I bought this because I have 3/4 sheet ACX, I wanted to make some cuts with the template. I had cheap beer lying around that I originally tried on a piece of scrap metal. It was like pushing a big rock uphill. He didn't want to cut very well, a lot of pressure had to be applied and the bearing failed, destroying the laser cut wooden template. So I bought this nozzle, made a new template and this thing effortlessly cuts deep in one pass. You get what you pay for.
