I disabled comments on this video because I kept getting the same stupid comments over and over from clueless people.
Following the copious number of suggestions from the gallery on reducing the speed while drilling hardened steel, I tried it out. I also tried drilling at high speed to compare.
Based on the limited data collected from these tests, I’d say that drilling at a moderate speed and lubricating yields the best results.
I turned comments off on this video because it was getting too many from people that did not watch the first video and are completely clueless as to what I was doing here.
