I, unfortunately, occasionally put a hole in the wrong place and need to slot it, or need some extra clearance. I usually use a die grinder to remove the offending metal. I use a 3/8" double cut carbide bur, and the material is structural steel. My question for the experts is on proper technique. I find that the bur skips, making the tool jump around and dinging up everything around it. It seems to happen fairly randomly. I can be in the cut for quite a while one time before it starts skipping, the next time it will skip immediately. Adding a squirt of cutting fluid seems to maybe help a little bit, but it could be the placebo effect.
Is there some better technique for doing this? Tips and tricks?
This is basically the burr I'm using McMaster-Carr
Thanks,
Daniel
