- Summa Routing systems with universal bits can route aluminum covered foam board, however the wear is rather high. Specialized (bit) stores have specific bits for aluminum.
- Some brands offer boards with a different alu coversheet thickness that impact the lifetime of the bit.
- Bits that have been routing aluminum should not be used on other materials.

- Higher speeds are possible but affects the edge quality.
- If the speed is set too low, the foam will melt and cause issues.
- The edge quality is far better if the object is routed in one single pass. However, this may leave a lot of chips and debris on the table.
- When routing in two passes, make sure the first pass is already in the bottom aluminum sheet. If not, the melting foam may cause issues.
- A cleaning pass is discouraged. The small offset may cause cracking of the lacquer on the aluminum sheets.
