The large 11-3/4 in. x 48 in. table on this OES9138 Oscillating Edge Sander travels a full 8 in. in vertical height to accommodate all workpieces from tall to small. It will also tilt negative 5 degrees and out to positive 45 degrees. The cast-iron platen is a generous 48 in. x 9-1/2 in. and covered with graphite for production sanding, offering super support and cooler running to extend blade life. With 24 oscillations per minute, you can use the entire belt face without burning. A 3 HP motor powers the belt and runs a large gearbox to provide the oscillating action. The entire head pivots on a massive shaft with two sealed ball bearings for trouble-free performance. Dual dust collection ports keep the work area clean and extend the life of your abrasive belt.
