Wow. I made skateboards out of 1/2 inch thick hardwood and fiddled with the edges - I glued the panels, planed them and then traced the outline with an MDF template which I followed with a bandsaw. After doing a rough cut, I encountered a problem. I tried a few cheap router bits that rattled and chipped and I needed to get the rough cut close enough that going to the grinder was just as easy, but it wasn't as accurate and I wanted more control. I studied them after much research and couldn't be happier or more confident. This thing is sharp and cuts clean - the bearings are smooth and it worked so well for me that I came out of the store to write this review. This item is worth more, at a fair price, and I hope it lasts a while. It looks like it's about to happen. I use it in a router table with a nice modern 3-1/2 inch router. Enjoy!
