Description
xsilicon carbide Grinding Discs, Ø 406 mm | Double Discs, Pack of 10
In short: The 10-pack of “silicon carbide ” sanding discs (Ø 406 mm ) is ideal for individual rooms, smaller floor areas, test applications, or reorders. The double-sided sanding discs fit 16-inch single-disc machines and are suitable for heavy-duty removal, rough sanding, intermediate sanding, and fine sanding on hardwood floors, wood, screed, and concrete.
This silicon carbide 406 mm sanding disc can be used on both sides and covers search terms such as “406 mm double-sided sanding discs,” “sanding discs for single-disc floor machine,” “406 mm double discs,” and “sanding discs for hardwood floors.” You can find an overview by machine, material, and grit in the sanding disc guide.

For which machines are the 406-mm double discs suitable?
Compatible with single-disc machines and 406-mm drive plates; for example, compatible systems from Lägler, Bona, MENZER, Columbus, Cleanfix, Numatic, Hako, and Taski with a matching 16-inch drive plate. The diameter, mounting, and the drive plate used are always the decisive factors.
White Superpad as a buffer under double-pane windows
For double-sided 406-mm sanding discs, a white Superpad or polishing pad (Ø 406 mm ) is used as a backing pad between the drive plate and the sanding disc. This protects the drive plate, improves machine performance, and prevents the upper sanding surface from coming into direct contact with the machine plate.
- Protection: The abrasive and the drive plate do not come into direct contact with each other.
- Smoother operation: the buffer layer dampens vibrations and reduces chatter marks.
- Even pressure: small bumps in the road are better absorbed.
- A firm, non-abrasive intermediate layer: white pads are more suitable for this application than softer cleaning or stripping pads.
Practical Tip: Do not use red, green, or black pads as a backing for double-sided discs. Always center the pad and the grinding disc.
Which " grit " is right for which application?
| grit | Recommended Use |
|---|---|
| K16–K24 | Very coarse removal, old coatings, heavy soiling |
| K36–K40 | Initial sanding and transition to intermediate sanding on hardwood floors, wood surfaces, and surfaces being renovated |
| K60 | Intermediate sanding and preparation for finer grits |
| K80–K100 | Fine intermediate sanding or sanding prior to applying oil, varnish, or other treatments |
A pack of 10 or a pack of 20?
The 10-pack is ideal for smaller projects or individual reorders. For larger areas and regular soil cultivation, the 20-pack silicon carbide double discs (Ø 406 mm ) are usually more cost-effective. If minimizing clogging and reducing dust are your top priorities, the silicon carbide sanding screen (Ø 406 mm ) is the right alternative.

Frequently Asked Questions
Do I need a white pad under double-pane windows?
Yes, using a white Superpad or polishing pad as a buffer is strongly recommended by experts. It protects the drive plate and helps achieve a more even sanding finish.
When should I use double-pane windows instead of sanding screen?
Double-disc sanders are designed for heavier-duty sanding. sanding screen are better when the priority is less clogging and cleaner dust removal.

Frequently Asked Questions
For which machines are the 406 mm grinding wheels suitable?
The discs fit all standard single-disc machines and floor sanders with a 406-mm drive plate, such as Lägler, MENZER, Bona, Wolff, and Columbus. Please check the plate diameter before purchasing.
What does "reversible" mean?
Both sides of the disc are fully coated with silicon carbide . If one side is worn out, simply flip the disc over and continue working at full grinding performance. This cuts material usage in half and saves time when changing discs.
What materials are the silicon carbide discs suitable for?
These discs are particularly suitable for mineral materials such as screed, concrete, granite, and marble, as well as for building materials such as plaster, joint compound, and Styrofoam. They are also suitable for wood, paint, varnish, and coatings.
Which grit do you recommend for screed?
For initial grinding of screed, we recommend K16–K24; for intermediate grinding, K36–K60; and for surface preparation prior to sealing, K80–K100. The silicon carbide has a particularly aggressive cut and is ideal for hard mineral substrates.
What is the difference between silicon carbide and zirconia alumina?
silicon carbide It is harder and sharper than zirconia alumina and is particularly suitable for brittle, mineral-based materials such as screed and concrete. zirconia alumina , on the other hand, is self-sharpening and more durable when working with wood and metal.
How long is the delivery time?
We ship from our warehouse in Taufkirchen near Munich within 24 hours via DHL or Hermes. Delivery within Germany takes 1–3 business days.
