Does this come with a battery and charger?

The drill unit is included. Confirm whether battery and charger are part of your specific kit before checkout — some configurations ship with both, others as tool-only.

Can I use this for heavy torque work like lug nuts or suspension bolts?

This is a general-duty 12V drill — fine for fastening trim, mounting brackets, and assembly. For high-torque suspension or engine work, step up to an impact driver or breaker bar.

What bits and attachments come with it?

Confirm the bit set included with your purchase. Most cordless drills ship with a basic assortment of drill and driver bits, but verify the count and types in your order details.
