changing my drill chuck

[sonny]

What is the correct procedure for changing the keyless chuck on my dewalt drill? I keep breaking torx bits and can't get the chuck loose.

Hi Sonny. The torx screw inside the DW987 chuck is reverse-thread, meaning that you'll have to turn it clockwise to remove it. That might be why you're breaking torx drivers. eReplacementParts has a helpful article and video about removing drill chucks here:

The DW987 chuck is threaded on, not taper fit. I hope this helps.
