Mirka® DEROS II 750 orbital sander

Mirka DEROS II 750 Orbital Sander, Full Overview

The Mirka DEROS II 750 is an electric orbital sander tailored for professionals who do not compromise on finishing quality.

Brushless motor, reduced vibrations, ergonomic grip: it handles long sessions without fatiguing the operator.

With its 150 mm pad and variable speed, it adapts equally well to automotive body sanding and wood or composite surfaces.

It is the benchmark tool for workshops that want a consistent, fast, and repeatable result.

What is the Mirka DEROS II 750 orbital sander?

The Mirka DEROS II 750 is a high-end electric orbital sander designed for finishing and sanding on flat or slightly curved surfaces. It is aimed at body shop technicians as well as woodworkers, painters, and industrial finishing professionals.

The number 750 refers to its pad diameter: 150 mm, with a 5 mm orbit. It is the most versatile configuration in the DEROS II range, balancing stock removal power and finish quality.

Mirka positions this machine as a direct evolution of the first-generation DEROS, with a revised motor, improved ergonomics, and better thermal management.

Brushless technology and brushless design: what it really changes

A brushless motor has no mechanical contacts that wear out. Result: less maintenance, no carbon brush replacements, and a significantly longer lifespan than a conventional brushed motor.

In terms of performance, the brushless motor maintains a constant speed under load. When you press down on the workpiece, the speed does not drop. The sanding remains consistent from the beginning to the end of the pass.

The heat generated is also significantly reduced. For long sessions, this is a concrete advantage: less thermal fatigue for the machine and the operator.

Compared to a brushed motor sander like the Festool ETS 150/3, the gain is felt primarily in consistency during intensive use and long-term maintenance costs.

150 mm Ø pad and 5.0 mm orbit: versatility for the sake of the result

The Mirka DEROS II 750 features a 150 mm diameter pad coupled with a 5.0 mm orbit. This intermediate size covers a wide range of applications, from body sanding to large wooden surfaces.

The 5.0 mm orbit offers a balance between aggressiveness and smoothness. It removes material more efficiently than a 3.0 mm, while leaving a cleaner surface than an 8.0 mm. Ideal for preparing a surface before applying paint or varnish.

The brushless motor develops a power of 750 W. It ensures constant torque regardless of the pressure applied, with no loss of speed under load.

The speed is adjustable from 3,000 to 10,000 rpm via an electronic dial. The machine can be easily adapted to the material being worked on: wood, metal, composite, plastic.

Model	Pad	Orbit	Power	Main Usage
Mirka DEROS II 750	Ø 150 mm	5.0 mm	750 W	Versatile, bodywork, wood, composite
Mirka DEROS II 650	Ø 150 mm	5.0 mm	650 W	Medium surfaces, bodywork finish
Festool ETS EC 150/5	Ø 150 mm	5.0 mm	400 W	Wood and paint finishing
Rupes LHR 21 Mark III	Ø 180 mm	21.0 mm	400 W	Large surface bodywork polishing

The machine's weight is contained at approximately 1.8 kg. During a workday, this lightness reduces fatigue and improves the precision of the movement.

The integrated Bluetooth connection allows speed control and monitoring of parameters via the Mirka app. A practical feature for professionals working in series.

Performance and applications: which sectors does the DEROS II 750 excel in?

The Mirka DEROS II 750 is an electric orbital sander designed for professionals who do not want to compromise on finish quality.

Its 750 W brushless motor delivers constant power, even under load. Result: a stable orbital speed from the start to the end of sanding.

It excels in automotive bodywork: paint correction, scratch removal, preparation before varnishing. The random orbital movement prevents swirl marks on lacquered surfaces.

In woodworking and cabinetmaking, it is also a leader. Panel sanding, preparation before stain or paint, furniture finishing, the DEROS II 750 handles both with a 150 mm pad.

The marine and aeronautical sectors adopt it for the same reasons: precision, consistency, and compatibility with Mirka Abranet or Galaxy abrasives.

Model	Power	Pad	Main Usage	Corded / Cordless
Mirka DEROS II 750	750 W	150 mm	Pro finishing all surfaces	Corded
Mirka DEROS 650CV	650 W	150 mm	Bodywork, wood	Corded
Mirka AIROS	-	150 mm	Light finishing, compressed air	Pneumatic
Festool ETS EC 150	400 W	150 mm	Wood, fine finishing	Corded

At Dagobert Industrie, we offer the DEROS II 750 to wood, bodywork, and industrial professionals who are looking for a reliable, powerful, and durable machine.

Mirka DEROS II 750 vs other orbital sanders: comparison table

Comparison with the DEROS II 5650, the DEROS II 125 mm, and market alternatives

The Mirka DEROS II 750 is clearly positioned in the range as the high-power 150 mm pad version. To help you choose, here is how it compares to other benchmarks.

Model	Pad	Power	Orbit	Main Usage
Mirka DEROS II 750	150 mm	750 W	5 mm	Intensive bodywork, solid wood sanding
Mirka DEROS II 5650	150 mm	550 W	5 mm	Versatile sanding, intermediate finish
Mirka DEROS II 125 mm	125 mm	550 W	5 mm	Tight areas, fine bodywork, cabinetmaking
Festool ETS EC 150/5	150 mm	400 W	5 mm	Wood finish, high-end carpentry
Rupes LHR 15 Mark III	150 mm	710 W	15 mm	Large surface bodywork polishing

The DEROS II 750 outperforms the 5650 in raw power: +200 W makes the difference on hard surfaces or those loaded with material to be removed quickly.

Compared to the Festool ETS EC 150/5, the Mirka wins on motor power. The Festool remains relevant for very fine wood finishing, but it falls short for material removal tasks.

The Rupes LHR 15 targets polishing more with its 15 mm orbit. The DEROS II 750 and its 5 mm orbit are better suited for precise sanding and surface preparation.

In summary: the DEROS II 750 is the logical choice when you want the maximum power of the Mirka range on a 150 mm pad, without sacrificing the precision of a short orbit.

Compatible accessories and recommended consumables for the DEROS II 750

The Mirka DEROS II 750 works with the Mirka Abranet and Mirka Galaxy abrasive system, available in 150 mm discs with multi-hole Velcro backing.

Abranet discs are tailored for bodywork and carpentry: their net structure ensures optimal dust extraction and a longer lifespan compared to conventional abrasives.

For sensitive surfaces or lacquer finishes, Mirka Galaxy discs offer a consistent grain and limit micro-scratches. Ideal before varnishing or polishing.

Here are the essential consumables to plan for:

• Abranet discs, P80 to P320 grits, general wood/metal/composite use
• Galaxy discs, P120 to P500 grits, fine finishes and lacquers
• Mirka 150 mm replacement backing pad, replace as soon as visible wear occurs
• Mirka vacuum hose extension, for fixed stations with centralized extraction
• HEPA filter for compatible Mirka DEROS vacuum (e.g., 1230 series)

The DEROS II 750 connects natively to Mirka vacuums via a 27 mm connection. An adapter also allows connection to the majority of third-party industrial vacuums.

At Dagobert Industrie, we list all of these consumables to allow you to work without running out of stock.

FAQ - Mirka DEROS II 750

1. What is the difference between the DEROS II 750 and the DEROS II 650?

The DEROS II 750 runs at 750 W at maximum power, compared to 650 W for the 650 version. It is therefore better suited for intensive sanding tasks on large surfaces, particularly in bodywork or on wood panels.

2. Is the DEROS II 750 compatible with Mirka Abranet abrasives?

Yes. The 150 mm pad accepts all Mirka Velcro-backed abrasives, including Abranet, Basecut, or Galaxy. These abrasives are designed to maximize dust extraction through the holes in the pad.

3. Do you need a specific extractor to remove dust?

The DEROS II 750 connects to any dust extractor equipped with a 27 mm fitting. Mirka recommends its own extractors (DEROS, DEOS) for optimal extraction efficiency, but a commercial class L or M extractor works very well.

4. Can the DEROS II 750 be used in a vertical position, on walls or ceilings?

Yes. The compact and lightweight design of the DEROS II (less than 900 g) facilitates work in a vertical position or overhead. This is a concrete advantage for finishing partitions or preparing ceilings before painting.

5. What grit range is recommended with this sander?

For coarse sanding, P80 to P120 grits are used. For finishing and primer preparation, move to P180, P240, or even P320. The DEROS II 750 handles this entire range without any problems.

6. Is the speed adjustable?

Yes. The DEROS II 750 has an electronic speed control integrated into the handle. You can adjust the rotation speed according to the material and grain used, which prevents burning the surface on sensitive materials such as lacquers or fresh varnishes.
