> I am no t sure about the best cutter, but have an almost free solution to the problem. I have been using a homemade cutter for PCBs recently, and it works fairly well. I have a number of solid carbide PCB drills that have broken, leaving a 1/8" diameter carbide drill rod about 1" long. I chucked these in my lathe and used an angle grinder with abrasive blade to grind a point on the end of the rod.
I have been told that carbide dust is quite dangerous. Are these
concerns overblown? Do you take precautions?
