Product Description

The JET 709534 is a 3-inch spindle assembly designed as a replacement component for the JET JBOS-5 oscillating spindle sander. This assembly provides the rotating and oscillating spindle interface that accepts sanding sleeves, allowing the machine to perform contour and edge sanding on wood and similar materials. Replacement of this assembly is typically required when the spindle shows wear, wobble, or damage that affects sanding accuracy.
