DT-DIATOOL 4 Inch Dry Diamond Polishing Pads — 8-Pack 100 Grit, Flexible 4mm for Granite & Marble

DT-DIATOOL 4-inch dry diamond polishing pads (grit 100) are a flexible, water-free solution for refining and restoring granite, marble, quartz, and tile surfaces.

If you need an efficient way to smooth rough edges, remove light scratches, or prepare stone surfaces for a higher gloss without using water, these pads offer a convenient alternative. Designed for dry polishing, the set contains eight 100mm (4") pads with a thin, 4mm flexible profile that conforms to curved or uneven stone. They work well on countertops, stairs, tiles, and other stone installations where a portable, low-mess approach matters.

How do these pads perform when polishing hard stones like granite?

The 100-grit diamond surface removes material quickly and levels small imperfections on hard stones. Because the pads are engineered for dry use, they produce minimal mess and allow rapid progress when removing chips or prepping surfaces for finer grits.

• Coarse 100-grit diamond for efficient material removal
• Durable bond for extended life on dense stone
• Thin 4mm construction adapts to edges and contours
• Recommended 2500RPM for best balance of speed and control

Can I use these pads on marble, quartz, and tiles without water?

Yes — these pads are formulated for dry polishing across a range of natural and engineered stones. Dry operation reduces the need for water hookups and cleanup, making them suitable for interior and jobsite use where water is impractical.

• Works on marble, quartz, ceramic, porcelain, and tiles
• Less slurry and faster cleanup compared with wet methods
• Flexible design helps maintain contact on uneven areas
• Max safe speed 4000RPM — avoid exceeding the limit

What equipment and speeds are recommended for safe, effective use?

These pads attach easily to angle grinders, rotary polishers, or backing plates sized for 4-inch discs. Following the recommended speed range helps protect the pad and the stone while delivering consistent results.

• Recommended operating speed: around 2500RPM for control
• Maximum allowable speed: 4000RPM — do not exceed
• Use appropriate backing plate or pad holder for 100mm diameter
• Wear PPE: dust mask, eye protection, and hearing protection

How long will each pad last and how should I care for them?

Pad lifespan depends on stone hardness, pressure, and speed; denser stones and heavy pressure shorten life. Store pads flat and clean them occasionally with compressed air or a soft brush to remove abrasive dust and extend usable life.

• Pack of eight pads provides multiple passes or projects
• Light brush or air blast clears embedded grit after use
• Rotate through pad set to balance wear across jobs
• Avoid overheating by using recommended speeds and moderate pressure

Who this is for: These DT-DIATOOL 4-inch dry diamond polishing pads suit professional stone fabricators, countertop installers, tile setters, and serious DIYers tackling restoration or finishing work. They are ideal when water access is limited, when you need a coarse 100-grit stage to remove nicks or shape edges, or when a compact, flexible pad is needed for irregular surfaces. If you require finer finishing, this 100-grit step pairs well with higher-grit pads in a multi-stage polishing sequence.
