Wow! Did not know about the cobalt need. Don't you think it may be potentially harmful for your health (breathing it into fine powder)?

sharpening cobalt drillbits is a bit toxic, but using them to drill stuff not as its mostly a cutting motions not grinding. So no dust
Understood. I expected that drillbits could be a consequence of the drag force between the rotating parts and the "to-be-cut" parts. Indeed cobalt on metal may create far more fine powders.
Thanks for your explanation!
