STI 3030 Prepmaster Grinder/Polisher

The STI 3030 Prepmaster is ideal for polishing projects greater than 10,000sf. This machine is versatile despite its weight and size. Easy one-man loading and unloading. Easy to operate. Limited operator fatigue (the operator doesn’t have to fight the machine). Interchangeable weight system converts for multiple applications. Variable speed drive for unlimited speed variation. Perfect for polishing or restoring.

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 on the 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.
