Track saw

Track saws (often referred to as plunge saws or plunge-cut saws) are a type of hand-held circular saw which slides on a guide rail during operation. This allows the operator to perform long and accurate cuts. Track saws, unlike hand-held circular saws, plunge into the material to a predetermined depth during the cut, increasing operator safety and allowing for reduced splintering and tear-out;[1] the depth-of-cut is not fixed and can be adjusted to be just slightly over the thickness of the board being cut. This property allows a track saw to also cut shallow grooves into the work piece, if necessary.
