Description

Ideal for Polishing Projects up to 20,000 SF (2,000 M2)

The Prep/Master STI-4430  floor grinding machine is an ideal choice for project sizes up to 20,000 SF (2,000m2). Quite unexpectedly for its 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 4430 is available in 220V and 480V, as well as with a 25HP motor. Uses eight tool plates (included) and twenty-four tools.
