摘要： An axially mounted non-circular hole saw device follows a lateral, oscillating cutting motion to cut a non-circular kerf in a workpiece. The device adapts to variously styled power tools. The device couples to a power tool at an axial orientation through a mounting portion. The axial disposition of the device relative to the power tool enables the axial vibratory force generated by the power tool to convert to a lateral, oscillating cutting motion followed by the device. This cutting motion forms a clean non-circular kerf, offsets vibrations during cutting, and minimizes debris formed during cutting. A cutting portion has a non-circular shape. The cutting portion includes a base edge and a teeth edge. A bridge traverses the base edge for stability. A mounting portion extends perpendicularly from the bridge portion. The mounting portion includes a gap defined by slots that couple to a coupling mechanism from the power tool.
