What is the Mirka DEROS II 625 Sander Ø150 mm Orbit 2.5 and why choose it
The Mirka DEROS II 625 is a high-performance electric random orbital sander with a 150 mm backing pad and a 2.5 mm orbit, designed for fine, controlled sanding and pre-polishing work on a wide range of surfaces. It belongs to Mirka’s new-generation DEROS II range, offering low vibration, low noise and an ergonomic, compact design that is suitable for professional use in woodworking, automotive refinishing, joinery, composites and many other surface preparation tasks. Some technical data are taken from manufacturer documentation and reseller descriptions but may not be fully verified for your specific regional variant.
Main features
- 150 mm backing pad for efficient coverage on medium and large surfaces while keeping the tool compact and easy to control.
- 2.5 mm orbit for fine, high-quality finishes, ideal for intermediate sanding and pre-polishing steps rather than heavy stock removal.
- Direct electric drive with brushless motor (as described in Mirka materials for the DEROS II series) for consistent power, minimal maintenance and compact size. Exact internal motor details are not independently verified.
- Variable speed control with a wide rpm range around 4,000–10,000 rpm according to manufacturer brochures, allowing adaptation to different materials and grit sizes. The exact speed range of this specific unit should be confirmed in the official documentation.
- Very low vibration level (around 2.4 m/s² for the 625 model in Mirka technical leaflets) to support longer working periods with less fatigue, subject to verification for your region and configuration.
- Low noise level (manufacturer data indicates approximately 71 dB(A) in typical operation) for a more comfortable workshop environment, figure to be taken as indicative only.
- Lightweight construction with a stated weight of about 1.0 kg for the DEROS II 625 in Mirka brochures, making the sander easy to handle on vertical surfaces and overhead work; please verify exact weight for the packaged version offered.
- Ergonomic, symmetrical body shape that resembles a pneumatic palm sander, allowing comfortable use with one or two hands and suitable for both right- and left-handed users.
- Central vacuum extraction (multi-hole backing pad) designed to work with external dust extractors for dust-free sanding when combined with suitable abrasives. Performance depends on the vacuum system and accessories used.
- Compatibility with Mirka accessories such as edge protectors and pad protectors, helping extend pad life and reduce the risk of marking adjacent surfaces. Exact included accessories depend on the specific sales package.

Applications and use cases
According to manufacturer and distributor descriptions, the Mirka DEROS II 625 is intended for professional and high-demand users who require precise, high-quality sanding results. Example applications include:
- Woodworking and joinery: fine sanding of solid wood, veneers, MDF and panel surfaces prior to priming or finishing; flattening between coats of lacquer or varnish using fine grits.
- Automotive refinishing: sanding primers, fillers and clear coats; refining sanding marks before polishing when a 2.5 mm orbit is preferred for a finer scratch pattern.
- Furniture and interior fit-out: preparation of doors, cabinets, stair components and interior panels where a smooth, even surface is critical.
- Composites and plastics: controlled finishing of composite panels, gelcoat and plastic components when paired with appropriate abrasives and dust extraction.
- Pre-polishing work: when used with very fine abrasives, the 2.5 mm orbit helps minimize swirl marks and prepare surfaces for subsequent polishing stages.
These use cases are indicative and may not cover all possible uses. Always follow the safety and application instructions supplied with the machine and abrasives, and verify suitability for your specific material and process.
FAQ – Mirka DEROS II 625 Ø150 mm Orbit 2.5
-
What type of sander is the Mirka DEROS II 625?

Section 8 – Individual protection measures
The Mirka DEROS II 625 is a power tool that can generate dust, noise and vibration. The following individual protective measures are general recommendations based on typical use of random orbital sanders and are not specific, verified safety instructions from the manufacturer. Always follow the official safety instructions in the user manual supplied with the product and comply with local occupational health regulations.
- Eye protection: Wear safety goggles or a face shield to protect against dust and possible particles projected from the workpiece.
- Respiratory protection: Use an appropriate dust mask or respirator, especially when sanding materials that generate fine or hazardous dust (e.g. hardwoods, old paints, fillers). Combine with effective dust extraction whenever possible.
- Hearing protection: Use earplugs or earmuffs suited to the noise level of the working environment. Even with relatively low-noise tools, prolonged exposure can require hearing protection.
- Hand protection: Wear suitable work gloves when handling the tool and workpieces, while considering that very bulky gloves can affect grip and control.
- Skin and clothing protection: Wear work clothing that covers arms and legs, avoiding loose garments, jewelry or accessories that could be caught by moving parts.
- Vibration exposure management: Even with low vibration levels, limit continuous operating times, take regular breaks and change grip and working positions to reduce the risk of hand–arm vibration-related issues.
- Workplace measures: Ensure good ventilation, adequate lighting and a clean, unobstructed working area to minimize slips, trips and falls while using the sander.
These measures are provided as general guidance and do not replace the official safety and protection instructions supplied by Mirka for the DEROS II 625.
