Besides cords and switches, (most) AC tools also have brushes that require occasional replacing. But interestingly, a few cordless tools are now available with brushless motors.

Brushless motors last far longer than their brushed cousins and the next evolution is outrunner brushless motors that have even more positives. Brushless DC sanders are now beginning to push out pneumatic sanders in a lot of commercial and industrial settings, even though they don’t last as long between overhauls the cost to run them is exponentially less than compressing air. I have brushless ROS from Festool, Mirka, and Surfprep and the Surfprep ones I prefer to my old Dynabrades which is a HUGE compliment and they are fully rebuildable.
