Abstract
A portable cutting apparatus. The apparatus includes a motor and a cutting blade driven by the motor. A protective housing encloses at least a portion of the cutting blade. A vacuum impeller is disposed in a vacuum housing to generate airflow to move dust and debris created by the cutting blade into a removable vacuum bag. At least one vacuum tube directs the airflow from the protective housing to the vacuum housing. The motor operates both the cutting blade and the vacuum impeller. A bellows interconnects the protective housing and a lower platform. The lower platform pivots relative to the cutting blade about a pivot axis that is outwardly spaced from and parallel to a cutting plane defined by the cutting blade.
