This tool has worked great on my laminate countertops and backsplash. I first trimmed them flush and then used this bit to finish. This got rid of a lot of the glue and I didn't have to file much or at all. It takes some time to set up, but it's not like a drawer lock bit, which is a lot harder. I've also used an extended base on my milling machine (prevents it from falling through) and it makes a world of difference. Fast and very smooth. You can make an extended base that isn't too hard or buy one from Woodhaven who make them for many milling machines.
