MODEL 7C
Jones Model 7 Cordless takes the excellent and ease of use of the Model 7 and makes it even better.
Designed to sit on the shoulder of the blade and not the teeth themselves, thus leading to less tooth wear. Can be supplied with a grit wheel or with a diamond wheel depending on which style of teeth you use.
Simply attached your own 3/8” chuck drill to power the shaft and you’re ready to go.
