Vortex Tool Company Inc.

Chipbreaker cutting edges "break" the chips into small pieces reducing power consumption and vibration.  Chipbreakers are staggered on each flute to produce a smooth cut, but may leave visual lines on the part when used in router spindles in poor condition.  The three flute design provides a better edge finish than a two flute tool at the same feed rate.  Chipbreaker tools are recommended for hardwoods, plywoods, and dense materials where higher feed rates are required.
