Features and Benefits
Taper chamfers also known as starter taps have a longer chamfer and require a less aggressive cutting action. They have 7 to 10 threads.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
