Mirka® DEROS Orbital Sander has a soft start function, a built in electronic motor brake and a smooth, easy to operate lever to control motor speed. Thanks to its high efficiency brushless motor, this electric sander also has a plenty of power to get the job done quickly. Its performance is comparable to a conventional 500W electric machine and that ensures it maintains a constant speed even under heavy load.

The unique symmetrical design makes it just as comfortable whether it’s being used in the left hand or the right hand and the longer body provides the option of a two-hand grip. Mirka® DEROS is equipped with a backing pad, which has a central air inlet. This results in improved air flow and helps extract dust away from the center of the tool even faster.

  • The most compact, ergonomic and powerful sander in its class
  • Brushless motor to minimize maintenance
  • Lower vibration, compared to market standard

The 6 inch (150 mm) Mirka® DEROS sander can be converted to a 5 inch (125 mm) sander with the use of the 5 inch balanced backing pad for the 6 inch (150 mm) sander (915GV28-130G) sold separately.

Please note that the 5 mm orbit model is the most popular and versatile model. It sands material much quicker. On the other hand, the 2.5 mm orbit model is designed specifically for finishing purposes.

Brushless Motor

Thanks to its high efficiency patented brushless motor, the Mirka DEROS also has plenty of power to get the job done quickly. Indeed, its performance is actually comparable to a conventional 500W electric machine and that ensures it maintains a constant speed even under heavy load. The innovative design of the brushless motor means there are few wearing components so it is low maintenance, ultra-reliable and has a long lifespan. In contrast to conventional electric machines, the Mirka DEROS also features a ‘closed construction’ which prevents dust from entering the motor where it can cause wear and damage.

Mirka Backing Pad

The Mirka backing pad is optimized for using the Abranet abrasive for sanding without dust. The backing pad helps you get the most out of your net abrasive. Available in various levels of softness, depending on what your sanding. The fresh air channels on the pad support an increased airflow and thanks to that the dust is removed efficiently.

myMirka App

Mirka added an integrated vibration sensor and Bluetooth® technology to their most popular electric sanders and developed an app to follow-up the measurements. Thanks to myMirka you also access a lot of tool data and enjoy many digital benefits, as for example, warranty registration through the app. More information

What distinguishes a Mirka Deros 2.5mm sander from a Deros 5.0mm sander?

The key difference lies in the eccentricity of the device, which directly influences the sanding process. A larger eccentricity (e.g., 5.0mm) enhances the material removal capability, although it may affect the sanding finish. On the other hand, a lower eccentricity (e.g., 2.5mm) promotes a better sanding finish but is less effective for material removal. In short, a 2.5mm orbit sander is ideal for finishing work, while a 5mm orbit sander is more versatile and can handle various types of sanding, ranging from light to medium finishing tasks.

Therefore, if your sanding tasks primarily focus on finishing, investing in a Mirka Deros 625 CV sander with a 2.5mm orbit would be highly beneficial. If you desire a more versatile model where extraction is more important than the finish, the Mirka Deros 650 CV, the most popular Mirka product at Ardec, would satisfy your needs. Note that the Deros sander can be connected via Bluetooth to monitor and control daily exposure to vibrations.
