What can I say? That works great. I might give an update after using it after a few months or a year but compared to other bits I've used it's great. I don't understand how this can break. I don't see any signs of it dulling after about two hours of drilling the cedar boards. It seems easy to sharpen when it eventually becomes dull. Using a Makita 1 1/4 PS Palm Router, I cut out the wooden signs.
