Features and Benefits
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
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 non-ferrous materials.
