The APT M321 triple piston scabbler delivers precision concrete prep – three pistons at 3,000 blows per minute remove coatings, rust, laitance and light buildup without damaging the base surface, and roughen concrete for bonding and overlays. This model runs the extended handle; the extended handle keeps the operator comfortable and further from the surface on larger areas. 14.8 CFM at 90 PSI, 10 lb, 21 in long, with easy-change interchangeable pistons in carbide or cobalt low-spark.
