Different drills require a set of different kinds of drill bits, for both compatibility and purpose. Black&Decker power drills are commonly sold and used today with a keyless chuck. With this feature, you can change your drill bits to suit your current needs with ease.
The new chuck system also allows the automatic locking of the spindle once the drill is turned off. This new kind of power drill gives you the advantage of being able to tighten or loosen the chuck with one hand while the other holds the drill handle for stability. Have the new drill bit ready before starting the changing process.
- Check your equipment. Before changing the drill bit, make sure that the drill is not plugged. Remember that changing the drill bit on a plugged or working drill will prove to be disastrous in the event it powers up while you are changing the bit. If the drill you use has an "off" switch, then switch it off first. If it does not, then simply release the drill trigger. Drills without a power switch are normally provided with an automatic motor. It is expected to engage every time the trigger is pulled, and should automatically stop once it is released. If this is so, wait for the drill to come to a full stop. Then, unplug it or remove the battery pack.
- Take care when handling hot drills. After using your drill, the bit or the motor typically heats up. Changing the bit on a hot drill can be dangerous. To prevent injuries, wear gloves while changing the drill bits. You should also wear goggles to protect your eyes from any debris that the drill might be throwing around. You can also set your drill aside for a few minutes to cool down. A cooler drill is safer to work with, and can help lengthen the life of the drill.
- Hold the drill handle firmly. Locate the outer sleeve of the drill chuck. This is the part that connects the drill bit to the main body of the drill. Hold it using your other hand. This part should be rotated in a counterclockwise direction. This enables you to loosen the chuck. Rotate the sleeve until the chuck is loose enough for you to pull the drill bit off. Set this aside or directly put it inside your drill bit container to avoid losing it. Insert the new drill bit into the chuck. Check the position of the new bit. The cutting part should be facing upwards.
- Check if the drill is working normally. Hold the outer sleeve of the drill chuck again. Start rotating clockwise to slowly tighten the drill chuck. Plug in your drill or put the battery pack back in. Turn the drill on just to see if it would work properly before actually using it on your project. If it proves to work with problems or does not work entirely, unplug it again, and repeat the process with the same drill bit.
Always wear safety equipment when changing your drill bit. Read the manual and fully understand the parts and the measures needed to be followed. If there are things unclear to you, do not push through with the process. Consult your dealer first to ensure your safety.
