i realized that drilling had this effect with heat when i started making these blocks. what i do is i just drill about 2 lines of holes at a time and then let everything cool down while i dip the copper in a bowl or water. as the bit sizes get bigger, i dont have to do it anymore, just stop once in a while to wipe off the shavings and spray some more WD-40 in the holes.

also the faster i can go down, the less it will heat up, so i just try not to keep the bit at one stop for too long and kinda have to go up and down a few times on each hole.
