Rated 1 out of 5Â by Marinetech You need a box of these
I drill quite a lot of holes of varying sizes in boat hulls both steel and GRP, I thought I would use these for steel but as others have found they just snap so easily, I have reverted to the HSS ones which though they don't cut so well at least they don't snap off and you can resharpen them if you're old school.

Quite pricey for a drill but if you have a powerchange you need it, there is no alternative. Have used both the hss and the cobalt and found the cobalt to be well worth the extra.

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.
