  • Publication number: 20220314348
    Abstract: A dustless compound sliding miter saw with a built-in dust collection system is disclosed. The dustless compound sliding miter saw uses an extraction turbine to create a vacuum region at the end of the blade exist from the cut wood piecework, the blade housing has an external extraction channel and an external suction tube to maximize the dust collection. A retractable dust guard is utilized to confine the sawdust in the vacuum region to further maximize the dust collection. The compound sliding miter saw also utilizes anti-dust blade guard and air flow guide fins to optimize the airflow and the dust extraction.
