Many are interested in whether a 190mm disc will fit Answer . It gets up (I used disc 1152) without problems and cuts a board at an angle of 45 50mm And along and across. But, the mounting hole should be either 16mm (standard) or 20mm (through the ring) pressing better. On a 30mm bore (photo below), there is almost no pressing, but still sawing (a detailed report is on the drive2 website (not advertising)) I am satisfied with the tool and recommend!
I wanted to provide a visual aid to my review, so I've included some photos.
