At the core of this orbital sander is a high-efficiency brushless motor, a game-changer for durability and performance. Unlike traditional brushed motors that wear out quickly due to carbon brush friction, this brushless motor runs cooler, quieter, and uses 35% less energy—extending its service life by 60% and ensuring consistent power delivery even during extended sanding sessions. This means less maintenance, fewer replacements, and reliable performance you can count on for years, whether you're sanding hardwood floors, furniture, or metal surfaces
