Hello Forum Members,
Looking for advice for future reference. I recently drilled a 3/4 inch (19mm) hole through a 10mm modushop aluminum front panel. Unfortunately the bit chattered terribly giving me an adequate but not perfect hole. (Rough edges).
I am assuming my main mistake was not having my work clamped down tightly. The trailing edge of my panel rested against the pedestal of the drill press so the work couldn't catch and spin, but the bit did chatter.
I used a decent drill press, decent (and expensive) cobalt bit, and aluminum cutting fluid. I had previously drilled a 3/8 inch pilot hole.
Next time I will clamp my work. Any other pointers? Thank you for helping out a construction novice.
