- Also known as a jig saw.
- Cuts with an up and down motion and is ideal for cutting curves and irregular lines.
- Usually can cut through 1” hardwood and 1-1/2” softwood. More powerful models can cut up to 2-3/4” thick in wood and 3/4” in aluminum and some can cut thin steel.
- Quality machines operate at approximately 3,000 strokes per minute.
- Generally, better machines also have longer strokes, often 1”.
- The scrolling feature on some saws allows the user to turn the blade by means of a knob on the top of the tool instead of turning the whole tool.
- Good quality jigsaws will also have features on the base that allow them to cut at an angle. An antisplintering insert is a removable plastic piece that sits in front of the blade and reduces the splintering of the material.
- Another quality feature is a blade guide. This is a disk that sits behind the blade and supports it, keeping it on a straight path and resisting deflection. It provides for a more accurate cut and helps prevent blade bending and breaking.
- Better models have orbital action for more aggressive cutting.
