Proline 89457 Diamond Polishing Pad 125mm Grit 3000 for Granite and Marble

The Proline 89457 diamond polishing pad is a professional-grade accessory engineered for the precision finishing of natural stone surfaces. With a diameter of 125mm and a fine grit size of 3000, this pad is specifically designed to deliver a high-gloss finish on granite and marble. It integrates seamlessly with standard angle grinders, providing consistent material removal and surface refinement for stone masonry and restoration tasks.

Advantages

This diamond polishing pad offers exceptional durability and efficiency when working with hard natural stones. The high-quality diamond abrasive ensures a uniform finish, reducing the time required for manual surface preparation. Its versatile design allows for both wet and dry operation, providing flexibility depending on the specific requirements of the project and the equipment being used. The integrated velcro backing facilitates rapid and secure attachment to backing pads, allowing for quick transitions between different grit levels during the polishing process.

Suitable for

• Achieving a high-gloss finish on granite and marble surfaces
• Smoothing sharp cut edges on stone slabs
• Chamfering edges for a professional aesthetic
• Refining flat stone surfaces during restoration projects

When it may not be suitable

This pad is not intended for heavy material removal or aggressive grinding, as the 3000 grit is specifically formulated for final polishing stages. It is also not suitable for use on soft materials like wood, plastic, or metal, as the diamond abrasive is optimized exclusively for stone applications.

Key specifications

• Diameter: 125 mm
• Grit size: 3000
• Attachment type: Velcro
• Compatibility: Angle grinders
• Operating modes: Dry and wet
• Material application: Granite and marble

How to use

To achieve the best results, ensure the stone surface is clean and free of debris before starting. Attach the pad to a compatible velcro backing plate on your angle grinder. Begin the polishing process by using coarser grit pads first, gradually progressing through the grit range until reaching the 3000 grit pad for the final polish. Maintain steady pressure and consistent movement across the surface to ensure an even finish. If a mirror-like gloss effect is required, follow up with dedicated buffing overlays after completing the 3000 grit stage.

What to consider before purchase

• Ensure your angle grinder supports a 125mm diameter accessory
• Verify that you have the necessary backing pad for velcro attachment
• Consider purchasing a full set of grit sizes for a complete polishing sequence
• Check if your project requires wet or dry polishing conditions

Usage recommendations

For optimal surface quality, always follow a sequential polishing process starting from the lowest grit (50) and working up to the 3000 grit pad. Use buffing pads as a final step if a high-gloss mirror effect is desired.
