Prep/Master® 3030 (Electric Model)

Ideal for Polishing Projects up to 10,000 SF/ 929 M2

The Prep/Master STI-3030 is an ideal choice for project sizes up to 10,000 SF (929 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 220V and 480V, as well as with a 25HP motor. Uses four tool plates (included).
