Top 20 Dewalt DC920KA Heavy Duty Xrp 18V Cordless Drill/Driver - Page 2 Questions & Answers

sounds like you need a new motor, you can buy one from dewaltservicenet.com or ereplacementparts.com

I would start out blowing out the chuck with high pressure air because you might have some saw dust or other item causing friction that is allowing the chuck to move. Then I would spray a lot of WD-40 down the chuck to float any contaiminents up.

This is indicating the battery is too hot to charge, usually after coming off the tool right after some hard work. During the charging process the battey heats up so if you charge a hot battery, thereby making it hotter, you shorten the lifespan of the battery considerably. If you are getting a hot/cold pack delay indication on the charger, it should automatically start charging once the battery has cooled down sufficently.

Hi,
The spark you have seen inside is from the carbon brush that is arching the electric current and don't worry thats normal!

Grab the drill head as hard as you can put the drill on drill setting and the highest number setting and put it reverse

Hi,
The only way to tell if you can fix it is to take the drill apart...
Look for two wires melted together...my guess is that they got too hot and melted together inside the drill... separate and insulate and you should be fine...

could be 1 of 2 problems, the motor or the switch, I would think more the motor. you can get some idea of what the cost would be by going to dewaltservicenet.com and typing in your model number for the parts listing. But also keep in mind that Dewalt has a MAX service rate that they will rebuild the tool up to the MAX rate for it, that includes batterys (or it used to include them)

Hi Fred,
Spray penetrating oil and allow it to stand for a mins. to loosen the chuck. If you have WD-40 or other brand it will be fine.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Thank you for using FixYa. To change the chuck on your cordless drill, open the old chuck jaws to the maximum. Inside the chuck where it attatches to the drill body, there is a Philips headed bolt. Unscrew the bolt in a CLOCKWISE direction. Reverse this procedure to fit the new chuck.

Hope this helps

go to the tip section or under my profile and I have detailed instructions on how to do this. If you need more assistance please let me know before voting. Thank you

It's not unusual for Dewalt triggers to go bad and it appears you have correctly tested the trigger. You can test the motor by wiring it directly to the battery but hold on to it and only give it a short burst of power so it doesn't spin out of the case. Dewalt triggers are fairly easy to find online but shop around, they're not cheap.

Some chucks have a screw in side the chuck maybe a star-head it could be lose.

Simply because DCD940 doesn't have the hammer feature; drill/driver only :-' DCD950 does have the hammer function

If the center screw is removed counter clock wise chuck removeal

You can do it your self stay away from the cordless drills get a carbide drill bit and a tube fill it with some water so it covers the peice of porcelain you want the hole in. Ihave know idia what a 2 or 3 tiered serving piece is. But if its made out of porcelain but if you have a high speed drill and bit and you can keep the peice cool you can drill perfect holes in it. It may take some time if the hole is 1/2 inch or more depending on how thick the meteral is put a peice of wood under the peice so you don't drill through the bottom of the tube. But small holes 1/4of an inch are much quicker to do. I dought you can find anyone else to do this for you And it sounds vary artsy but this how its done with tile and you can drill perfect holes in porcelain just go slow and steady and keep it under water at all times. good luck

the chuck on my dewalt 18 volts hammer drill will not stay tight it loosenss whether i am in forward or reverse

You might need to dismantle it and look at the switch. Or the Magnito might need to be cleaned or the drill might need new brushes. Or i have just blown mine out with an air gun. and it worked.
Try these things
Good luck!
Please leave me a good comment on here for me.
Thanks

Copied from one of my posts this morning:
Remove the REVERSE-THREAD screw at the bottom of the chuck. Set the clutch collar to the highest setting, and set the gear to the slowest setting if this drill has a 2 speed transmission. Remove the battery! I have performed this with the battery in back in my noob days, and getting an allen wrench in your rib because you accidently hit the trigger will only happen once. You will never forget that experience. Get the biggest allen wrench you can fit in the end of the chuck(the shortest leg) and tighten the chuck down around it, allowing the jaws to rest and tighten on the flats of the wrench. Lay the drill on its side(chuck toward you, handle to the left, and allen wrench to the left, horizontal to the deck. Then with a hammer(soft hammer if you care about the allen wrench) quickly and deliberately hit the allen wrench in an attempt to cause the allen wrench to spin counter clockwise. Let me know if this works for you, and if not, explain what is happening.

Check electrical contacts in drill body where battery connects. Check wiring inside the drill, trigger and check also brushes. You do not have to invest 329, you can buy "body only" machine for few bucks and reuse your charger and battery packs. Juraj
