I used this hole saw to install outdoor light boxes in my garage. I bought two thinking the brick veneer would ruin the cutting sand after a hole or two. The saw held up very well. The only victim was a masonry bat that had drilled a pilot hole. The guide tip can easily be swapped out but is meant to cut both holes I need for my garage lighting project. I would give this saw five stars if the pilot drill held up as well as the hole saw. Overall I am very satisfied with this device.
