The 4375 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 7 1/4" 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.
