This Heavy-Duty Combination Sander uses a 6" x 48" belt, a 12" disc, and a 1-1/2 HP motor to tackle your tougher sanding operations. Unlike many belt-driven sanders that require adjustments, the SHOP FOX® W1712 uses a direct ball bearing drive from the motor to the sanding disc and belt to deliver a maintenance and vibration free positive torque flow. For increased sanding versatility and control, both cast iron tables accept the miter gauge.
