Designed for applications that require variable speed, the SG-20VS is the workhorse of the Spirogrinder line. Its size and power make it the ideal choice for those who are serious about their work. This machine is great for jobs from small to medium square footage as well as the occasional large job. Easy to use and built to handle the punishment that may come its way.

The Spirogrinder system combines a unique 3-head counter-rotation system with specially designed diamond discs to grind dirt and paint off of concrete surfaces to leave a smooth, open concrete finish. Our unique dust control system makes the spirogrinder the perfect choice for all dust free applications.
