DUSTLESS ONE-STROKE CUT-THROUGH SAW
20200230720 · 2020-07-23 ·

A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members having proximal and distal ends. The saw system further includes a handle assembly coupled with a bearing member, which is mechanically engaged with the sliding members, and an elongated blade fixedly attached to the bearing member. The elongated blade includes a serrated cutting edge that is acutely angled relative to the support surface.
