A device for attachment to an existing portable circular saw with a fixed upper blade guard having a front and rear terminus a top surface, an inside outer surface, and an outside outer surface extending between a front upper blade guard opening and a rear upper blade guard opening respectively defined by the front and rear terminus of the fixed upper blade guard, comprising:
- a housing having a lower surface and a downwardly extending flange extending below said lower surface from a first side of said housing, said downwardly extending flange having an inside surface which with said lower surface defines a receiving channel designed and arranged to receive the fixed upper blade guard therein with said housing extending beyond the rear terminus of the fixed upper blade guard to define a rear end, and said lower surface defining a rear vacuum aperture located near the rear blade guard opening when the fixed upper blade guard is received within said receiving channel;
- a vacuum source connection means for connection to a vacuum source attached to said housing in fluid communication with said rear vacuum aperture;
- removable attachment means affixed to said housing for removably attaching said housing to the fixed upper blade guard.

- a housing having a concavely curved lower surface, a rear end and a front end;
- a flange attached to a first side of said housing and extending radially inward from said concavely curved lower surface, said flange having an inside surface which with said concavely curved lower surface defines a receiving channel designed and arranged to receive the fixed upper blade guard therein;
- a front vacuum aperture extending through the concavely curved lower surface;
- a vacuum source connection means attached to said housing for connection to a vacuum source;
- fluid communication means attached to said front vacuum aperture and said vacuum source connection means for providing fluid communication therebetween;
- and
- removable attachment means affixed to said housing for removably attaching said housing to the fixed upper blade guard wherein said front vacuum aperture is located near the front upper blade guard opening when the fixed upper blade guard is received in said receiving channel.
