What is a diamond cut wheel alloy?
It’s an alloy wheel that has been put on a lathe and part of or the entire painted surface of the wheel machined off to leave a shiny alloy finish. A small part of the actual alloy is machined off to create this finish. It is then lacquered over to prevent corrosion.
You will be able to see if your wheel is diamond cut if on close inspection you see very fine lines created by the cutting machine and the appearance is very shiny. This may be harder to distinguish if your wheels are of poor quality, old, or corroded.
Not all wheels can be diamond cut as this depends on the profile of the face of the wheel, your Wheel Specialist technician will advise you if it is possible.
Are there different types of diamond cut wheel refurbishment?
Yes, there are different standards/types of diamond-cut alloy repair. You must go to a specialist that has the correct equipment/a bespoke lathe and full experience in wheel refurbishment.

Many cars are fitted with diamond-cut alloy wheels. They are a desirable, shiny wheel finish, which can be applied to the full face and lip of the wheel. When combined with a base coat, spectacular finishes can be achieved. Customers who already have diamond-cut alloys on their car may wish to repair a damaged alloy to match up with the appearance of the other wheels, or this option may be the best choice for customers looking for a smooth finish. As the top layer of the alloy is removed, chips and dents can be repaired in this way.
Corrosion is common in diamond-cut wheels, due to the difficulty of applying lacquer to a polished surface. Over time, chips allow water to get behind the lacquer, causing a cloudy appearance as the lacquer deteriorates. However, repairs are possible:
The wheel is gently blasted to remove old layers of lacquer and paint, to give a smooth surface for the repairs. Air is removed from the alloy by gently heating, and then a first stage powder coat finish is applied and cured. A second coat can be added if a particular effect is required.
Once cooled, a thin layer is cut from the alloy using a specialist CNC lathe. A clear lacquer is applied and the wheel is returned to the oven for final curing. The Wheel Specialist’s bespoke diamond cutting lathe allows for the quickest possible turnaround time.
Diamond cut alloys have a high shine finish and allow for a wide range of wheel finishes. Basecoat paint can be used to create impressive, eye-catching wheels. However, not all wheels are suitable for diamond cutting. The profile of the face of the wheel can prevent the alloy from being cut. As the process involves removing the top of the alloy, these repairs can only be made one or two times before the wheel is compromised and weakened. A specialist will inspect the wheel to ensure the right finish is applied.
If the diamond cut finish is not suitable, other wheel finishes are available. Color change or customized alloy wheels will truly give a unique look to the vehicle. After the wheel has been prepared, a powder coat finish is applied and cured, before a special or bespoke finish is applied. A wide range of colors is available, whether you want to match the alloys to your car or create dramatic effects with marbling or bright colors.
If the damage to the wheel covers only a small to medium portion of the wheel, a cosmetic repair can be used to blend the damaged area back into the rest of the wheel. The wheel is carefully prepared and then the damage is removed with sanding media or metal fillers. The profile is then sanded to match the rest of the wheel before it is covered with color-matched wet paint to hide any discernible edge. The alloy is then sealed with a lacquer to ensure the longevity of the repair.
