The main objective of this work was to evaluate the effect of the bandsaw teeth parameters on the production and quality of the sawed wood of eucalyptus. It was evaluated the effect of two tooth pitches (57,15 mm and variable pich: 50,8 50,8 50,39 50,71 60,03 60,35 mm ), two hook angles (26 and 27o) and two gullet depths (22 and 25,4 mm) on eucalyptus sawed wood. Ten logs of Eucalyptus grandis x Eucalyptus urophylla clones, fifteen years old were used. Logs were classified in two diameter classes with five logs with diameter between 25 to 34 cm and other five logs with diameter between 35 and 47 cm. Board thickness was measured in five points in both sides. Cut deviation was not affect by log diameter as mentioned in the literature. Variable pitch did not improved wood quality. Band saw with hook angle iqual to 27o and gullet depth of 22 mm or 25,4 mm provided positive cut deviation. The smallest thickness variation was found for bandsaw with gullet depth iqual 25,4 mm and hook angle iqual 27o. The largest cut deviation was observed with variable pitch and hook angle of 26o. The productivity was not affected by the six treatments.
