Do I need to buy batteries separately?

If you already own 12V cordless tools, this saw accepts those same batteries — no new system to buy. If you're starting fresh, plan on picking up a compatible battery pack and charger.

What materials can I cut with this?

This handles plastic trim, rubber hoses, thin steel, aluminum, and fiberglass panels. Avoid thick structural steel or continuous heavy-duty work — this is built for intermittent bodywork and bolt-removal tasks, not production cutting.

Is this saw included with a blade?

Blade is not confirmed in the package — verify before you order, or plan to grab a reciprocating blade assortment separately. Most automotive cuts use standard wood or metal blades from any hardware store.
