This Heavy-Duty Combination Sander uses a 6" x 48" belt, a 12" disc, and a 1-1/2 HP motor to tackle your toughest 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.
