Deburring sharp edges on aluminium
When deburring aluminium edges, you look for the balance between rounding and keeping the corner. Do you want to round the edge, or must the sharp corner remain? That determines which product you choose.
Which product suits your workpiece
Want to round the edge? Choose the SA wheel in the 6SF version. If the sharp corner must remain, Cibo Bristles are the right choice.
SA6SF
Ideal for deburring and rounding the edge in one step.
- Silicon oxide grain
- Long service life
Cibo Bristles
Ideal for removing burrs without losing the sharp edge.
- Removes burrs efficiently
- Consistent result, also on CNC machines

How to deburr aluminium in 3 steps
Choose: round or keep the corner
Want to round the edge? Choose the SA6SF. If the sharp corner must remain, choose Cibo Bristles.
Work with light pressure
Let the wheel or brush do the work and move evenly along the edge.
Check the edge
Check that all burrs are gone and the edge is the same everywhere, especially if the workpiece will be painted or anodised afterwards.
Frequently asked questions about deburring aluminium
Why is it important to deburr aluminium?
Sharp edges and burrs are dangerous during handling and can make assembly more difficult. They also cause paint or coating to adhere less well to the edge. Deburring makes the workpiece safer and ready for further finishing.
How do you deburr aluminium and round the edge?
Use the SA unitized wheel, for example in the 6SF version. With it, you deburr and round the edge in one step. The wheel also has a long service life.
How do you deburr aluminium without losing the sharp corner?
If you want to keep the edge, choose Cibo Bristles. They remove burrs efficiently while keeping the sharp edge.
Can you deburr aluminium on a CNC machine?
Yes. Cibo Bristles are made of thermoplastic-bonded abrasive and deliver a consistent result with a long service life. This makes them very suitable for CNC machines and a good alternative to steel wire brushes.
Should you deburr aluminium before painting or anodising?
Yes, preferably. On a sharp edge, the paint layer stays thinner and can be damaged or peel off more quickly. Deburring first gives you an even layer and a more durable result.
