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 not only covers more surface area but also increases vacuum pressure for superior dust extraction. The 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. Integrated Bluetooth technology allows you to monitor vibration levels and usage data via the myMirka® app.

Features

• Large Surface Efficiency: The 7" (175 mm) pad allows for quicker, flatter sanding of large surfaces compared to standard 5" or 6" models.
• Enhanced Vacuum Pressure: The larger pad design increases suction, improving dust extraction performance and keeping the workspace cleaner.
• High-Efficiency Brushless Motor: Patented motor technology maintains constant speed under load and offers a long, maintenance-free lifespan.
• Enhanced Speed Control: Easy-to-operate lever with bright LED RPM indicators allows for precise speed adjustments from 6,000 to 9,000 RPM.
• Leading Ergonomics: Low-profile and lightweight design provides a balanced feel and high operator comfort for long periods without fatigue.
• Smart Connectivity: Integrated Bluetooth technology allows seamless integration with the myMirka® app for real-time vibration monitoring.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery.
