Distribution Overview
The natural range of Dalbergia latifolia stretches from the sub-Himalayan tract to the southern tip of India and the island of lava in Indonesia. Its best growth occurs in the Western Ghat forests of Karnataka, Kerala, and Tamil Nadu. It has been introduced to Burma, Sri Lanka, Nepal, Nigeria, and Kenya.

Trunk diameter is 150-200 cm


They produce straight clear trunks that are 35 to 50 feet (10 to 15 m)

Product Sources
Quantities of Rosewood available on the market are rather limited because of increasing demand for rosewood. The material is shipped in the form of 10 to 36 inches (25 to 90 cm) diameter logs, most of which is converted into veneer. Rosewood is unsuitable for plywood manufacture.

Comments
General finishing qualities are rated as good

Generally strong, tough, and hard.

It is one of two most popular woods for carving and engraving, the other species being Sissoo (D. sissoo ). In the seasoned condition, Indian rosewood is two-and-one-half-times as hard as Oak (Quercus ), about twenty-five percent stronger in bending and compression along the grain, and fifteen percent stiffer.

Blunting Effect

Blunting effect on machining is fairly severe
Blunting effect on sawing dry wood is severe
Blunting effect on machining is moderate
Blunting effect on machining is severe

The wood occasionally contains chalky deposits which can blunt cutters rather severely and rapidly
