About this item:
-
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.

Firstly the delivery was fast and the transaction simple. Thanks. The Bosch is well built, has the power to tackle some thick growth and you can get a second battery 8amp by redemption free. Happy I selected the bundle and the dealership.
Great company, great support, great product.
As with all of the rosewood marbles tools, great quality. Now I just need to stop the students from damaging them.
No problem with the whole transaction
Good price easy transaction and good delivery

Took was exactly what I needed to complete my project. Great quality. Left a beautiful smooth hole.

Very good 👍
Item in excellent condition, good price, speedy delivery.
Arrived well packaged and works great, good doing business with yourselves
Due to a lack of support for Jet bandsaws in my country, finding a replacement tire for mt 18” saw was difficult!! I nearly got scammed by some mob in Europe until I found Beyond Tools. This tire is perfect and won’t be supplied by the manufacturer out of America so for me this has been the best solution
