I don’t know where you shop but DeWalt is cheaper than Milwaukee and Makita. Project Farm tests show Milwaukee as usually best but trades wins against Makita.

So no, DeWalt isn’t overpriced. It’s cheaper and less quality. Neither is Milwaukee equivalent to DeWalt. Milwaukee/Makita are better, sometimes incredibly better than DeWalt but at a much higher price.

For example a drill with battery on Amazon is:

DeWalt: $99 Makita: $149 Ryobi: $73 Milwaukee: $144

At Home Depot and Lowes, the price difference between DeWalt and Milwaukee is even bigger.
