Makita Flap Disc Silicon Carbide/ Aluminum Backing/ Flat

The Makita A-90130 is a specialized 101.6 mm (4-inch) flat-profile multi-disc designed specifically for heavy surface leveling and paint removal on concrete and masonry structures. It features premium silicon carbide abrasive grains bonded onto a rigid, heavy-duty aluminum backing plate that prevents flexing and ensures perfect planar contact with the flat work surface. Engineered to handle high thermal thresholds and abrasive concrete slurry, this high-performance disk delivers an exceptionally clean finish on stone surfaces when paired with 4-inch professional angle grinders.
