I needed a 1/4" cutter for my CNC machine to cut plywood for toys. I need to cut 3/4" and 3/8" thick boards to make toy cradles This is a lot of cuts When I use knife on the top of the plywood the edge of the cut gets split and rough which requires a lot of cleaning up after cutting.This Yonico cutter cuts leaving just a little lint on the edges which is easy can be sanded with one quick movement.
