Compression Bits Part 2
Why use a compression bit instead of a conventional up-cut or down-cut?
Compression bits are used extensively for cutting double side laminates such as melamine or plywood. These tools can also be used on natural woods where edge finishing is a problem with standard spiral tools.
A dedicated up or downwards spiral may only give a good finish on one side of the material if the material is laminated. Where both sides of the material require the best possible finish, a compression bit is your best solution.
