The Series 75 Wide Belt Sanders deliver serious results. With heavier construction than the 3760 wide belt, a fully adjustable platen, variable speed DC powered conveyor table, and large 7¼ throat opening, the Series 75 Sanders are ready to go to work in your busy shop environment. The large 75 sanding belt has 25% more abrasive surface than competing 60 belt machines. Larger sanding belts accumulate less heat and debris requiring less maintenance and fewer belt replacements.
