Overview

Cordless on a 20 volt battery, the SKIL JS820302 weighs 4.9 pounds and handles up to 8 inches of cutting capacity, rated 4.7 across 410 reviews.

The JS prefix in the model number lines up with Skil's jig saw naming convention, and the light 4.9 pound weight fits a handheld tool meant for curved or detail cuts rather than a stationary saw. Running on the 20 volt battery platform keeps it cordless, trading the reach of a corded shop saw for portability at the job site.

Who it's for

DIYers or tradespeople who want a cordless, lightweight saw for detail or curved cutting work up to 8 inches of capacity. Not the choice for heavy stationary cutting, where a corded saw with more capacity and sustained power fits better.

Performance notes

At 4.9 pounds, this saw stays light enough for extended one-handed use, which suits the detail and curved cutting typical of a jig saw more than straight ripping. The 20 volt battery platform keeps it cordless at the cost of the sustained power a corded saw offers, and the 8 inch capacity covers most handheld cutting tasks.
