The Sawtec Grinder-Vac controls dust that slows down the operator and wastes time on unnecessary cleanup. Allows other trades to work simultaneously. Use the Grinder-Vac for concrete cleaning, planing and removal of mastics, epoxies, urethane, paint and other coatings. A new one-piece shroud is more durable, performs even better. Available in 5" or 7" hand-held or 10" walk-behind models.
