How to use drill chuck?--QINFENG HARDWARE

A drill is a must-have item for any home owner or construction professional. Drills are available in a variety of sizes and weights, and are run on a battery or an electrical cord. Older drills required the use of a special key, called a chuck, to change out the drill bit. Most newer models of drills are called keyless chuck drills and do not require this specialized key. Keyless chuck drills make jobs much faster and enable you to change out drill bits rapidly.

1.Hold the keyless chuck drill in your hand so that the end where the drill bit goes is facing upward.

2.Grasp the large plastic collar located around the end of the drill with one hand. The collar has thin tabs or ribbing on it to make it easier to grip.

3.Grasp the smaller extension at the end of the collar with your other hand. This is called the drill sleeve. Turn the sleeve counterclockwise until the center opening is large enough to insert a drill bit.

4. Insert a drill bit into the center of the opening with the sharp side of the bit facing outward.

5.Grasp the drill sleeve and turn it clockwise to secure the drill bit in place. When the sleeve will no longer turn, the bit is locked securely into the drill.

6.Use the drill as normal. When you are done, twist the sleeve counterclockwise to remove the drill bit and place it into the drill case for safe storage.
