electric drill chuck type inquiry

[rojo0550]

I have a Chicago Electric(anyone have one of these?)Power Tools

VSR 3/8 inch keyless chuck drill that is need of a replacement chuck.

I checked the chuck mounting shaft for wrench flats,but can

not find any!!

I have a Jacobs chuck,1/2 inch jaw with 3/8 inch threaded

mount,but don't know if this will work on my Chiacgo Electric drill.

Both this drill and the Jacobs adapter chuck were bought from

Harbor Freight Tools some years ago.
