Item #: 82416181Brand: Reiff & NestorModel #: 45792 Features and Benefits Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and bl ind holes. They have 3 to 5 threads. Spiral point taps are used for tapping through holes. They have a flute geometry that shoots chips ahead of the cutting action to reduce loading and clogging within the flute. 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.
