Workability

Sucupira wood is moderately difficult to work with hand and machine tools due to its high density. It has good nailing and screwing properties, but pre-drilling is recommended. It can be stained, polished, and finished to enhance its natural beauty. The wood may have a blunting effect on cutters and tools due to its hardness.
