What is drill bit?

Drill bit is the part of a drill that helps to make holes in different materials like- wood, wall, metal, and many more.

There are different types of drill bits available in our market. But they mainly can be divided into three types: 1. Masonry drill bit 2. Metal drilling bit and 3. Wood drilling bit

We have divided it into three parts because, drill bits for masonry work, making holes in wood and metal are different.

Attach a drill bit in a Keyed chuck:

• Keyed chuck contains lots of holes in it. First you need to unlock all of them one by one with the chuck key. To unlock all the holes, you need to rotate the chuck key anti-clockwise.
•  After unlocking the chuck properly, now put the bit inside and at the center of the chuck.
• Then again lock all the holes with the help of the chuck key by rotating it clockwise.

Now, your drill is ready to work.

How to withdraw a drill bit from a drill

Like the previous one, drill bit can be removed in the three ways. And again, I’m going to discuss about one method (how to withdraw a drill bit manually).  You can also remove the drill bit with the drill itself and with the help of a key.

Withdraw a drill bit manually

• You can remove your drill bit manually if you have a modern drill. So, first of all identify the chuck of the drill and unlock the chuck by rotating it anti-clockwise.
• Firmly hold the handle of the drill with one hand and the chuck with another. And also make sure that you are rotating the chuck not the handle.

Sometimes the chuck gets stuck. So, to unscrew the chuck you need any of the three tools: Phillip’s head screwdriver, wrench or vice grips.

To unstuck the stuck chuck with wrench or vice grips, you need to rotate the chuck anti-clockwise holding it with a wrench or vice grips.

And to unstuck the stuck chuck with Phillip’s head screwdriver, you need to insert the screwdriver on the top of the chuck and rotate the screwdriver anti-clockwise.

Thus, the process of unscrewing a stuck chuck is almost similar.

Caution: Always buy a drill bit which is compatible with your drill.
