Abstract
A drum sander having a fin for deflecting airflow around the drum and directing dust and debris to a dust collecting outlet. The fin includes a first section at a first angle and a second section at a second angle that directs air movement generated by the operating drum toward the dust collecting outlet. The free edge of the fin is shaped to wrap partially around the drum in two helical inclined planes. A tool free adjustment of parallelism may be provided. The workpieces are pulled through the sander rather than being pushed through. Lightweight materials reduce stress on the assembly. Heat is dissipated by the configuration and material of the drum.
