I work the disk with the video on a 20-volt saw of another company, I have cut many melamines 18 and 8 millimeters (small chip on the top and clean bottom), plywood and today I cut very cleanly corian 12 millimeters without throwing (while the disk has worked enough). Since I put the disk with the video on top, the tool has skyrocketed, as if it is another machine, even its battery lasts much longer, if I say three times more I may be unfair. Before I worked it with a steel disk with a chisel that I sharpened with a file, no comparison at all.
