Query: Shaft is too short

I have a no name mortise machine. Bought this set for use in home shop. The shaft that goes into the chuck is too short on my machine. Make sure you can use these before you purchase them. I tried to use in a drill press as a make shift setup. I damaged the 3/8" bit and now can't use any of them or return them.
