Pitch Selector for Structural Material This selector can be used to easily find the correct pitch for cutting profiles and tubing. Step 1. Select the maximum dimension of the part to be cut on the horizontal scale. Step 2. Note: It is not advised to use a finer pitch as the overfilling gullets will break the teeth. Cutting in Bundles For round tubing double the single wall thickness and find the correct pitch. For square and rectangular tubing take into consideration the maximum distance to cut in the bundle and the combined wall thickness.
Then check on the vertical column the wall thickness measured and find the advised pitch in the table. Step 3. For faster cutting, the next larger pitch can be used.
