My seldom used as a hobbyist ROHM keyless chuck, that has spent most of it's life using a #3 drill in it in my mill, always worked great until a few days ago. I put in the #3 drill and turned on the mill at the same speed it always runs at and the drill bit fell out. So I stopped the machine and stuck it in again and it fell out again after I switch the power on. Eventually it stayed in there long enough to do the job (drilling into delrin) that it always does. I thought maybe my mill was vibrating a bit as I pushed my thumb on the draw bar and made it less noisy but that really didn't solve anything. What would cause my keyless drill chuck to all of a sudden loosen up when I power up my mill? Is that how they normally fail?
