Bosch Powerchange HSS Cobalt Pilot Drill
What Have Bosch Done?
Had the Bosch kit for a few years, the holesaws used to be really good, no they don't seem to be man enough anymore.
This pilot drill seems to slip out of the arbor which is really annoying.
Also, as the other reviewers say, these drill bits do break quite easily. So its best to drill a pilot with a slightly smaller HSS bit then go through with the Bosch pilot.

Always breaks i have gone through 6 or 7 in the last 2 years ! I like the bosch powerchange for cutting holes in ceilings for downlights etc it is a good piece of kit but the powerchange pilot drill is so brittle and is the weak link.
