Abstract
An improved dust collection system for a miter saw comprising a hollow dust chute attached to a bevel post of a miter saw. The bevel post includes a top portion and a bottom portion and is pivotably attached to a miter saw table. The dust chute comprises an input port positioned to receive saw dust resulting from a cutting operation, an exit port and a funnel body extending from the input port to the exit port. At least a portion of the funnel body extends toward an opening located in a guard of a cutting arm assembly. The cutting arm assembly is pivotably connected to the top portion of the bevel post; wherein, the dust chute remains substantially stationary, as the cutting arm assembly is moved during the cutting operation.
