Share
EIBENSTOCK has long been known for its German-engineered precision and durability. Our range of diamond polishers delivers exceptional performance for both wet and dry polishing across a wide variety of materials, including natural stone, concrete, marble, terrazzo and engineered surfaces.
This guide explores the EIBENSTOCK WPN 180, EPN 1800 P, and EPO 200-3 R NT polishers, explaining what sets them apart, their best applications, and how to achieve professional-grade results with the right accessories and maintenance.
Understanding the EIBENSTOCK Polisher Range
EIBENSTOCK’s polishing range is designed for tradespeople and surface specialists who demand high torque, superior control, and reliable dust and water management. Each model within the range offers specific benefits depending on your surface type and working environment.
1. WPN 180 Wet Diamond Polisher
The WPN 180 is a wet diamond polisher designed for working on natural stone, granite, and concrete. With a 1200W motor and variable speed control, it delivers both power and precision when removing lippage or creating a high-gloss finish.
Its wet operation system allows continuous water flow to the polishing pad, which reduces friction, prevents overheating, and extends pad life. The lightweight yet durable aluminium gearbox housing enhances handling, particularly during prolonged use.
Key Benefits:
- Ideal for wet polishing of granite, marble, and concrete.
- Built-in water feed system with adjustable valve for even distribution.
- Variable speed control for coarse grinding through to fine polishing.
- Safety features include overload protection and a soft-start mechanism.
- M14 spindle compatible with standard polishing pads.
- Ideal for use with 100mm-125mm diamond discs (4” & 5”).
- Angled gearbox for a better view of the working area.
Best For:
Tile fixers, stone fabricators, landscapers, external tile installers and surface restoration professionals seeking consistent wet polishing performance on-site or in workshops.
2. EPN 1800 P Wet Diamond Concrete Polisher
The EPN 1800 P is a wet diamond concrete polisher built for heavy-duty surface preparation, smoothing, and finishing. It delivers powerful torque through an 1800W motor paired with precision speed regulation (1,200–3,700 rpm) to tackle demanding polishing jobs.
The polisher’s central water feed system maintains a clean workspace, ensuring efficient slurry removal and consistent surface cooling. The ergonomic front handle design allows better control and balance, even during prolonged sessions.
Key Benefits:
- Specifically designed for wet polishing concrete surfaces and terrazzo.
- Optimised torque transmission for efficient, smooth grinding.
- Works with 4” or 5” velcro-backed diamond pads.
Best For:
Concrete specialists, floor restoration contractors, and trades requiring high-gloss finishes on cementitious materials.
3. EPO 200-3 R NT Wet/Dry Diamond Polisher
The EPO 200-3 R NT is EIBENSTOCK’s most versatile polisher, offering wet and dry functionality for complete flexibility. Equipped with an 1800W motor and variable speed gearbox (2,000–3,000 rpm), it is suitable for both stone and concrete polishing, as well as dry finishing on engineered materials.
This model features dual water and dust management systems, enabling seamless transitions between wet and dry applications. The constant speed control ensures stable RPM even under load, while the soft-start trigger improves user safety and comfort.
A key advantage of the EPO 200-3 is its capability for precise edge work, making it ideal for use on stairs and in compact areas.
Key Benefits:
- Ideal companion for larger polishing machines
- Perfect for edge work and smaller floor areas
- Large diameter hood with cutaway for edge work
- Compatible with 4” resin and metal dot discs
- Variable speed enables work on various stone and solid surfaces
- Water feed suppresses hazardous dust
- Dust extraction improves safety and cleanliness
- Discs sold separately
Best For:
Contractors who work across multiple materials and need a reliable tool for both polishing and finishing, whether on-site or in fabrication workshops.
Choosing the Right Polisher for Your Application
| Application | Recommended Model | Operation | Key Feature |
|---|---|---|---|
| Granite, marble, natural stone, concrete, terrazzo, cement floors | WPN 180 & EPN 1800 P | Wet | Precise water control for smooth finishes & torque-optimised for heavy-duty polishing |
| Composite, engineered, or mixed materials | EPO 200-3 R NT | Wet & Dry | Dual-system flexibility with dust extraction |
When choosing your polisher, consider three core factors:
- Material Type: Harder materials, such as concrete, require higher torque and cooling efficiency.
- Surface Finish Required: Gloss finishes require variable speed control for finer pads.
- Work Environment: Wet operations keep dust down but require access to a water supply; dry operations offer convenience indoors with proper extraction.
Maintenance & Safety Tips
To keep your polisher running at peak performance:
Daily Maintenance
- Inspect water and dust systems for blockages or leaks.
- Clean polishing heads and pads to prevent material buildup.
- Inspect electrical cables and connectors for signs of wear, particularly in wet environments.
Weekly Maintenance
- Lubricate gearboxes where required (refer to EIBENSTOCK service guide).
- Check the carbon brushes and replace them if they are worn beyond the manufacturer’s recommendations.
- Test overload and GFCI functions to ensure electrical safety.
Safe Operation Tips
- Always start with lower speed settings before moving to higher RPMs.
- Use appropriate PPE: goggles, gloves, and dust masks for dry work.
- Ensure continuous water flow when wet polishing to avoid overheating.
- For dry polishing, use dust extraction units to comply with health and safety standards.
EIBENSTOCK power tools are built for reliability, but preventive care ensures long service life and consistent results.
