Abstract:
A metal-cutting saw having right and left sides and comprising a base and cutting teeth projecting from an edge of the base; each tooth having two side edges and a top edge defining a metal-cutting edge; each top edge being pre-ground at an inclination to form an acute angle with respect to one of the side edges and an obtuse angle with respect to the other side edge; the teeth arranged such that one-half of the acute angles and one-half of the obtuse angles are disposed adjacent the right side, and one-half of the acute angles and one-half of the obtuse angles are disposed adjacent the left side; some of the teeth being straight such that the side edges thereof are substantially coplanar with respective side surfaces of the base, and such that an end of the top edge thereof forming the acute angle defines a high end of the straight tooth, the high end being spaced farther from the base than a low end of the top edge forming the obtuse angle; the remaining teeth being set; one-half of the set teeth being set to the left, and one-half of the set teeth being set to the right; each set tooth being set by a setting angle sized to cause the top edge thereof to extend substantially perpendicular to a center plane of the base.
