I have a corded dewalt drill I use in the garage that I bought last year from lowes. Costed me 60 bux. I was sick of replacing batteries on all of my old cordless ones
Anyways, the chuck on this thing slips with any decent amount friction caught up on the drill bit. Is it possible to change these thjnfs over to a keyed chuck?
Looks similar to this one

Should be possible. Open the chuck wide and look for a flathead screw inside at the bottom. Remove it. Then chuck up a 3/8 allen wrench by the short end. Swat the end with a hammer to break it loose and it should unscrew.

Order a genuine Jacobs chuck with the proper thread from a place like MSC and replace it.

I do this with every drill I have.

Keyless chucks shouldn't slip. If it does, then replace it with a non defective or quality keyless chuck.

No need to go back to an old fashioned keyed chuck.

It's fine till I drill through steel. Then it usually slips

Ya the locking screw is normally left hand thread.
Had to do the same to my drill, bought a Jacobs off amazon and am happy

Going back to a keyed chuck is like trading in a BMW for a Model T because the starter went bad and you prefer to hand crank.

Not all keyless chucks are the same. Get a good one and don't look back.

I'd take a model t over a BMW anyday!!!

I don't think I'm getting this chuck off. The inside screw is completely striped

Should be mentioned that the screw is left hand thread, and I have always just chucked the allen wrench, laid the drill on the floor and pulled the trigger, the impact of the allen smacking the ground knocked it loose without having to go grab a hammer.

Thank you!! I decided to put an Allen key in and turn the drill on and it was violently smacking the ground and all of a sudden "swing" the chuck came flyin off

Now to find the right new one for it

For true, not arguing the convenience of a hand chuck, just the difficulty of getting and keeping them tight. One commercial electrical contractor I know buys leather gloves by the box; his left hand glove always wears out twice as fast from trying to hold the hand chucks tight enough.

When tight matters, key chucks are usually still found and the heavier duty and more industrial the application, the more likely a key chuck is still to be found.

In more than fifty years of chucking drills, I've had far more hand chucks slip/wear out than key chucks. Some of my WWII-era drill presses still have the original Jacobs keyed chucks. Some of my five-year-old hand chucks used 1/100th as much are toast.

I don't care what anyone says keyless chucks are a pain in the ***. They are good if you are drilling and screwing in wood. You can buy quick change holders. I have very strong grip and no matter what I do I can't get the things to keep from slipping when I drill in metal. I have drilled thousands of wholes in my life. In high school I drilled and taped holes by the thousands every day. I bought a drill press with a keyless chuck and it slipped. That was in the 50's . I pulled the shaft and put a taper on it so I could put a chuck with a key on.

When you use a key you need to put it in every hole and tighten. Do not use just one whole. You will not get an even grip.

Pox on keyless chucks. I have changed every tool. If you want good keyless chucks just send me an e. You can have them for the cost of shipping.

The only good keyless chuck is an Albrecht, and it would cost more than the drill itself if it were possible to mount it.

Sure, I'll take all the Albecht/Rohm chucks you're willing to send me and will be glad to pay shipping:beer:

The problem isn't keyless. The problem is that the manufacturers use the lowest quality keyless chucks they can find. (ex: Chinese Jacobs Multi Crafts)

Hey guys I got er accomplished. Stopped by grainger and they set me up with this jacobs.
When I get home u think I should put some loc tire on the threads?
Btw I have no idea what I drilled out but there's no set screw on my drill. There's not really a threaded hole on the shaft

That sure looks like a threaded hole to me. If the drill is reversible you need the screw. If it's forward only then you don't.

Why don't you look up the parts diagram of the drill from the model number.

I've got a dewalt 18v cordless with what looks like sintered inserts in the jaws , (it might be a rohne chuck) , anyways it's always been a good one
I've also got their angled drill with the worlds nastiest chuck , I'd change it but the reverse switch has also crapped out , so it's now my last resort drill

I'm almost positive it's not. The directions for the drill say nothing about a screw to undo to take the chuck off
That tiny hole looks a little larger than it actually was because I took a drill bit inside of it because I thought there was a set screw haha

Some of those chucks have carbide insert jaws to help resist slippage.

And in the directions how to remove the chuck it says nothing about a center screw

I figured since this one doesn't have a set screw I'd put a little blue loc tite on the threads

I'm really curious what holds that chuck onto the shaft when you put it into reverse??

Did Dewalt use LocTite on the old chuck instead of the screw??

I've never seen a reversible drill without a L.H. screw except for those that are taper fit.

No idea but I ended up putting some red loctite on it instead

Here is a pic of a new one from Home Depot. That isn't a screw in there. It's actually just the bottom of the chuck itself
