Art.-Nos. 50535 + 50536 – Magnetic pad incl. hook-and-loop adapter
These systems allow for quick tool changes and ensure a stable connection between machine and grinding medium.
Sharp tile edges after cutting?
A coarse diamond hand pad grit 60 (Art.-No. 50 460) reliably removes sharpness. Follow up with grit 200 or 400 for a smooth and safe edge.
Polishing marble or porcelain stoneware?
The hexagonal disc set (Art.-No. 50 724) delivers mirror finishes through multiple grit stages – from K50 to K10,000.
Narrow or hard-to-reach areas?
DSS Mini discs (Art.-No. 50609, 9-piece set) are ideal for detailed work – e.g. mosaics or internal tile cut-outs.
Diamond hand pads allow precise, controlled manual surface finishing and are especially useful for fine detail work, mosaics, tile edges, or small repairs. Grinding discs, on the other hand, are operated with machines such as angle grinders or polishers and are designed to efficiently process larger areas or long straight edges, for example on countertops or window sills. Use hand pads for precision work and grinding discs for fast surface processing.
The grit number defines the fineness of the abrasive particles. A low grit like K60 creates a rough, aggressive material removal—ideal for removing edges or leveling surfaces. Higher grit levels such as K1000 or K3000 are used for fine finishing and polishing, producing smooth, glossy results. Choosing the right grit step-by-step is crucial for achieving a perfect final surface.
Many high-quality diamond grinding tools can be used for both wet and dry applications. Wet grinding uses water for cooling and binding dust, which reduces wear, protects the stone, and increases tool life. For delicate materials like marble or polished porcelain stoneware, wet grinding is strongly recommended to avoid heat marks or scratches.
To use diamond grinding discs mechanically, you need a machine such as an angle grinder with M14 thread or a compatible polishing device. A suitable backing pad ensures a secure connection, stable handling, and quick disc changes. Flexible hook-and-loop backing pads or magnetic mounting systems provide smooth operation and improved work comfort and precision.
Diamond hand pads are coated with industrial-grade diamonds and designed for long-lasting performance. Their lifespan depends on factors such as material hardness, applied pressure, and cleaning frequency. With proper use—light pressure, correct grit progression, and regular rinsing—these pads maintain their cutting efficiency over extended periods.
Starter sets like multi-grit diamond hand pad kits or complete surface finishing sets are ideal for beginners or professionals who need a full abrasive workflow. These sets include different grit levels, allowing you to move step-by-step from material removal to fine polishing. Perfect when you're unsure which grit range you'll need.
If grinding performance decreases, the pad may be clogged with dust or stone particles. Simply rinse it under running water to clean the abrasive surface. Machine-driven grinding discs can be refreshed using a diamond dressing stone, which removes residue and exposes new abrasive diamonds, restoring cutting performance.
For sensitive materials such as marble, natural stone, or polished high-gloss surfaces, high-grit diamond pads and specialized product lines provide gentle grinding and controlled material removal. These tools minimize scratch risk and allow flawless, smooth surface finishing.
Diamond grinding discs achieve the best results at a stable speed of around 2,500 to 3,000 revolutions per minute. Applying too much pressure or using excessively high speeds can generate heat, causing burn marks or uneven grinding patterns. Maintain a steady speed and even pressure for consistent results and tool longevity.
The choice of grit depends on how much material needs to be removed and the desired final finish. Start with a coarse grit to shape or correct edges, move to medium grit for surface refinement, and finish with fine grits for smoothing and polishing. Working in multiple grit steps ensures a clean, professional finish.
Conclusion: Whether you're tackling everyday tiling tasks or high-end detail work – Karl Dahm’s diamond hand pads and grinding solutions stand for reliability, quality and versatility. From tough grinding pads to mirror-finish polishing discs and smart backing systems, professionals will find the tools they need for clean edges, flawless surfaces and exceptional results.
