Questions about this item

Will the 1/2-13 UNC mandrel work with my existing Helicoil 2288 series installation tool?

Yes, the 2288-8 mandrel is designed for 1/2-13 UNC inserts and fits the corresponding Helicoil installation tooling for that thread size.

How do I confirm the 2288-8 mandrel is installing the 1/2-13 inserts to the correct depth?

The mandrel's threaded length matches standard 1/2-13 insert dimensions; when the tool bottoms out or the tang breaks off at the notch, the insert is seated correctly.
