Review on Enhanced Performance: Amana Tool 46180 K Spektra Compression – Unleashing Optimum Cutting Efficiency by Sean Webb

I got this nozzle for my CNC machine in hopes that the compression nozzle would leave clean edges on the top and bottom of the material and save me a lot of sanding compared to the spiral nozzle I was using . Unfortunately, this bit left a rough edge on both sides, doubling the grinding time. The whole point of a compression cap is to leave a clean surface on both sides, which is why they are so expensive. Even the Amana website says this bit is recommended for plywood. I don't recommend at all.
