Cordless Drill Chuck

Cordless Drill Chuck

After years of extremely hard use, I think my ½” chuck on a DeWalt 988 is starting to go. I’m looking at replacements. What is the best replacement? Looks like DeWalt has had many different chucks over the different models. Some I have liked, some I have not. Also, I have like the chucks on an older Milwaukee cordless as well. I am looking for something that is all metal, or close.

You just want the chuck or whole drill?

Looks like it had a Jacobs 700 (maybe 500 series?) which is pretty standard, haven't given me much trouble.

I tried jacking a Rohm Supra off a pawn shop drill for my Makita. They don't have a lock screw (not sure if any Dewal does) so they put them on retard tight with Loctite. I used the hex key in the chuck and smack it with a hammer trick, and thought I was going to strip the gears or break the body getting it off... and it never worked right after that. I've never used a Supra that I haven't broken to know if it's normal, but that one was self-loosening as well as self-tightening... even letting off the trigger too fast free running would make it loosen up. I liked it because the jaws don't turn with the body when tightening/loosening which is great with flat-sided bits, but it wasn't worth the trouble for me.

I picked this one up to replace the **** plastic one on my DeWalt 1/2" drill.

For a DIY like me its more than enough and the ratcheting action is awesome.

Keep in mind, the chuck on your drill is most likely reverse thread and not realizing that will cost you a few torx bits.

Chuck itself should be normal thread, if it has a lock screw then that is reverse thread. Also, the odds of removing a chuck with that halfass torx broach at the end are really bad. 10mm hex key chucked up, lay it on a bench, smack the long end with a hammer.

This is the one I am looking at. The DC988 has the retaining bolt on the inside. It is reverse thread and the chuck is normal thread.

The Milwaukee keyless chucks are made in Japan by Yukiwa, or at least they used to be. I bought a replacement double sleeve Yukiwa chuck off of ebay. It's nice and the price was right, but it doesn't ratchet as well as the single sleeve keyless chuck I have on a cordless Milwaukee drill I have. The chuck may have been older stock. I haven't found any companies selling the Yukiwa chucks under the Yukiwa name so they may only supply OEM parts to other manufacturers.

LFA of France manufactures several grades of Keyless chucks, some of them are all metal. I believe Dewalt used LFA chucks for some of their drill models at one point but I don't know whether they still do. I'm not sure of the quality. LFA's USA website.

There are also keyless drill chucks manufactured in Germany. Rohm manufactures the heavier Supra chucks which are used on some Dewalt hammer drills. Rohm also sells a lighter all steel range of keyless chuck which they call EXTRA-RV type 104-61. The chucks seem to be very similar to ones manufactured by Metabo and Bosch, so it's possible one of the other companies is actually producing them. The Metabo chucks are called Futuro Plus S1M. They're high quality but seem to have a thinner shell than the Japanese Yukiwa chucks. Double sleeve versions seem to turn up on ebay, single sleeve versions don't seem as common.
