It has a steel ball and an allen screw on the top.

I couldn't get any info from SIP website.

That tool is used for installing studs, not removing them.

I'd just put two of the correct size but on the stud, tighten them together and then unscrew the stud via the lower nut. Kinda like this:

Yep! Same conclusion.

The SIP stud removers make up a practical tool set that enables the rapid fitting and removal of the motor studs found on Vespa engines.

If you have ever had to employ the potentially damaging method of tightening two nuts together on the thread of a stubborn stud to remove or fit it, you will much appreciate the ease with which these items can be dealt with using a dedicated stud removal tool. The SIP stud remover is simply screwed onto the exposed stud thread and fixed in place with the Allen key bolt and ball-bearing lock, located on the top of the device. The stud can then be safely rotated in either direction with the help of a ratchet drive or similar.

SIP - TIP : To remove the studs we recommend to heat them up a little bit. When fitting, a dab of Loctite thread lock liquid should also be applied for a secure fit!

Typical SIP BS. Never worked as an extractor. I put a nut under it and basically do the double nut way…
