    The Right Point for Every Project

    Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
