Elwood,
Here are some idea that have worked for me over the years.
As someone else said, having the correct size bit is important. It needs to be exactly same size as button. For cleaning out an existing hole, I have a designated bit on which I ground the tip flat so as to prevent it from going too deep. (The hole needs to be slightly deeper than the button.) Most importantly though, grinding the tip flat takes away the cutting power of bit keeping it from running all the way through the other side of lid!
When putting button in, spinning it around has always seemed to work for me; like your screwing the button into the hole. You can also put a little Teflon powder in hole or on button.
