Amana Tool’s CNC Compression Spiral Router Bits are designed to produce smooth, clean cuts in double-sided melamine, laminated materials and MDF. According to the company, the bits--suitable for CNC jobs requiring high feed rates and clean finishes--feature a unique compression router bit geometry that helps prevent chip out on the top and bottom of the material by pushing chips down and ejecting them up during the same cutting pass.
