Pack of 10 double-sided grinding discs, 406 mm diameter, silicon carbide | K16-K100 for Lägler, MENZER, Bona

Pack of 10 double-sided sanding discs, 406 mm diameter, silicon carbide—the perfect quantity for renovations and workshops

Our double-sided sanding discs (Ø 406 mm) come in a convenient pack of 10—the K16 5-pack is the ideal size for medium-sized renovation projects, workshops, and professional DIYers. Available in 7 grits from K16 to K100 —the right grit for every sanding task. With a 25-mm screw hole, they fit all standard single-disc sanders with a 406-mm drive plate. As a direct manufacturer-importer, we often offer prices 30% lower than German brand manufacturers while providing comparable or better quality.

💡 Do you need a larger quantity? For large-scale projects and professional businesses, we recommend our 20-pack, which offers a better unit price.

⚡ Double-sided design — Cut material usage in half

The key advantage of our sanding discs: both sides are coated for full functionality. When one side is worn out, simply flip the disc over—and continue working at full sanding power. This effectively turns 10 discs into 20 sanding units. This saves time during disc changes and significantly reduces your material costs.

🎯 Why the 10-pack? The perfect amount for medium-sized projects

The 10-pack offers the perfect balance between usage and storage costs:

• Ideal for medium-sized renovation projects: single-family home renovations, garage floors, workshop renovations
• Convenient for professional DIYers: Enough for a complete project, without excess inventory
• Convenient order quantity: Lower upfront cost than bulk containers, requires less storage space
• Flexibility when changing grit sizes: Multiple grit sizes can be ordered simultaneously with ease

🔵 Premium silicon carbide — sharp-edged and high-performance

Our discs use open-grit silicon carbide on a sturdy fabric backing with a synthetic resin bond. Silicon carbide has exceptional sharpness and cuts through even tough, hard materials—making it particularly suitable for:

• Mineral-based materials: concrete, screed, stone, granite, marble
• Building materials: plaster, joint compound, Styrofoam
• Woodworking: Parquet, floorboards, solid wood
• Coatings: paint, varnish, old wax and protective layers

📊 The right grit for every step

Our 10-pack is available in 7 grit sizes —select the right one using the variant selector:

• K16 (Extra Coarse) — 5-pack: Maximum material removal — old screeds, thick layers of filler, paint and wax removal. Note: K16 is typically needed for specific tasks and in small quantities, so it is available in a 5-pack.
• K24 (Very Coarse): Coarse abrasion for concrete and stone floors; removal of old coatings
• K36 (Coarse): Standard coarse grit for concrete restoration and screed work
• K40 (Coarse–Medium-Coarse): Pre-sanding for parquet renovation, initial sanding of wood floors — effectively removes varnish residue
• K60 (medium-coarse): Intermediate sanding after K24/K36/K40 — removes coarse sanding marks
• K80 (Medium): Preparation for the final finish, uniform sanding pattern
• K100 (Fine): Fine sanding before sealing, painting, or coating

💡 Pro tip: For best results, work your way up from coarse to fine—for example, K24 → K60 → K100 for all concrete work, or K40 → K80 for wood renovations.

❓ Frequently Asked Questions About the 10-Pack of Double-Sided Sanding Discs

What does "double-sided" mean when referring to grinding wheels?

With a double-sided grinding wheel, both sides are coated with abrasive grit. When one side is worn out, simply flip the wheel over and use the other side—this effectively doubles the service life of each wheel and saves on material and costs.

What grit size do I need for my application?

For removing screed or thick layers, start with K16 or K24. K36 is sufficient for standard concrete grinding. K40 is ideal for sanding parquet. Then gradually move to finer grits: K60 → K80 → K100 for the final sanding before sealing or coating.

When is the 10-pack worth it—and when is the 20-pack?

The 10-pack is ideal for medium-sized projects, workshops, and professional DIYers. The 20-pack offers a better unit price and is the economical choice for floor restoration specialists, large-scale projects, and professional businesses with regular usage.

How many square meters can I cover with one sheet?

This depends heavily on the substrate and the grit size: For concrete with medium-grit sandpaper (K60), the service life per side of the sheet is typically 50–100 m². For harder or uneven substrates, the service life is correspondingly shorter. Because the sheets can be used on both sides, the effective service life per sheet is doubled.

Do I need an adapter for my machine?

A drive plate with a diameter of 406 mm is always required. In some cases, a special adapter ring may be necessary, or you can use our Superpads as a backing pad. If you have any questions about compatibility, please feel free to contact us.

Are the discs also suitable for wood?

Yes — silicon carbide also works exceptionally well on wood floors, especially for removing old sealants, wax, or varnish layers. For fine sanding of bare wood (parquet renovation), we recommend our hook-and-loop sanding discs with zirconia corundum as an alternative.

Why is K16 only available in packs of 5?

Grit 16 is needed less frequently and usually in smaller quantities—typically for spot roughing or individual problem areas. That’s why we offer K16 in a convenient 5-pack, while K24 through K100 are available in 10-packs.

How quickly will my order be delivered?

All grit sizes are available from our warehouse in Taufkirchen (near Munich) and are typically shipped within 24 hours via DHL or Hermes.

Do you also offer bulk containers or special grit sizes?

Yes—for professionals and large-scale projects, we recommend our 20-pack, which offers a better unit price. For large-scale projects and industrial applications with higher volume requirements, please feel free to contact us directly—we can accommodate custom quantities.
