The process is to loosen the chuck is just about rotating it in a counterclockwise direction.With a firm pressure of your fingers, unroll the chuck up until you can take the older bit out.

Step 2: Take the bit out
Once you’ve loosened the chuck, you might see the drill bit wobbling. Once it’s done, you can simply hold the bit with your fingers and take it out.In case the drill bit had been used just now, don’t dare to hold it with bare fingers as it would be so hot in temperature.
In those cases, use gloves or so to protect your finger. Is possible, hold it up while it’s cold enough to do so.
Step 3: Take the new bit and set
Now, select the right drill bit size to put into the drill. Once you have got the right one, place the smooth part of the bit into the jaw of the drill. The smooth part is in fact, there one that would go inside the chuck.
Once you’ve got the smooth part of the bit inserted into the jaws of the chuck, insert the bit into the chuck and pull it back towards you. The length of pulling it back would not be more than one centimeter.
Step 4: Press the trigger
To tighten the position of the bit into its place, you need to give the trigger a few shots. This can be done by squeezing the trigger for 1 to 3 seconds.While doing this step, use your other hand to hold the chuck. This will help the bit to stay in its place. Another benefit of holding the bit and chuck is, it will help the bit to be installed straight.
Step 5: See if there is any ratcheting mechanism
Some of the brands of drill machines come up with a ratcheting mechanism installed into the drills. In those cases, you have to work on the ratcheting mechanism to make the drill bit even stronger.To come up with this ratcheting mechanism, you need to firmly twist the ratcheting to the shank of the drill bit.
Once you have heard the click sound, you will get that it’s on its place.To engage the ratcheting mechanism finally, firmly twist it next to the chuck. This twisting should take place in a clockwise motion.
So, this was the most regular and easier method of how to change a drill bit by yourself. There is another minor method that involves using the chuck key. In case your drill driver comes with one, you can incorporate the chuck case to get it done.
