Threading

Using the Thread Dial

If you are turning a thread expressed in TPI or with an inch pitch, once the half nut lever is engaged, it can not be disengaged. If it is disengaged for any reason, the existing thread must be picked up again by realigning the tool with the exisiting thread.

The dial position column denotes what gear on the dial engages with the leadscrew for a given pitch. The numbers in the cell correspond with the numbers on the dial face that the half nut lever can be engaged on to continue a thread. If a standard metric pitch is not listed on this table, the position 16 gear should be engaged with the leadscrew, and the half nut lever can be engaged on any number on the face.

Thread Pitch	Dial Position 14	Dial Position 15	Dial Position 16
0.175	1, 2
0.35	1, 2
0.4			1, 2, 4
0.45		1
0.7	1, 2

Additional Metric Thread Pitches

As of writing, we do not have the appropriate change gears for many of these additional thread pitches.
