We are here but you did not answer the question posed earlier. How many PCBs are you going to cut?
That kind of saw is not normally used for PCBs for several reasons: it is too 'brutal', it will tend to tear the board apart, It can not make short cuts because of the diameter of the blade and it can only cut in from board edges.
Most people use a guillotine cutter, one with a blade and lever or design boards with snap-outs, a line of holes or slots so the board can be snapped out of panel by bending it.
