Features and Benefits
Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Extension taps are used for deep hole drilling and where a longer reach is required. They are designed with standard threads and an extended shank.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
