KEO woodruff keyseat cutters are extremely versatile profile milling cutters. Although originally designed to mill standard woodruff keyseat, they now satisfy a variety of applications from milling slots to milling threads. Carbide-tipped tools feature cutting edges of carbide for wear resistance and a steel shank for toughness. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
