Brushless vs Brushed Cordless Tool Motors
A brushless motor uses electronic commutation instead of carbon brushes, typically giving 20-50% more runtime per charge and longer motor life, at a real price premium.
A brushless motor uses electronic commutation instead of physical carbon brushes, which means no brush wear, less friction and heat, and typically 20–50% more runtime per charge plus a longer motor lifespan than an equivalent brushed motor. The honest tradeoff is cost: brushless tools and kits carry a real price premium over brushed equivalents. For occasional homeowner use (a few projects a year), a brushed drill is genuinely adequate; for daily or heavy use, brushless pays for itself in runtime and tool life.
