| Cutting tools: |
tungsten carbide |
| Peeling: |
not recommended or without interest |

nood |
| Note: | Peeling recommended only for decorative veneer. Sawdust may cause irritations. Some difficulties due to interlocked grain (tearing). |
| Nailing / screwing: |
good but pre-boring necessary |
| Gluing: |
correct (for interior only) |
|
