Does it come with blades?

The kit includes the tool, two 2.0Ah batteries, a charger and a case. Blades and sanding pads are generally not included, so budget for an accessory set.

Will my other M18 batteries work in it?

Yes. It runs on any Milwaukee M18 battery, and larger packs give longer runtime at the cost of more weight.

Is it good for sanding?

It sands well in corners and against edges, but the small batteries limit long sessions. A larger M18 pack is a better match for heavy sanding.

How does it compare with a corded multi-tool?

It gives up some raw power to a corded tool but works anywhere without an outlet. For heavy continuous use, a corded model still has the edge.

Can it cut drywall and pipe?

Yes, with the right blade. It handles drywall, PVC, copper pipe and nails, which is why plumbers and electricians favor it.

Is it worth it over a cheaper 12V multi-tool?

If you already own M18 batteries, the shared platform and stronger motor justify it. For light occasional use, a smaller 12V tool is easier to handle.
