Walter-Prototyp - M5x0.80 Metric 6HX Modified Bottoming Thread Forming Tap - Cobalt, Bright Finish, 70mm OAL, 13mm Thread Length, Right Hand Thread, Series D7061100

Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading to the bottom of blind holes and have 2 to 2-1/2 threads.

Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
