Does it come with a battery and charger?

No. It is a bare tool; battery and charger are sold separately. Any M12 battery and charger work.

It is a 5-3/8" blade trim saw, so depth of cut is limited to thin sheet goods and trim, not thick dimensional lumber.

Is it strong enough for plywood?

Yes. Owners report clean cuts in plywood, OSB and trim; it is not meant for framing.

Can I connect a shop vac?

Yes. A vac adapter is included to hook up a vacuum and cut down on dust.

All M12 batteries and chargers fit, and it is part of the M12 system of over 125 tools.

Is it worth it over an 18V saw?

If you want a light one-handed saw for trim and sheet goods, yes. For framing or heavy cutting, an 18V saw is the better fit.

About the Milwaukee 2521-20 M12 FUEL 12V 5-3/8" Cordless Circular Saw - Bare Tool

The Milwaukee M12 FUEL 5-3/8" Cordless Circular Saw is a 12V cordless saw sold as a bare tool.
