Workability
Sawing
Ingrown stones may cause problems while processing.
Rotary Veneer Cutting
Veneer surface may be hairy or fuzzy. Good, smooth veneer can be obtained with a well-sharpened knife using a bevel angle of 20 degrees.
Sliced Veneer
Veneer surface may be hairy or fuzzy. Good, smooth veneer can be obtained with a well-sharpened knife using a bevel angle of 20 degrees.
Blunting Effect
Dulling of cutting tools is slight.
Machining
It is easy when dry, although woolly structure can prevent obtaining a smooth surface. Suitable clearance and hook angles are required to reduce the incidence of these problems.
Planing
Planing is reported to be easy.
Turning
30
Boring
Boring of this species is reported to be easy.
Nailing
It is easy to nail.
Gluing
It has a good behavior in gluing.
Sanding
Sanding of this wood is rated as fair to difficult.
Finishing
The quality of finishing is rough to woolly.
Coatings
It paints and varnishes well.
