Similar to the Festool Rotex series of sander, the Makita BO6050J has a traditional random orbit mode as well as a gear-driven coarse sanding mode called Robo-orbit. This mode allows you to quickly strip a surface or remove stock far faster than you could with a normal random orbit sander. Think of it more like a powerful grinder type action but still with an orbital pattern to prevent scratch patterns. Order yours today from The Tool Nut -
