Review: quality bit provided an awesome finish and lasted longer than expected. - I didn't expect this bit to work as well as it did rounding over a fresh cut hard granite edge with just a standard router. It let a nice smooth finish, and lasted longer than expected. I used a hose on trickle to keep it and the material cool, and strongly recommend that. It did take a while on the hard granite, and I used two bits to do twelve feet, but very happy with the result.
Review: Shank size is large - Works good but need a full size router to use. Used on terracotta tile to create bull nose
