Topic tags/keywords: question

I may be the only woodworker with this problem but I have 2 12V Cordless Dewalt drills. They are lightweight, comfortable, have plenty of power but the chucks on both continue to open while drilling. Sometimes just leaving the bit in the wood or the bit falling out when I finish the hole. My wrists are not as strong as they once were and maybe I am not tightening the chucks hard enough. But I have even used a Channel Lock to hold the chuck but in a few holes the chuck opens still. Anyone else having this trouble? Am I doing something wrong?
Let me know if anyone else is having this problem.

I have that problem from time to time. I attribute it to the fact that a lot of. It now have hexagonal or other non-round shapes and so the chuck tightens the bit isn’t set exactly right and shifts when it is under load.

Most of my driver bits are Hex but all my drill bits are round. It does it on both. Seems like the brake hits pretty hard when the trigger is released and that might loosen the chuck. Wish it would quit. Every time a bit falls out, it heads directly to the floor and either buries up in sawdust or rolls under a bench. I am sure this is one of Murphy’s Laws.

I haven’t had this exact problem. Like Charles stated sometimes I don’t get the jaws seated flat on the tool. Then the tool slips and the chuck is loose. I haven’t had this problem with round shanked drills. I know we often over tighten chucks and things get sprung. My chuck says to hand tighten and listen to the little clicks. It works well. When I got my first battery powered drill motor, I would hold the chuck and spin things with the motor to tighten. I no longer do that. I try to stop people helping me from doing that with my tools.

Worth a try. I usually just hold the chuck and turn the drill on til my hand slips. I’ll try this. Glad to know there are others with similar problems.

These drills are less than 2 months old and bought brand new. If fact they started loosening the chucks almost immediately. Both drills are under factory warranty as well as Home Depot’s 90 day guarantee. Replacement chucks are $40 each if I had to pay for them. The closest Dewalt repair is a different Home Depot and they don’t stock parts. Ordering time runs 2-3 weeks. I am waiting to hear from factory. If I don’t hear from them by Wed. I’m gonna call and see what the deal is. These 2 drills are ones I got from Home Depot because the 2 Ridgid 12V were doing the same thing. Ridgid arranged for the HD store manager to swap them out and he suggested I try the Dewalts. The store has been super about this but it doesn’t solve my problem. I have 2 18Vs, a Craftsman and a Ryobi. They have never done this but both are too heavy and have too much torque for my wrists so I never use them. Why just the 12Vs?

I found If I put on a glove on the tightening hand I can get the chuck tighter.also you may not be putting the bit in the chuck straight or deep enough.
Are your bits oily,are you pressing to hard,have it in forward they can all cause the bits to come out.when yu tighten the bits turn the keyless chuck to drill it tightens better,then turn it to the setting you want.

The idea about a glove sounds like something to try. Daddywoofdawg, no problem with oily bits, most of all my stuff is old and the bits are more likely to be rusty than oily. Just got in a good set of carbide coated ones that I won on Ebay. They are marked, “Made in China” but hell, isn’t everything. I try to look for anything Made in USA first but it mostly looks like we don’t make anything here anymore. No wonder we have lots of people out of work.

Do you have the drill in the “forward or reverse” setting? If you put the direction in the “neutral” position, the motor locks and you can tighten the chuck better by hand. I have never had this problem with Dewalt or Makita drills.

I was told by the Makita repair shop many years ago, that will get worse as chuck wears. I have the problem occasionally on my Rigid drills.

Dewalt Service Center was right on. If I tighten the chuck by holding it and turning on the drill I bored 8 1/4” holes 3” deep in a pine 2×4 before the chuck loosened and the drill bit fell out. Chucking up the bit and pushing the forward/reverse button to the center position the drill locks. Then tighten the chuck by hand until you hear a click. Then I drilled the same 1/4” holes 3” deep in the same 2×4. After 30 holes I stopped, it didn’t look like it would ever loosen with drilling. The results with driving 3” #8 coated deck screws and reversing the drill to extract them. The old method let me set and remove 5 screws before the bit fell out. Tightening by hand the proper way I drove and removed 25 screws and it never loosened. Thanks to all for help and advice. Another problem solved. Guess I could have kept the Ridgid drills if I had known about this. Even the service tech at Ridgid didn’t have a solution.
