What I've done in this situation: if the cut is near the baseboard, OH
SO GENTLY pry the baseboard up and loose. Then use a variable speed
jig at the 2nd lowest speed with a 0-clearance blade, almost score the
floor surface by rotating the jig into the floor. The ending of the
cuts will be hidden by the baseboard (channel out the hidden edge if
necessary). Use a straightedge or mitre hand saw to complete the cuts.
Good luck
