10 Best Cordless Jack Hammers 2026 in the United States

The DEWALT DCH966Z2 is a powerful cordless jack hammer designed for heavy-duty concrete work. It runs on a strong 60V battery system, delivering an impressive 41 joules of impact energy, which means it can chip through concrete quickly and efficiently. It includes two lithium-ion batteries, offering decent runtime. One notable feature is its brushless motor, which generally means better durability and efficiency.

The tool weighs 64 pounds, which is quite heavy for a cordless jack hammer, so it might be challenging to handle for extended periods, especially if you’re working in tight spaces or overhead. However, it includes ergonomic design elements and vibration control to help reduce user fatigue. The redesigned 1-1/8" hex tool holder allows fast accessory changes, adding convenience on the job.

It also features smart tech like Wireless Tool Control, letting you connect to a compatible DEWALT dust extractor (sold separately) for cleaner work areas, and is tag-ready for tracking via the DEWALT Tool Connect app, which is handy for job sites. The tool comes with batteries and a charger but lacks a dust extractor, which must be purchased separately. It is particularly suited for professional users or serious DIYers who prioritize power and smart functions over lightweight convenience.

The DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) is a versatile and efficient tool designed for various drilling applications.

The cordless nature, combined with a lightweight design, makes it highly portable and easy to handle for tasks such as rod hanging, seismic attachments, and cable tray mounting.

One of its standout features is the SHOCKS ACTIVE VIBRATION CONTROL System, which significantly reduces vibration, enhancing user comfort during prolonged use. The brushless motor ensures efficient performance and longer runtime, which is ideal for demanding jobs. The tool offers three application modes—drill, hammer drill, and chip—adding to its versatility. However, it is important to note that the product comes as a bare tool, meaning the battery and charger are not included.

Additionally, at 6.4 pounds, it is relatively lightweight, making it easier to manage during extended use.

Additionally, the AUTOSTOP control feature provides safety by sensing bind-ups, reducing the risk of injury or damage during use. Weighing in at 7.8 pounds, it strikes a balance between being lightweight and durable, making it easier to handle for extended periods without causing too much strain. The ergonomics and vibration control also contribute to user comfort.

One potential drawback is that the battery and charger are not included, which means additional purchases are necessary to get started. Additionally, while the product is part of the M18 system with over 200 compatible solutions, users who are not already invested in this ecosystem might need to consider compatibility with their existing tools and accessories. The maximum rotational speed of 1330 RPM and a decent drilling capacity for both metal and wood broaden its usability. For those who already use Milwaukee tools, this model’s integration within the system is a considerable advantage.
