Safety Speed 4375 Wide Belt Sander

The 43″ Wide Belt Sander features a 75” belt, providing 25% more abrasive surface than the smaller 60” belt machines. The larger belt translates to increased capacity, less heat accumulation, less maintenance and fewer belt replacements. With a fully adjustable platen these sanders will deliver a perfect smooth finish every time.

Offering woodworkers a maximum sanding width 43″, and available in single or three phase power, this American Made Wide Belt Sander will likely outlive you. Don’t take our word for it!  Jeff Roltgen of Roltgen Woodworks, had the following to say “Even the fussiest of finishes only need a cursory random orbit sanding after coming out of this machine.
