What Is A Diamond Cut Wheel, And How Is It Repaired?

That bright, machined two-tone look on premium wheels has a name — and it needs a very different repair process to a normal painted alloy.

If your wheels have a bright, almost chrome-like machined face with a painted barrel behind it, you've got diamond cut wheels — a popular factory finish on premium and near-new vehicles.

What makes diamond cut wheels different?

The bright face is cut on a CNC lathe, giving it fine concentric machining lines and a mirror-like contrast against the painted barrel. It's not paint or a coating — it's bare, precision-machined aluminium protected by a clear lacquer coat.

Why can't you just repaint kerb damage on a diamond cut wheel?

Standard repainting can't recreate the machined look. If the face is damaged, it has to go back on a CNC lathe to be re-machined — that's the only way to restore the bright, factory finish.

How many times can a wheel be diamond cut?

Each machining pass removes a small amount of metal from the face. Most wheels can safely be done 2–3 times before the material gets too thin — we verify thickness before every job to make sure it's safe to proceed.

Is the clear coat actually necessary?

Yes — without it, the bare, freshly-machined aluminium will start to oxidise quickly. A quality lacquer clear coat is applied over every diamond cut face as standard.
