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.
What’s the difference between hand pads and grinding discs?
Hand pads are used manually and offer precise control over grinding movements – perfect for small surfaces or tight corners. They’re ideal for mosaics, repairs or tile edge finishing. Grinding discs, on the other hand, are machine-driven and suited for large areas, continuous work and efficient stock removal on countertops or slabs.
What does the grit number mean (e.g. K60, K1000)?
Grit indicates how coarse or fine the abrasive is. Lower values like K60 are coarser and remove more material – ideal for chamfering or smoothing cuts. Higher grits like K1000 or K3000 are for fine finishing and polishing. Rule of thumb: the higher the grit, the finer the result.
Can these tools be used wet and dry?
Yes. Most Karl Dahm tools are suitable for wet and dry use. Wet grinding is recommended for dust control, better cooling, and increased lifespan – particularly for sensitive materials such as marble or polished porcelain.
What machines are needed for grinding discs?
You’ll need an angle grinder or polisher with M14 thread. We recommend using our backing systems (e.g. Art.-No. 50492, 50493 or 50535) to ensure a secure fit and quick disc changes.
How long do diamond hand pads last?
Made with industrial-grade diamonds, Karl Dahm hand pads are built for longevity. With correct use – applying even pressure, cleaning the pad, and using the right grit for the job – you’ll get consistent performance over many applications. Durability also depends on the hardness of the material and working technique.
Are there complete sets for beginners?
Absolutely. The large diamond grinding set (Art.-No. 50 380) and the 4-piece flexible pad set (Art.-No. 50550) offer a solid range of grits – ideal for covering rough grinding to polishing.
What can I do if grinding performance declines?
If the pad becomes clogged, rinse under warm water. For machine discs, use a diamond dressing stone (Art.-No. 20 050) to clean and re-expose the diamond surface – restoring full performance.
Are these tools safe for sensitive materials?
Yes – especially our Elox range (e.g. Art.-No. 40936) and high-grit pads (K800+) are designed for delicate stones or polished surfaces. They ensure a fine finish without scratching.
What is the best RPM for machine grinding?
We recommend a speed of 2,500 to 3,000 RPM with steady, moderate pressure. Avoid overheating or applying too much force, which can cause burn marks or uneven wear.
How do I choose the right grit for my task?
It depends on your material and the finish required. K60–K120 for coarse work or edge removal, K200–K400 for mid-stage grinding, and K800+ for polishing. Our Karl Dahm support team is happy to advise you if you're unsure.
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.
