I am planning to buy a bench drill (something like that one) to make small hole, 0.5-1.0 mm.
I recently used a Bosh drill and 1mm steel drill bit to make a hole on a FP4 fiberglass board, but the drill bit broke on the second hole drilling process.
Now, I will buy 0.6 mm drill bit but I am not sure what material it needs to be. Could anyone who knows these equipment tell me what material the drill bit should be made of, so that I can use the same drill bit for long? and what do you think about "Tungsten Carbide"?
