摘要： A power tool includes a table structure defining a blade slot, a blade positioned within the blade slot, a motor assembly to rotate the blade, and a dust chute assembly. The dust chute assembly surrounds at least a portion of the blade and includes a plenum for receiving airflow scavenged from operation of the motor assembly and redirects the airflow to convey dust and debris from operation of the blade to a discharge outlet.
