Features and Benefits
Plug chamfers are the most commonly used chamfer and designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Hand taps are used to cut threads in blind or through holes. They are used by hand or in general purpose machine operations.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous material
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
