Have to see your applications.

Battery operated especially 10.8V won't do much heavy works.

I don't know what you want to cut actually, but I share what type of power tools I have in hand :
Dremel 400 6/128, got it at rm750 and now rm900 at least, useful to cut MDF, light metals, setback is you still need to buy some other accessories that fit your needs.
Bosch GSB1080-2LI, got this as I need to make subwoofer enclosure, getting impact function is just in case I need to make a hole on the wall.
Bosch angle grinder with variable speed, can use for grinding cutting and polishing my car.
Angle grinder stand, attach the grinder to be a pipe cutter, max height is 1.5".
When getting wired power tools, you need to DIY own extension cable, where you can grind or cut on the road side rather in the car porch

Not at the moment since Dremel cover straight and round cuts
