inner chuck screw removal

[brokenbit]

I have a few DW953 drills and would like to do some repairs on one of them.. my problem is that the inner small screw in bottom of chuck in shot and I can not get a allen wrench to fit inside.. any idea of how to solve this problem without destroying the chuck or the drill for that matter. thanks this is my first post

got the screw off by using a endmill then all I had to do is remove rest of screw after chuck was off

I haven't heard of anyone using that method before. I'm glad it worked out!

I tried drilling first but that inner screw is hard, all I did was burn up good drill bit, cheap 5/16 endmill bit in a drill press took head of screw off real easy,
