Designed for light-to medium-gauge materials, the Super Saber point offers one-step fastening. Its time saving performance is related to the saber-sharp piercing point with a fine-cut machine thread, which pierces the metal upon contact. Once pierced, the thread propels the screw through metal rapidly and almost without effort.
