2100 Series. Three Flute Downcut Chipbreaker Spiral
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 the two flute tool at the same feed rate. Chipbreaker tools are recommended for hardwoods, plywoods, and dense materials where higher feed rates are required. L = left hand rotation.
