What to do if your drill bit gets stuck in chuck

Why does my drill bit get stuck

The chuck might not have been oiled. Oiling helps in the drill maintenance process (Qmillwright.com). It makes it easier to slide in and slide out the drill bit. If you oiled the machine enough, the chuck might have been overtightened. The vibrations might have pulled the chuck tighter on the drill bit. By the time you want to remove the bit, it is no longer possible since it is very tight.

Make sure you are using the right drill bit for the job since some bits are for drilling metal while others are for wood. That way, you reduce the chances that the drill bit will shear off or get stuck while drilling into the material.

How to fix a stuck drill bit

1. Start by identifying the type of chuck you have. Changing a drill bit will change, depending on your type of drill. Different drills will have chucks and ways to tighten the bits.
2. Set the drill to reverse. Use the tool power by running it, in reverse while holding on to the chuck. If the drill tool is not in reverse when trying to loosen the chuck, the drill may overpower your grip and keep spinning inside your hand. The rotation switch should be pressed in, from the left side on most drills. It might overpower you if you have it in reverse and the bit gets stuck. Set the drill at low speed and lightly tap the trigger to release power while applying resistance on the chuck. 
3. Increase your grip strength using a non-slip pad or a cloth. For increased grip, you can also use a wrench or vice.
4. Use a wooden mallet or rubber mallet if you have to decrease the damage on the bit or drill.
5. If you are struggling to remove the bit, spray a solvent like WD-40 inside the chuck to remove some of the corrosion, and it becomes easier to get out.
6. Lubricate the chuck with oil, to avoid getting a bit stuck. It will also prevent corrosion and rust.

1. Oil the areas where the parts move past each other, including behind the drillbit area.
2. Use alcohol or thinner to clean residual oil, grease, or sawdust off the outer chuck surfaces. That helps in gripping.
3. Use a tightening wrench, to grab around the fat chuck section, and a smaller channel lock to grab the slimmer chuck section.
4. Twist open.

1. Hold the bit close to the base with one.
2. Take the other and turn the chuck counterclockwise to release, or use WD40 on the chuck.
3. One channel lock plier holds the chuck and puts the drill in reverse.
4. The WD40 should allow the chuck to release easier.

Methods

Use a Dremel with ice.

Use a Dremel tool to carve out something using stacked blocks of ice. Start at the top and work your way down to get the outline of the project.

Use a screwdriver

1. Insert a screwdriver into the tip of the drill and turn the screw inside of the chuck counter0-clockwise to loosen it up enough to rotate the chuck. 
2. Once your chuck rotates again, replace the screw. 
3. Turn the chuck counterclockwise with a wrench if stuck.

Use a drill

1. Press the button on the left side of the drill, which dictates which direction the drill spins when you pull the trigger. 
2. Push the button on the left side to make the drill rotate counterclockwise.
3. Hold the chuck at the end of the drill to keep it from rotating while you pull the trigger on your drill.
4. Pull the trigger. 
5. Rotate the chuck with a wrench if it is stuck.

Use a screwdriver with ice.

Freeze it at an angle so that it works. Once you have your block of ice, use a screwdriver to carve out a chute or two.

Hold the drill steady and rock the drill.

Drill bits should stay straight on track once they get going. If you keep the drill motionless, you get a straight hole. A straight hole is a perpendicular,90 degrees to the material’s surface. You may resort to a drill stand. It has a flat metal base, two upright rods, and a mounting device that holds the drill securely and slides up and down on the rods. 

Remove the drill with pliers.

1. Clamp the channel lock pliers onto the chuck of the drill, and open the pliers’ jaws wide enough to grasp the chuck. Tighten the pliers onto the chuck. Channel-lock pliers grip the chuck. Since the pliers are metal, and the chuck is plastic, there are chances of damaging the plastic of the chuck. Try wrapping the chuck in a towel before clamping the pliers to weaken the hold.
2. Turn the pliers counterclockwise.
3. Remove the drill bit from the drill. Expect the bit to be loose and fall right out. If your fingers cannot, you can use pliers to wiggle the bit but can dull the drill bit. 

Inspect chuck

1. If your drill is brand new, return it to the store if not working. Sometimes there are issues during manufacturing that cause problems with the chuck. Get a different one before you mess around with the first one.
2. If you have had the drill awhile, retighten the chuck. The chuck can become loose, causing the drill bit to wobble during use.
3. To tighten the chuck, remove the battery pack and select the middle position of the rotation direction selector.
4. Check if the drill is spinning straight.

Repair chuck

1. If your chuck continues to give you problems, replace it. Check that the screw inside the drill chuck is tight. If it is loose, that prevents movement of the teeth. 
2. Insert the screwdriver in the drill chuck and tighten. Since the screw is in the reversed thread, turn it counterclockwise to tighten.
3. Remove the screw at the bottom. Snug the chuck against the screwdriver and loosen it by turning it clockwise.
4. Loosen the chuck and continue to remove the screw. With the screw removed, insert a big Allen key in the chuck and tighten it.
5. Insert a pipe over the Allen key for leverage and turn counterclockwise to loosen the chuck.
