What is the difference between the drill and the impact wrench in this kit?

The drill is for making holes in wood, brick and concrete and for light screwdriving. The impact wrench delivers high torque in short blows for tightening and loosening bolts and nuts.

Can the impact wrench remove car lug nuts?

It is marketed for high-torque fastening, but no torque figure is given. Check your vehicle's lug nut torque spec and whether the wrench's stated output clears it before relying on it for wheel work.

Do both tools use the same battery?

Yes. The kit is built on a shared 21V battery platform, so the same pack and charger serve both tools.

Is this kit suitable for drilling into concrete?

The drill is described as handling concrete and brick walls, but it is a cordless drill, not a rotary hammer. For frequent or deep concrete holes, a dedicated hammer drill or rotary hammer does the job faster.

Is this a good choice for a professional?

It fits home and light renovation use. Professionals who run tools daily usually prefer established brands for service, spare batteries and proven durability.
