Like an engraving cutter, only straight sided. I did that to get max strength since I want to be able to cut 1/8" ply in a single pass. I tried a sprial flute cutter and they break real quick under those loads. I am astounded how strong this single lip cutter is, and it cuts a real clean slot in pine. Ive even dragged it along the work a couple times when I forgot to program a spindle on command. I tried moving faster than 15ipm and the cut path seems to have a 'swim' particularly on the spots where I plunge in to start a new cut. I expect to use a 1/8" cutter for most of the work, only using the 1/16 when I need to get into sharp corners.
