A track saw (aka ‘plunge saw’) is a type of circular saw that makes precise straight cuts by means of a metal track (aka ‘guide rail’). Both corded and cordless models are available. Because of its design you get consistently clean, chip-free cuts in both solid wood and sheet goods. Tracks are available in different lengths. Friction strips on the bottom of the track provide sufficient grip for most sawing tasks, eliminating the need for clamps. However, specialty clamps that lock into the track are available when you do need to secure the track. Because the saw blade is constantly square to, and inline with, the track, cuts are not only extremely accurate, but free of burning and saw marks. Additionally, the tracks have flexible plastic splinter guards along the cutting edge that virtually eliminates chipping. Unlike a circular saw, a track saw moves up and down by means of a spring-loaded hinge, which makes plunge cutting easy and safe. Most models also have an integrated riving knife to prevent kickback.
