Nice Little Sander

About Me Professional

  • Heavy Does Not Vibrate
  • Smooth Operating Machine


    Best Uses

    • Curved Shapes
    • Fine Woodworking

    I use this machine for furniture making and guitar building in my small shop. I had to replace a similar size machine made by a competitor that broke and the parts are not available. I went with Delta because I have always had good luck getting replacement parts for their tools.
