What type of drill bits are recommended for drilling aluminum? Where can I buy them? Last time I tried to drill a 5/64" through 3/4" with my Dewalt pilot point bits I was melting more than I was cutting. I need these holes to be pristine and clean.
I am using my CNC machine for the drilling. I have the proper end mill cutters for the other tasks I need to perform. I just need the correct drill bit. I would the hole to be close to 2mm (approx 5/64").
Do you think I should set my tool path to 'peck drill' or just go straight through?
