Description
xhook-and-loop-Grinding Wheels Made of Fined Corundum, Ø 406 mm, for Fine Grinding
In short: These Ø 406 mm high-grade corundum hook-and-loop sanding discs are designed for single-disc machines with a 406-mm hook-and-loop backing pad. They are particularly suitable for fine sanding, intermediate sanding of painted surfaces, parquet, wood surfaces, and preparatory work prior to oiling, painting, or other surface treatments.
If you're looking for 406 mm grinding wheels, hook-and-loop grinding wheels for single-disc floor machine, or high-grade corundum grinding wheels, you'll find here a finer alternative to coarse silicon carbide grinding wheels and grinding screens.

Suitable for this class of machines
Compatible with single-disc machines featuring a 406-mm-diameter hook-and-loop drive plate, such as the Lägler Single, Bona FlexiSand, MENZER ESM, Columbus, Cleanfix, Numatic, and similar machines with a compatible 406-mm hook-and-loop mounting. Please check the diameter, hook-and-loop mounting, and machine manual before purchasing.
When is high-purity corundum a good choice?
White fused alumina is a finer and more uniform abrasive option for visible surfaces and finer sanding passes. It is particularly useful when a smoother finish is desired after rough sanding, or when wood and painted surfaces need to be prepared with precision.
Grit Size Guide
| grit | Recommended Use |
|---|---|
| K60 | Intermediate sanding after coarser sanding passes, in preparation for finer grits. |
| K80–K100 | Finishing of hardwood floors, wood, and painted surfaces. |
| K120–K150 | Very fine intermediate and final sanding before applying oil, varnish, or sealant. |
| K180 | Extra-fine finishing sanding and exceptionally fine surface preparation. |
Differences from Double Discs and Abrasive Screens
These alumina hook-and-loop discs are designed for fine sanding and surface preparation. For heavier material removal on floor surfaces, double-sided sanding discs (Ø 406 mm ) or sanding screen (Ø 406 mm ) are often the better choice.
Frequently Asked Questions
Is this floorboard suitable for hardwood flooring?
Yes, especially for intermediate and fine sanding on parquet and wood surfaces when the machine uses a 406-mm hook-and-loop pad.
Do I also need a white pad?
hook-and-loop sanding discs are typically used with the corresponding hook-and-loop drive plate. White pads are primarily used as buffers for dual discs and mesh discs.

Frequently Asked Questions
For which machines are the Ø 406 mm high-grade corundum multi-hole grinding wheels suitable?
The discs fit all standard single-disc machines with a 406-mm drive plate and a multi-hole hook-and-loop system, such as Lägler, MENZER, Bona, Wolff, and Columbus. The multi-hole pattern maximizes dust extraction and keeps the sanding surface clean at all times.
What is white fused alumina, and what are its advantages?
White fused alumina is a high-purity form of aluminum oxide with a particularly uniform grain structure. It is sharper and finer than standard brown fused alumina and produces a more uniform finish—ideal for fine grinding on delicate surfaces without leaving deep grinding marks.
What applications are multi-hole grinding wheels suitable for?
These discs are particularly suitable for fine-sanding parquet, laminate, and varnished wood floors, as well as for intermediate sanding between coats of varnish. The multi-hole pattern ensures optimal dust extraction and prevents the abrasive from clogging.
What does "multi-hole" mean, and what are its advantages?
"Multi-hole" means that the sanding disc has many small suction holes distributed across its entire surface. This maximizes dust extraction directly at the sanding surface—the sanding dust is immediately extracted, the disc does not clog, and its service life is significantly longer than that of discs without holes.
Which grit do you recommend for the final polish before painting?
For the final finishing touch before the first coat of paint, we recommend K100–K120; for intermediate sanding between coats of paint, K150–K180; and for final surface preparation before the last coat, K220–K240. White fused alumina is particularly suitable for these fine grits.
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.
