Features and Benefits
Bottoming chamfers have 1 to 2 threads. Plug chamfers have 3 to 5 threads. Taper chamfers have 7 to 10 threads and are typically used as a starter tap. They all can be used for threading blind holes.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
