It might because these tools have tried to make standard fits. But, the best thing to do is get a DeWalt blade (inexpensive one for cutting) and try it. If that blade fits then this should also.
The blade would not have been tested by the manufacturer on Rigid tools.
The thickness for the DWA series is: DWA4219 - 1/8", DWA4220 - 3/16", DWA4221 - .089", DW4240 -.081" DWA4243 -.073" , DWA4341-.050" and the DWA4242 is 0.73" in thickness.
The grout removal baldes are : DWA4219, DWA4220, DWA4221, DWA4240, DWA4241, DWA4242 and DWA4243.
