Cobalt Drill

cobalt drill
bits cobalt drill for metal?

What is the best pieces of metal to pierce the cobalt? I `m drilling angle iron 4 mm just blunt 4-bit low speed with water cooling. J `I tried the Black & Decker, which were unnecessary and also titanium Bosh failed. I made a few holes left to need some very good quality that does not spoil too quickly

some carbide is the best.
