Thread mill feeds and speedschart

If you measure the neck diameter (thinest part of thread mill) and find the feeds and speeds for that size endmill. That should probably be a more aggressive setting depending on your depth of cut.

@langmuir-daniel @langmuir-mike : Can you guys add these information to the feeds and speed table you published previously? That would be very useful for future reference instead of digging into the forum

I don’t use them because unless you’re running substantial production- being locked into one pitch is really disadvantageous. If you got them run them. Chatter likely won’t be an issue. No different than a rougher with high axial engagement.

@langmuir-daniel Is there any guidance on S&F for standard/full profile threadmills (IOW - not single profile)? I have a few but I’ve been I’ve been afraid I would chatter them to death.
