Diamond grinders are powerful surface preparation tools designed to tackle a wide range of tough applications. They're commonly used for:

• Grinding and levelling concrete, screed, and natural stone
• Removing thick epoxy, cement-based coatings, or surface laitance
• Cutting through floor adhesives and paint residues
• Smoothing and finishing masonry surfaces for further treatment

Ideal for construction, renovation, and flooring professionals, REFINA and EIBENSTOCK diamond grinders provide precise control for both heavy-duty removal and fine surface smoothing.

• Efficient Surface Prep: Rapidly removes coatings, imperfections, and contaminants
• Consistent Finish: Produces a smooth, even surface ready for sealing, tiling, or coating
• Versatile Applications: Suitable for a wide range of materials and job sites
• Durable Performance: Diamond tooling ensures longer life and reduced downtime
• Dust Control Compatibility: Many REFINA and EIBENSTOCK models connect to dust extraction systems for cleaner, safer work environments

Whether you're grinding down concrete high spots or polishing stone surfaces, these machines deliver professional results with less effort.

Diamond grinders and polishers from REFINA and EIBENSTOCK can be used on:

• Concrete floors and slabs
• Screeds (traditional and liquid)
• Natural stone surfaces such as granite and marble
• Tile beds and grout
• Brick and masonry surfaces
• Painted or coated concrete

They're ideal for both internal and external use, making them a go-to solution for site prep, refurbishment, and finishing tasks.

Our range of diamond grinders is designed for dry use only and should not be used for wet grinding. They must always be connected to a suitable dust extraction system to control dust and maintain a clean, safe working environment.

Diamond polishers, however, can be used for both wet and dry applications, depending on the job and tooling. Wet polishing is often preferred for reducing dust and achieving a finer finish, especially on stone or polished concrete surfaces.

The ideal RPM (revolutions per minute) depends on the material and application, but most REFINA diamond grinders operate efficiently within the 1,400–13,000 RPM range.

Our diamond polishers have an RPM between 1500-2000.

• Lower RPMs are suited for polishing or working with softer materials
• Higher RPMs are better for aggressive grinding, coating removal, and hard surfaces

REFINA grinders are engineered for optimal torque and speed control, ensuring excellent performance across a variety of applications.
