B & B cordless chuck won't hold bit tight enough

The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.

Hi Mary,

Welcome to fixya!

This drill has a keyless chuck. To remove the bit, just turn the chuck to the right (looking from the handle to the front) to open the jaws. To put in another bit, tighten the chuck to the left to close. You have to use both hands. You will see where the ridged portion of the chuck is in two sections. Hold on to the back section with your left hand to keep it from turning while you turn the front section with your right hand.

A lot of the time I just push the button to put the drill in reverse, hold on the front section of the chuck and turn it on. It will loosen by itself. Then when you put the new bit in, put it in forward and hold on to the chuck and press the switch. The bit will be in nice and tight.

Good luck, Mary.

It is a keyless chuck. Put the drill in reverse (chuck should spin to the left when viewed from the back) and hold the main body area of the chuck with your hand while slowly running the drill. The chuck will open (unless it is broke) and release the bit. You do the opposite (slowing running the drill in forward) for tightening a bit in the chuck.

Chuck the handle of the chuck key in the chuck.Find a drill bit that fits in one of holes that the chuck key fits in.Then use a flat screw driver to lever off of the drill bit and the teeth to tighten the chuck .Use a towel and hold the drill motor,be careful not to squeeze to tight just enough to hold the drill from moving.Use a harmer and strike the chuck key and that should loosen the chuck.A 1/4 inch chuck key will work as well.If this is a key less chuck then use a small pipe wrench and hammer on the back part of the chuck with the handle left as you look at the drill.Good Luck & Thank You for choosing FixYa.com.

You can take a pair of channel locks and grab it and turn with channel locks.

Well I couldn't find a pix of your drill so I will guess that it is a typical drill. You seem to be asking a very basic question so I will start will all the basic info I can think of.

First you have to know where the power trigger is to make it go.

2nd you have to know where the forward and reverse switch is.

Now with the switch in the forward position squeeze the trigger to make it go. Then gently grab the chuck with your hand while it is going and the center Jaws should close up and come out of the chuck.

Now with the switch in the reverse position squeeze the trigger to make it go. Then gently grab the chuck with your hand while it is going and the cetner Jaws should open up and go into the chuck to a maximum point

Open the jaws enough to put the drill in the jaws then put the switch in the forward position. Put the drill in the chuck, sqeeze the trigger to make it go, and hold the chuck so the jaws close on the drill. All while keeping the drill from falling out of the chuck.

When it closes on the drill and the drill is in straight then hold the chuck as tight as you can while squeezing the trigger to make the jaws close very tightly on the drill. If you have very tender hands you might want to use gloves.

To get the drill out put the switch in reverse, hold the chuck very tightly, and squeeze the trigger to open the jaws off of the drill.

opposite of the way you put it in. Grip the chuck and put the drill in reverse and turn the chuck. or hold on tight and pull the trigger.

Keyless chucks have two parts (see pictures) when the drill is in operation both parts spin. Assuming you put the drill bit in and tightened the keyless chuck by hand, put on a work glove and grasp the part of the chuck at the front of the drill, grasp the other part and twist the front part anti clockwise.
If this does not work you can hold the front of the chuck and reverse the direction of the motor as if you were unscrewing something, then pull the trigger. If your hand does not grasp the chuck tight enough it will slip, hence the glove. If this does not work you may have to hold the front of the chuck in a vice or with caliper pliers and again the pull the trigger with the drill in reverse.
All this depends on what you used to put the drill bit in with your hand tight or held onto it with something else. Whatever was used should be enough to loosen the chuck
Hope this helps.
If it does let fix ya know.

What size bit are you using if it is real small it may be below the min sixe require for that chuck .If it is say 1/8 or larger it may be time for a new chuck .They are easy to replace open the chuck as far as you can there is a screw inside them most of them are left hand threads just back it out and tap the chuck loose with a hammer .Make sure you know the threads of your chuck when you buy the new one most are 1/2-20 but some can be 3/8-24 tpi

hi this should be reletively easy hold the end black bit with the sivler bit holde coming out not the black bit next to the yellow case on drill you hold the black part thats at end of drill by where the bit goes into not the black bit near the trigger hope i explain this ok.
Hold this bit tight then put drill in reverse then press trigger a couple of times it might be tight but shouldnt be that tight it wont undo.
1 put in reverse
2 hold black plastic piece near where drill bit goes into
3 press trigger few times
4 this should undo it allowing you to put a bit in
make sure its in reverse else you will just tighten it up more let me know if you need further assistance ok
