Katalox has a heartwood with a dark reddish brown to nearly black color. The sapwood is a pale yellowish white color. The grain is straight and it has a fine texture. The end grain is diffuse-porous. Katalox is generally a very durable wood, but it depends on the species. It can be difficult to work on because of its high density and moderate to high blunting effect on cutters. The wood can be troublesome to glue because of its high density and natural oils.
