Cordless 125 mm random orbital sanding system with extended runtime kit configuration
The Milwaukee M18BOS125-502B is engineered for professional surface preparation, intermediate sanding, and finishing applications across timber, fillers, coatings, and composite materials. The high performance motor delivers 14,000 to 24,000 oscillations per minute, enabling efficient material removal while maintaining surface control and finish quality.
The 2.4 mm oscillation diameter provides a balanced combination of stock removal and finishing precision. A six-position variable speed wheel allows adjustment according to material type and abrasive grade. REDLINK overload protection electronics enhance durability of both tool and battery under sustained operation. The integrated dust extraction box with internal filter manages airborne particles, while the supplied vacuum adaptor enables direct connection to Milwaukee dust extractors. The twin 5.0 Ah REDLITHIUM batteries provide extended runtime for continuous sanding tasks, and the M12-18C charger ensures reliable charging performance. The 16″ soft tool bag supports practical transport and jobsite storage.
