Get zero-measure accuracy without the cost of a rail-mount saw
Unless you own a rail-guided plunge saw, you typically have to factor in the offset measurement between the blade and the edge of the circ saw’s base when guiding it with a straightedge. With the cordless ExacTrack circular saw, you simply clamp your straightedge on the cutline, rest the base’s red portion on the straightedge, press the blade against the edge, and cut precisely on the mark. The base works with any straightedge up to 3∕4" thick.
