APT DW30514 4" Pneumatic Wet Air Stone Grinder & Polisher

The APT DW30514 Wet Air Grinder & Polisher is a professional-grade 4-inch (100mm) pneumatic tool specifically engineered for wet grinding, polishing, and shaping stone surfaces, marble, granite, concrete, and masonry. Equipped with an integrated water feed system, this wet air tool channels water directly to the center of the pad, suppressing harmful silica dust, cooling the cutting edge, and greatly enhancing finishing performance. Driven by a high-torque compressed air motor, it provides smooth control and durable operation in moist workshop conditions.
