Jig Saws buying guide

Jigsaws

Jigsaws are very versatile, handy tools, combining many functions of a bandsaw and a scroll saw into one small, portable package.

Jigsaws come in corded and cordless models.

Cordless are more portable than their corded counterparts, but are more limited in the kinds of materials they can cut since tougher materials like metal will drain the battery faster. They come in 12-18 volt models.
Corded jig saws are tougher and more durable. They come in 3.5-6 amp models.

ConsumerSearch found that many reviewers liked the Bosch 1590 corded model with its Premium Control Blades, soft-start Constant Response circuitry, top handle and variable speed trigger. It also has a lock-on button and dial for speed-range selection with maximum 2800rpm.
Reviewers also liked the cordless 18V Bosch 52318 with the same soft-start Constant Response circuitry and variable speed trigger.
Both models also have some of the easiest blade changes available.

Variable Speeds allow you to adjust the blade speed depending on what you're cutting. The ability to differentiate also makes for cleaner, smoother cuts.

Should be trigger controlled, but some models have a lock-on dial for longer cuts.
Usually range from 500 to 3100 strokes per minute.

Orbital Action lets the blade move from side to side as well as up and down.

Jigsaws cut on the upward motion so splinters can be a problem, especially with plywood. Inserts can minimize splintering and keep wood splinters from flying back up into the tool and causing jams.
