I got a contractor grade milwaukee M18 cordless drill in January. I don't remember if the chuck had much or any wobble at the time. Anyways 4 months later I have so much run out/wobble that I'm shattering 5/16" drill bits. The drill bits show considerable wobble at their tips, possibly as much as 1/16". I should note that I work almost exclusively in steel. After reading endless discussions on wobble, it might just be how drills are made, but a few people have pointed out that drill bearings don't like lateral loads. I also noticed that I caused this to happen in my M12 over the course of 50 holes in 11 ga tread plate. It was dead straight when I started but wobbled by the time I finished.
If the issue is really lateral loads on the drill, how are you ever supposed to drill holes in metal since the location of the handle isn't inline with the drill axis?
Any recommendations about how I take better care of my drills and still work in metal would be much appreciated.
And before some one says it, no my drill bits are not bent. I actually checked.
