What is alloy wheel diamond cutting?

Diamond cutting is a specialist alloy wheel refurbishment process that restores the machined metal face found on many modern alloy wheels.

During the process, the wheel is mounted onto a precision CNC lathe, where a thin layer of metal is carefully removed from the wheel’s surface to refinish the exposed metal areas. The wheel is then protected with a clear lacquer coating to help prevent corrosion and maintain its appearance.

Diamond cutting is commonly used to repair kerb damage, corrosion, and cosmetic wear on wheels with this distinctive two-tone finish.

How much does alloy wheel diamond cutting cost?

The cost of diamond cut alloy wheel refurbishment in the UK typically ranges from £90 to £150 per wheel, depending on the wheel size, level of damage, and whether additional repairs are required.

Wheels that require extra preparation work, such as corrosion removal, welding, or straightening, will increase the final cost. Premium or larger wheels can also fall towards the higher end of the price range.

How long does diamond cutting wheel take?

Diamond cut refurbishment usually takes 24 to 72 hours, depending on the garage’s workload and the condition of the wheels.

This is because the process involves stripping the old finish, repairing damage, precision machining the wheel face, and then applying protective lacquer, which must then fully cure before the wheel can be refitted.

Some specialist providers may offer faster turnaround services, but diamond cutting generally takes longer than standard cosmetic repairs.

How many times can a wheel be diamond cut?

Most alloy wheels can be diamond cut two to three times during their lifetime.

Each time the wheel is machined, a small layer of metal is removed, so there is a limit to how many times the process can be safely repeated. A specialist will inspect the wheel and measure tolerances to confirm whether another diamond cut refurbishment is possible.

If the wheel has already been cut multiple times, a painted or powder coated finish may be recommended instead.

Can I paint my wheels instead of diamond cutting them?

Sure, many drivers choose to convert diamond cut wheels to a painted or powder coated finish.

This involves removing the machined face finish and refinishing the entire wheel in a solid colour, such as gloss black, anthracite, or silver. This option can be more durable and easier to maintain, particularly for drivers who regularly experience kerb damage or corrosion issues.

Is diamond cutting only available at garages?

Diamond cutting requires specialist CNC machinery, so the process is most commonly carried out by garage-based alloy wheel refurbishment specialists.

However, advances in technology mean that some mobile providers now offer diamond cut repairs in certain areas, using compact machining equipment installed in mobile workshops. Availability of mobile diamond cutting will depend on your location.
