SOURCE: shake the drill to make it work

Sounds like the battery is not making a good connection inside the drill handle. Clean the contacts inside the handle where the battery plugs. Clean the contacts on the battery. If there are any springy tabs in either of these places, pry them up slightly to increase the pressure between the contacts.

Clean with wire brush, sandpaper, electrical contact cleaner.

If this doesn't work, get back to me and we'll go to the next step.

Test the brushes by catching it in a stalled condition when you have it triggered, then rotate it slightly. If it takes off suspect the brushes or a dead segment on the comutator.

If it doesn't respond to this, then consider the VSR trigger... open it and test by bypassing it when in stalled condition...

Dewalt DCH253 drill loses power


It's common for the brushes to pop out of place causing partial contact to the armature . If there not damaged you can simply slide the brush and holder back in place or replace if damaged. .another common issue is the leads going to the motor can become damaged . Most of the time you can clean the terminals and reattach them to the motor .if loose use pliers to carefully squeeze the terminals to the contacts on motor . .I hope that helps !

Drill has very little power/ even with full charge battery/ maybe brushes? thanks


It could be but more likely the motor itself is just worn out. I would replace the motor assembly as they do wear out on these models. Here is a link to the parts diagram.

I have a dewalt 1/2 drill only used it once and it makes a knocking noise when using it. lost my receipt so can't return it, can you tell me what might be wrong with it . thanks


I'm pretty certain the brushes are loose and hitting against the armature. The brushes are held in place by a spring that looks like a ball point pen spring. The brushes are replaceable on that drill. I would take it to Lowe's or Home Depot and they should be able to provide brushes for it that you can replace yourself.
