What is included with the FLEX FX4111-1A kit?

What work is this oscillating multi-tool intended for?

The product information names cutting, trimming, plunge work, sanding, grinding, and scraping. The suitable accessory depends on the task.

Does the tool work with other FLEX 24V batteries and chargers?

FLEX claims compatibility across its 24V batteries, chargers, and tools. Check accessory fit separately, since the listing does not detail blade compatibility beyond naming the 3D Starlock connection.
