Its double-head design and 360-degree rotating cutting head make it suitable for straight lines, curves, circles, and other shapes. It can cut a variety of materials including carbon steel, stainless steel, copper, aluminum, plastic, and wood within the stated thickness limits. The included step drill bit helps create smooth starting holes, while the durable HSS blade and alloy steel construction support long service life.
