Cordless Rotary Tool Recommendations

Hello Folks,

I have just stumbled upon some surface rust on my 4R frame. Nothing excessive but I would like to tackle it right away.

Using a wire brush with hand is tiring, time consuming and not very efficient.
I am looking to get a cordless rotary tool with a wire brush tool to speed the process.

Any recommendations for a cordless only rotary tool and wire brush extension? Again, only cordless options. I have no place to attach a cord when working on the car.
Thanks

 

Just a cordless drill with a wire brush attachment should be sufficient.

Alternatively, there are chemical rust removers on the market and other products like Fluid Film that will stop the rust from progressing.

 

I went ahead got myself a die grinder, drill, impact driver and a rotary tool.
I think I am sorted.

 

I use an angle grinder for most places.

Corners use a wire brush attachment.
