Using Thread Dial and Chart

Find the TPI (threads per inch) that you want to cut in the left column (see Figure 92), then reference the dial number to the right of it. The dial numbers indicate when to engage the half nut for a specific thread pitch. The thread dial chart can also be found on the front of the thread dial housing.

Threads

Figure 92. Thread dial chart.

The thread dial is not used for metric threading or for diametral or modular gear turning. You must leave the half nut lever engaged from the beginning until the threads are complete for these types of operations.

The following examples explain how to use the thread dial chart.

TPI 4-72 Divisible By 4

Use any line (position) on the thread dial, shown in Figure 93, for threading TPI divisible by four.
