Slow Spiral (Low Helix) Router Bits are designed to lessen the up or down force to help keep chip outs from happening on the top of the material. Great for more brittle substrates.

Also known as Fishtail Router Bits, these are specially designed for speed and finish when working with wood. The combination of acute spiral flute shear angles with face ground helix yield high feed rates, fast plunge action, quick direction changes, deep penetration and mirror finish.
