Melamine Part 1: Making Clean Cuts Melamine is notorious for chipping out on the back side when cutting. In this video I share my tools and techniques for creating clean cuts on both sides of melamine. The blade I use in the video is a Freud LU97R010. I did not make it clear in the video, but the images of the cuts you see are of the backside of the melamine, this is where the chip-out occurs. A proper melamine blade makes the back side of the cut look as good as the top side. In Part II I will show you how to apply edge banding.
