What is the shelf life on a sanding belt? Support November 04, 2020 20:50 Updated Follow The sanding belts have a shelf life of approximately 2 years. It is best to store the belts in a low humidity environment. Related articles My sander runs very slowly until I place it on the work surface. Is this normal? What size wheel can I use with the 60V MAX DCG414? If I have a vac with a 1 ¼" hose that is not made by DEWALT, is there an adaptor that will connect this sander to my vac?
