Ideal for Polishing Projects up to 10,000 SF (1,000 M2)
Our most popular model! The Prep/Master STI-3030 floor grinding machine is an ideal choice for project sizes up to 10,000 SF (1,000 m2). Despite its heavy weight and size, this grinder is extremely easy to operate due to the smooth operation of the STI rotary gear system. Its 30HP 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. The 3030 is available in 230V and 480V. Uses four tool plates (included) and twelve tools.
