Mirka DEOS II by Mirka

The Mirka DEOS II direct electric orbital sander redefines surface preparation standards by combining increased power with absolute control. Thanks to its ultra-low profile of just 4 inches (10 cm) in height and its exceptionally lightweight design, it delivers unmatched maneuverability for surgical precision, even in tight spaces or during prolonged vertical applications. It is the tool of choice for demanding professionals who refuse to compromise between finish quality and working comfort.

Engineered to protect the operator’s health, it features an advanced vibration reduction system and a built-in Bluetooth sensor that syncs with the myMirka app for precise monitoring of daily exposure. When paired with Mirka’s net abrasives and dust extraction systems, it forms the core of a completely dust-free sanding solution. You benefit from a healthier work environment, significant cleanup time savings, and a superior finish without premature clogging.

Next-Generation Brushless Motor: Delivers 20% more power and maintains a constant RPM under heavy load, requiring no maintenance or brush changes.
Ergonomic Low Profile: A height of only 4 inches and a featherlight design reduce operator fatigue while maximizing control and precision.
Precise Speed Control: Intuitive adjustment via the paddle lever, supported by clear LED speed indicators for immediate adaptation to the surface.
Optimal Dust-Free Sanding: Engineered to pair seamlessly with Mirka dust extractors and net abrasives, ensuring clean air and sharper, cleaner cuts.
Integrated Bluetooth Connectivity: Easily pairs with the myMirka app to monitor real-time vibration levels and optimize tool management.
Industrial Durability: Closed-construction motor design seals out abrasive dust, backed by continuous internal temperature monitoring.

A Range Tailored to Every Challenge

To perfectly match the scope of your projects, the DEOS II is available in several specific geometric pad formats. The compact rectangular models (such as the 343 3" × 4" and 353 3" × 5" versions) are ideal for detailed work, window frames, and architectural trim. The elongated 383 model (2.75" × 7.75") primarily targets body shop repairs and filler sanding, while the triangular Delta 663 version excels at tackling complex corners and hard-to-reach angles.

Brushless Motor

Thanks to its high efficiency patented brushless motor, the Mirka DEOS II also has plenty of power to get the job done quickly. Indeed, its performance is actually comparable to a conventional 360W 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 DEOS II 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
