Ideal for Polishing Projects up to 2,000 SF (200 M2)
The STI-2807 floor grinding machine is designed for small to medium-sized commercial projects and residential garage finishing. This machine is the smallest of the P/M machine line, but still produces perfect results in grinding or polishing. Its 7.5HP motor is built to last and its variable speed drive easily adapts to different grinding or polishing conditions for concrete, terrazzo, marble, and stone applications.
The moveable pocket weight system adjusts head pressure depending upon application and the standard water tank makes it easy to switch from dry to wet work. Available in 230V or 480V. Uses two tool plates (included). Recommended for project sizes up to 2,000 SF (200m2).
