Properties

Hardness (Janka): 1910; 48% harder than Northern Red Oak.

Dimensional Stability: Below average (change coefficient .00396; 7% less stable than Red Oak).

Durability: Dense and very strong; high resistance to wear.

Workability

Sawing/Machining: Difficult to work because of high density and irregular grain; carbide tooling recommended.

Sanding: Sands well, but dust can stain fabric and wall treatments.

Nailing: Good holding ability.

Finishing: Red color can bleed into some finishes — a problem when mixing species.
