Ideal for Polishing Projects up to 5,000 SF (500 M2)
The STI-2420 floor grinding machine is designed for
medium-sized commercial or residential projects. This machine combines the
production capacity of a larger machine with the maneuverability of a smaller
grinder. Its 20HP motor has strong torque and its variable speed drive easily
adjusts to different grinding or polishing conditions for concrete, terrazzo,
marble, and stone applications. Available in 230V or 480V.
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. Uses four tool plates (included). Recommended for project
sizes up to 5,000 SF (500m2).
