This is the largest of the Jet open-ended drum sanders and has, when used from both sides, an incredible 1,120mm of capacity with an 100mm capacity under the abrasive drum. The drum is specially balanced to reduce vibration to a minimum and has adjustments so that the drum and sander table can be set perfectly parallel to each other. The oscillating action guarantees a smooth surface and prolongs the life of the sanding belts. The variable speed feed motor drives the timber through from 3m/min down to virtual stop so that a good finish can be obtained even on the most difficult pieces of grained timber. A major feature is the 'Sand Smart' technology, which gives an automatic reduction of the feed rate to avoid excessive material removal on uneven timbers. Changing the abrasive loading is quick and easy with a self-tensioning clip device incorporated into the roller. For longer lengths of material a set of feed tables is available as an optional accessory. This sander represents a major advance in design which translates into the quality of finish that can be achieved.
