Miter saw with improved dust collection system

A miter saw with an improved dust collection system, comprising:

• a base;
• a turntable positioned on the base;
• a cutting head for performing a cutting operation, the cutting head comprising a cutting blade, the cutting head mounted on a cutting head support assembly, the cutting head support assembly comprising;
• a bevel post pivotably attached to the turntable;
• a cutting arm assembly pivotably attached to the bevel post and supporting the cutting head, the cutting arm assembly including a cutting arm assembly upper guard;
• and
• a dust collection assembly directly attached to the bevel post, in fixed relation thereto, the dust collection system comprising a dust chute having an input port, an exit port, and a funnel body positioned between the input port and the exit port, at least a portion of the funnel body extending toward an opening in the cutting arm assembly upper guard, wherein the dust chute remains substantially stationary during movement of the cutting arm assembly during a cutting operation.

A miter saw in combination with a dust collection system, comprising:

• a base;
• a rotatable table positioned on the base, the rotatable table including a table surface, a first ear extending upwardly from the rotatable table and having an opening, an opposing second ear extending upwardly from the rotatable table and having an opening in alignment with the first ear opening;
• a cutting head for performing a cutting operation, the cutting head comprising a cutting blade;
• the cutting head mounted on a cutting head support assembly, the cutting head support assembly comprising;
• a bevel post including a top portion and a bottom portion, the bottom portion pivotably attached to the rotatable table and including a first mating flange, a second mating flange, the first mating flange having an opening and the second mating flange having an opening in alignment with the first mating flange opening;
• a pin, wherein when the bevel post is positioned on the rotatable table, the first and second ear openings and the first and second mating flange openings are all in alignment, and the pin extends into the openings thereby allowing the bevel post to pivot along the pin and relative to the turntable;
• a pivot mechanism attached to the top portion of the bevel post;
• a cutting arm assembly attached to the pivot mechanism, the cutting arm assembly supporting the cutting head, the cutting arm assembly including a cutting arm assembly upper guard, the pivot mechanism arranged and constructed to allow the cutting arm assembly to pivot relative to the bevel post and toward the rotatable table;
• and
• a dust collection assembly directly attached to the bevel post, in fixed relation thereto, the dust collection system comprising a hollow dust chute having an input port, an exit port, and a funnel body positioned between the input port and the exit port, at least a portion of the funnel body extending through an opening in the cutting arm assembly upper guard and over the pivot mechanism wherein the dust chute remains substantially stationary during movement of the cutting arm assembly during a cutting operation, the input port comprising an upper portion and a lower portion, the lower portion arranged and constructed to mate with a flexible extension, wherein the flexible extension may deform when it contacts a work piece during the cutting operation, the input port positioned behind the cutting blade such that material sprayed from the cutting blade during the cutting operation is propelled through the input port and into the funnel body.
