Great sander for any shop

By Jon Kelly

from Prescott, Michigan

Verified Buyer


  • Easy paper changes
  • Easy to operate
  • Good dust collection
  • Large Capacity
  • No snipe on ends
  • Quiet
  • Small Footprint


  • mobility
  • No tool or paper storage

Best Uses

  • Drawer sides
  • Quartersawn Oak
  • Raised panels
  • Table top glue-ups
  • Unusual Grains

Great for large glue-ups and small ones. Just love the finish and time savings. Works great on quartersawn Oak, NO tearout and NO snipe. Fantastic feed rate adjustment, and heavy duty belt. Sized just right, not too big or too small. In my little shop, it's hard to justify having a dedicated sander and giving up the floor space but it's well worth it when I consider the time savings and consistent finish. It would be nice if it were more mobile
