Bordo 2 x 0.4mm MC Bottoming Chrome Tap 4220-2.00B

2 x 0.4mm MC Bottoming Chrome Tap
Chrome Alloy Metric Coarse Bottoming Hand Tap.
Used as thread chasers to clean an existing thread.
They can also be used to create a new female thread in non-ferrous metals and plastics.
Chrome alloy taps are not suitable for creating precision, safety or critical threads.
Metric Coarse angle of thread is 60 degrees.
The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well.
Larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
The major diameter of external thread and pitch are specified by a simple numerical value (most commonly measured in millimetres).
Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
