A drill chuck is the part of the drill that holds the rotating bit in place. A drill chuck key is a small, ridged tool that fits into the grooves of the chuck to tighten and loosen the chuck. A chuckless drill is one that operates without these two features. In place of the chuck, there is a large plastic ring around the base of the rotating end of the drill, called a hand chuck. Typically, chuckless drills are not recommended for industrial construction use, but are very handy for smaller jobs.

Step 2
Firmly grip the base of the hand chuck with one hand.
Step 3
Squeeze the trigger of the drill until the screw (the part into which the drill bit is inserted) opens wide enough to accommodate the bit.
Step 4
Insert the bit. Keep the threads of the bit outside the screw.
Step 5
Place the drill in forward mode.
Step 6
Firmly grip the base of the hand chuck with one hand.
Step 7
Squeeze the trigger of the drill until the screw firmly grips the drill bit and will not tighten further.
Step 8
Continue to use the drill the same as you would a drill with a chuck.
Tip
If the bit becomes loose, grip the hand chuck and lightly squeeze the trigger.
Warning
Never operate power tools without being properly trained. Protective eyewear should always be used when operating a drill.
