rescuing a drill chuck

johncal2009

I have a old drill that has burned out, so I am going to dispose of it, However the Chuck is Ok and I would like to save it. It is one you would use a chuck key with, can anybody tell me how I would remove it from the drill?

Open it up fully and if you look down inside there should be a screw, remove that.
After that you need to hold than mandril tight and the chuck should screw off, left hand thread from memory.

Thank you very much Brian, this helps a lot

The screw in the centre of the chuck is also LH thread iirc. so be careful not to damage it by trying to turn it clockwise.

Surely if it's a LH thread it will loosen when turned clockwise?

Thanks Sean, very useful advice but as the contributor above states to turn the screw clockwise would loosen a left hand thread screw, is this not so?

M.T.D

You state "older drill" if the drill does not have a reverse it could be a screw in type.
To unscrew these. insert the chuck key as normal but instead of turning it, hit it sharply with a hammer in the direction the drill normally turns.
The chuck will then usually unscrew.

Sorry john, meant anti-clockwise! (as you'd be tightening it further)
