Thread: Help un-doing locked keyless chuck!

Cheers,

P

A pair of vise grips attached to the drill bit and another pair (or pipe wrench like with midge has posted) clamped to the chuck, preferably on the metal part of the chuck. Or if you have one clamp drill bit in metal vise...

put the body of a drill in your vise, wrapped in a rag if you're protective about marking the case. it adds character though get out your multigrips or visegrips or something similar and attck the chcuk with that. again, try using a rag if you don't want to mark the chuck, but you may not get the grip you need. rubber might work though.

Does the chuck have a sleeve that pushes down to lock the chuck? Might be worth locking/unlocking that a few times, and giving it a light tap to jar loose any siezed parts.

A sharp tap with a rubber mallet (or the heel of your hand) in the appropriate direction will usually get any chuck undone. You can do this on large steel keyed chucks when someone has layed into it with the key to do it up and then lost the key.

I know this may seem like a silly question, but have you tried putting the drill into low gear (if possible) and reverse (if possible), gripping the chuck firmly with one hand and letting the drill do the work?

I only ask 'cos I've seen so many apprentices on-site who...

Had a similar problem with a similar dril and managed to solve without resorting to violence by gripping by hand the two bands of the chuck and pulling them apart from each other until a 1 or 2 mm gap appeared between them. and that was it... she was locked no more.
