“These have worked very well. I used them to cut openings in 7/16″ OSB siding for windows and doors. The 1/4″ unit worked very well but the bearing eventually ate it. This is no surprise as it is a very small bearing and it did quite a few feet (maybe 50-60 linear feet) before the bearing was burn” β HandyHomePro
