Chris' Tips A while ago I was helping my brother set up a powder coating facility. We hung a lot of 1-1/2" to 2" gas and compressed air pipe, as well as a lot of conduit. This involved drilling holes in a lot of different materials. One of the guys working with us had a set of drills with this kind of point that we were using. They worked so well that the next time my brother and I were at the store we each bought a set.
They really do work markedly better than conventional drills. Use them in your cordless drill as well as your drill press.
