I believe the lack of response is your answer. I had to look to see if they're even made, and the are, but 1/4" hex drive and masonry drilling don't normally go together. You need the percussion.
these should suit me fine. i been using a impact driver for years to drill thru block (i live in FL) to hang little things up around the house. dont need nothing crazy or big. just wanted to know if there was a better set of bits out there thats all. might not be the best tool for the job but for the size of the job its fine. i dont need them often. maybe once or twice a year.
