About this item:
- 9 x 1.25mm 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.
