Abstract
A dustless table saw with a built-in dust collection system is disclosed. The table saw uses a soft foldable seal to seal the gap between the blade slot and the blade housing, the blade housing has an internal extraction channel to maximize the dust collection. Another variation of the table saw utilizes a U-shaped blade housing with a divider. The table saw has a built-in raising/lowering mechanism to raise/lower the blade, and a built-in tilting mechanism to tile the blade. The table saw also utilizes an anti-dust blade guard to optimize the dust extraction.
