I just bought a new Dewalt DWMT70786L air drill with a single sleeve keyless chuck. I have never owned one so a little confused on how chuck grips drill bit tight.
When I turn the chuck and close the jaws down on the drill bit shank the drill shaft rotates making the bit barely tight. What locks the drill from turning while you turn the chuck to tighten bit?. Is the chuck supposed to ratchet after jaws first engage the bit?
Thanks!
Yea you should feel hear a ratcheting sound locking the bit in.
