Best Jigsaw for Decking

The Bosch GST 18V-125 SC features a brushless motor that maintains consistent cutting speed even when ripping through 2-inch pressure-treated deck boards. Its four orbital action settings allow you to dial in aggressive cuts for rough framing or fine, clean cuts for fascia and trim work. Aggregated owner reviews from major retailers highlight the tool's smooth operation and low vibration, which reduces fatigue during long decking sessions.

The integrated dust extraction system directs sawdust away from the cut line, keeping your layout marks visible. The LED light illuminates the cut area, which is helpful when working under a deck or in dim light. While the tool itself is premium, the lack of a kit case means you will need to budget for storage separately.

The DeWalt DCS335B offers a variable speed trigger that gives you full control over cut speed, which is critical when navigating curves in deck boards or cutting around posts. The keyless blade change system allows for fast swaps between coarse and fine blades. Owner reviews consistently praise the tool's ergonomic grip and balanced weight distribution, making it comfortable for extended use.

With a 1-inch stroke length, it is slightly less aggressive on thick timber compared to the Bosch, but it still handles standard 5/4 decking and 2x6 joists without bogging down. The LED light is positioned to minimize shadowing on the cut line. Users on the DeWalt 20V system will appreciate the compatibility with existing batteries.

The Makita 4329M is a straightforward, corded jigsaw that delivers consistent power for cutting deck boards without the need to manage battery charge. Its 6.5-amp motor provides enough torque for pressure-treated lumber, and the two orbital settings allow you to switch between fast cuts and cleaner finishes. Aggregated owner reviews note that this model is built to last, with many users reporting years of reliable service.

At 4.6 pounds, it is one of the lightest options, reducing fatigue during long cutting sessions. The lack of a dust blower and LED light means you will need to work in good lighting and manage sawdust manually. However, for the price, it offers excellent value for DIY deck builders who do not need advanced features.

The Milwaukee 2736-20 features a 1-1/4 inch stroke length and a maximum speed of 3,500 SPM, making it the most aggressive jigsaw for cutting through thick decking and joists quickly. The brushless motor delivers consistent power, and the four orbital settings allow you to adjust the cut for different materials. Owner reviews highlight its ability to power through knots and dense hardwood decking without slowing down.

The tool is heavier than most at 6.2 pounds, which can lead to fatigue during extended use. It also requires an M18 battery, and the price reflects the premium build quality. For professional deck builders who need maximum cutting speed and durability, this is a strong contender.

The Ryobi P5231 is the most affordable cordless jigsaw in this roundup, making it an excellent entry point for DIY deck builders. It features a 3/4-inch stroke length and 3,000 SPM, which is sufficient for cutting standard 5/4 deck boards and thin plywood. The tool-free blade change system is convenient, and the two orbital settings provide basic versatility. Owner reviews on retailer sites note that it works well for occasional use and small deck projects.

With only a 3/4-inch stroke, it struggles with thicker joists and dense hardwood decking. Users also report higher vibration levels compared to premium models, which can lead to fatigue. However, for the price and the extensive Ryobi ONE+ battery ecosystem, it offers solid value for budget-conscious homeowners.
