This tip works great! First use was to cut some holes for a kayak hatch, this bit cut smoothly through plastic and had no chatter, just a clean easy cut. I've also used it on a few wood projects and it works just as well, leaving clean, smooth cuts that require little to no sanding. It's also very sharp, you can feel the edge of the blade so be careful when removing it from its protective case. I am very happy with the performance and will order more for my wodshop.
