Guhring 5535 Unequal Helix End Mill Fire coated - Flatted Shank
Up to 4-times longer tool life, vibration-free operation, improved workpiece surface quality. Guhring's 5535 Long Series Ratio End Mills offer a very simple, but highly efficient solution in order to provide optimal rigidity during the machining process. The cutting edges possess different helix angles 35° & 38°. Subsequently, Ratio End Mills have an uneven cutting edge spacing that effectively suppresses the regenerative effect.
