The Bosch GEX34-6N 6 In. Multi-Hole Random Orbit Sander/Polisher features the ability to use virtually any brand of sandpaper on the market because of the multi-hole design. The sander still maintains optimum dust extraction to help ensure better quality of the finished workpiece’s surface. It also provides 2X sandpaper life due to increased efficiency (this is also due to the multi-hole design that the sander can increase the life of the sandpaper). It features a microfilter dust canister with integrated paper filter and a vacuum-hose connection. The tool features a solid die-cast aluminum gear housing with exclusive dual-bearing pad mount, for less vibration. The variable-speed dial allows the user to match the speed of the sander to the workpiece and task, from 5,500 to 12,000 orbits per minute (opm). To ensure a strong grip of the disc while in use, it employs a hook-and-loop disc attachment system. The sander was designed with an ergonomic soft-grip top and body.
