Bottom Hand Taps are designed specifically for carrying a full usable thread to the bottom of a tapped hole. Bottom taps have 1 or 2 chamfered threads and are typically used as a secondary tap after the initial threads have been created using a Taper or Plug tap. Bottom taps may be used in both blind or through hole tapping. For a complete thread to the bottom of a blind hole a Bottom tap will be required.
