I tried these in my RotoZip tool. I had to run on highest speed due to being so sharp and aggressive. Fast cutting and you can really push these bits. I usually use 1/8" but wanted to try these. I cut a piece of 1/8" plywood first and it cut ok, but you really have to hold on or it can get away from you. Next I cut a hole in the drywall out in the garage for a new receptacle. I used the angle head attachment for better control and worked very well. Plunge cut easily and smooth cut for the box. Nice bits!
