Description
Planetary Floor Preparation System
The 8274-4 is the only grinder on the market offering 3 HP at 115 volts while operating at a 230-volt level. With variable speed and a soft start to control its amperage draw, the 8274-4 adjusts to the needs of small or large jobs. The versatility of the 8274-4 is derived from its quick-change magnetic tooling to remove thin-set, coatings, adhesives, and high spots, prepare concrete and overlays for coatings, and sand and refinish wood flooring. Polishes floors to a high-gloss shine.
