The Mirka® DEROS II 750X is a powerful 7-inch direct electric random orbital sander engineered for the fast and effective sanding of large surfaces. Featuring a 175 mm (7″) pad and a 5.0 mm oscillation, this model is specifically designed for construction, building, and marine production where speed and a flat finish on large areas are critical. The larger pad size covers more surface area and increases vacuum pressure for superior dust extraction performance. This next-generation DEROS II series improves upon the award-winning design with a new speed adjustment interface featuring clearly visible LED indicators and a separate on/off switch. Its high-efficiency brushless motor maintains consistent speed even under heavy load, while the low-profile, ergonomic body ensures operator comfort during extended use. This “Case” version includes a durable T-LOC Systainer for secure storage and easy transport.
