Keruing

Heartwood ranges from a light to medium yellowish brown to a darker reddish brown. Overall appearance and grain patterning is rather homogenous and bland.Grain is generally straight to slightly interlocked. With a medium to coarse texture and moderate natural luster.

Diffuse-porous; exclusively solitary; very large pores in no specific arrangement, very few; parenchyma diffuse-in-aggregates, vasicentric; medium to wide rays, spacing normal.Varies depending on species, though generally reported as moderately durable; moderate to poor insect resistance.

Generally easy to work with hand or machine tools, though silica present in the wood tends to dull cutters. Also, resin can exude from the wood and build up on tools and also make wood finishing difficult. Movement in service is fairly large.
