Summary: It is heavy duty and his heavier than the average cirlular saw. I just used it cutting pressure treated 6x6 timers and cut through them like butter. The guide is different than I am used to. Your drawn line does not align with with the edge of the slot thus the blade.
Summary: LIke other reviewers have noted, the bottom of the base is machined poorly with sanding or grinding grooves perpendicular to the direction of cut. The electric brake doesn't really stop it instantly like the B&D Super Sawcat I have owned & used for the past 28 years.
