Sia 2920 Aluminium Oxide Abrasive Belts – Wood Sanding Belts Made to Your Size
The Sia 2920 aluminium oxide abrasive belt is a proven, dependable choice for wood sanding where you want a stable cut, clean sanding pattern, and good overall value. Aluminium oxide is widely used for timber because it provides an effective balance of cut speed and finish control across common grit steps.
Whether you’re sanding solid timber, softwood, hardwood, or preparing surfaces for finishing, 2920 is well suited to workshop and trade environments where consistent results matter.
Use our Belt Calculator to order Sia 2920 in custom belt sizes and your chosen grit, ensuring the belt fits your machine and the sanding step you’re working on.
Why Choose Sia 2920 for Wood Sanding?
- Excellent all-round wood sanding performance
- Good finish control for prep and intermediate stages
- Cost-effective for routine sanding and grit stepping
- Reliable scratch pattern for consistent results
Best Applications
- General wood sanding and surface preparation
- Flattening and smoothing timber
- Intermediate grit steps before finishing

Aluminium Oxide vs Zirconia vs Ceramic (For Wood)
| Abrasive Type | Best For |
|---|---|
| Aluminium Oxide (Sia 2920) | Wood sanding, grit stepping, balanced cut & finish control |
| Zirconia | Heavier-duty sanding where longer life is needed (more common on metal) |
| Ceramic | Maximum aggressiveness and durability (typically chosen for demanding metal tasks) |
For most timber sanding and grit stepping, aluminium oxide is the sensible default because it offers predictable results and strong value. Zirconia and ceramic are usually selected when the job becomes more demanding (often metal), rather than everyday wood preparation.
