3500 Series. Four Flute "Tornado" Compression Spiral
Another industry first! The Vortex "Tornado" roughing / finishing tool is the fastest cutting router bit in the world! If you have the machine to do it, we've got the tool. With increased feed speeds (as much as 89 m / min or 3500 in / min) this tool will provide a clean cut on double-sided materials such as Melamine and Formica laminated particleboard. L = left hand rotation. (m) = 1/4" upcut for mortise cuts or thin materials.
