 Product Description

The STI-2415 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 15HP 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).
