Claim Text:
1. A cutting device comprising: a motor for driving a cutting blade to cut material; a shroud configured to at least partially enclose the cutting blade, said shroud defining a debris chamber into which material debris generated by the cutting blade during cutting is received; a source of vacuum in fluid communication with said debris chamber; a vacuum conduit defining a vacuum path extending between said debris chamber and said source of vacuum; a platform assembly coupled to said shroud and including: an upper member defining an upper opening for receiving the cutting blade; a lower member defining a lower opening for receiving the cutting blade, said lower member being movable between a plurality of cut depth positions relative to said shroud; and a pivot joint coupling said lower member to said upper member wherein said lower member is pivotable between a plurality of cut angle positions in which a relative angle between said upper member and said lower member is varied; a first expandable portion positioned between said upper member and said lower member, said first expandable portion being expandable in height to reduce air leakage into said upper opening as said lower member pivots relative to said upper member between said plurality of cut angle positions; and a second expandable portion positioned between said platform assembly and said shroud, said second expandable portion being expandable in height as said lower member moves between said plurality of cut depth positions relative to said shroud.
