Many people have an electric drill at home. An electric drill is equipped with different drill bits. Due to different needs, we need to change different drill bits for use. So how do we replace drills?
For a Stanley hand drill, its chuck is tightened with a wrench. We turn off power to hand drill and steadily put drill up. Insert key into drill card and gear on key will align with gear on drill card. Turn wrench clockwise to tighten and counterclockwise to loosen.
To replace drill, you must put on gloves, pinch gourd neck of rubber drill and turn counterclockwise to complete disassembly of drill. Then turn it clockwise to replace drill with a new one. After replacement, connect power cord to turn on power, and check whether drill is firmly installed after being idle for 2 seconds.
