Maximize cutting efficiency and edge quality with CNC spiral compression bits engineered for high-speed routing. These bits combine upcut and downcut flutes to minimize chipping and tear-out, producing flawless edges in solid wood, plywood, and laminates. Their precision design ensures clean cuts with minimal sanding required. Why use a compression bit on a CNC router? A compression bit reduces chipping on both the top and bottom of the material, producing clean, smooth cuts in plywood, MDF, and solid wood.
