What type of tooth set features a uniform set angle and alternates between left, right, and straight?

The raker tooth set is characterized by a uniform set angle, which refers to the way the teeth are positioned and angled on the blade. This set alternates between left-angled, right-angled, and straight teeth, creating a balanced cutting action that is effective across various materials. This configuration allows for efficient chip removal as the alternating angles help in guiding chips out of the cut, minimizing binding and improving the overall cutting performance.

In contrast, the skip tooth set typically has gaps between some of the teeth to reduce drag and is used primarily for cutting softer materials. The flat tooth set features teeth that are set straight without any angles, which can limit efficiency in chip removal. The variable set includes a mix of different set angles, which can create uneven cutting action and a less stable cut, making it less effective for specific applications compared to the balanced approach of the raker tooth set.
