb and forefinger take the drill. Remember to retrieve the bit before it falls and gets damaged because when the jaws are wide enough the bit can easily fall if you tilt the front of the drill towards the ground.
Most bits used for drilling will have a tendency to overheat when working at high speed in carbon steel, so make sure that you check your bit after removing it from the drill.
If you notice that there is any type of damage such as fraying or change in coloring (metal overheating) and dulling on both sides of the bit, do not reuse it and put it in a waste bin instead to ensure safety measures while using a drill with any other person or customer near you.
Replace the drill bit
When the jaws are fully open, insert bit. You need the smooth part of the bit to go between the jaws of the chuck. Hold it with your thumb and forefinger inside Search Source.
Hold it until jaws tighten on it, as it could be loose when tightening. Repeat this step if necessary to ensure a tight fit.
Tighten up the chuck
Hold the bit with one hand; with your other hand use a wrench to fix the bit in place by turning it clockwise.
Next, make sure that the nuts are fixed onto both ends of the bit and affirm they are fastened correctly (do this step to both ends).
Now give a final turn of the wrench in each of the pairs of slots provided for this purpose. In general, there are three spots where you can insert your key, which is denoted by pictures on your drill.
After completing this step you can now take off any parts related to locking or unlocking that are inserted into said slots. When your bit is secure you will want to stop holding it.
Now spin it around while pressing down on your drill’s trigger light so that you can test its functionality in drilling rock or ice (or whatever material is deemed best for your particular application).
