The bits are slipping in my brand new Craftsman drill press. I love it!
Except for the bits that are slipping. I am tightening the heck out of the
chuck but still the bits slip some. Any hints ? ( All of my bits are a few
years old, and I am a newbie to metal working ... ) This is usually
happening when drilling in aluminum extrusions that tend to grab the bit.


You are using the key in all 3 holes, right? If not, try that first. If the
chuck is absolutely as tight as you can get it and it still slips, take it back!
