Dewalt Brushless SDS+ Hammer Kit, 18V, 4Ah Battery Pack

The brushless motor is in the hammer tool (for example, the DCH133M1EXP-GB). The 4Ah battery pack powers the tool. Together they provide efficient performance, but the motor itself is a feature of the tool, not the battery.

The three modes typically cover rotation (drilling), rotation with hammering (drill + hammer), and hammering only (chiseling). The 4Ah battery provides consistent power across all modes, while the depth stop helps you preset drilling depth for repeatable results.

Key features include a dust exhaust adaptor for dust extraction, a non-slip rubber handle for comfortable grip and control, a 3‑mode control switch for versatile operation, and a depth-stop for consistent drilling depth.

Yes. The 18V XR 4Ah battery is designed to be compatible with DeWalt 18V XR tools across the lineup, so it should work with other DeWalt 18V XR cordless tools you own.

With a 4Ah capacity, you can expect extended run time compared with lower-capacity packs. Actual runtimes depend on the task, tool model, and operating conditions, but the 4Ah pack is designed for fade-free performance until the charge declines.

This 4Ah pack offers a solid balance of runtime and compatibility within the 18V XR ecosystem. If you need longer runtime, you might compare with a 5Ah option. For reference, similar 4Ah and 5Ah DeWalt XR batteries are also listed on Fepy, such as the DCB184 (4Ah) and DCB205 (5Ah).

Slide the battery onto the tool’s handle until it clicks into place, ensuring the battery is fully seated with the contacts aligned. To remove, press the release latch and pull the battery straight off.

Charge the battery with an appropriate DeWalt charger in a cool, dry environment. Avoid exposing the battery to extreme temperatures, water, or flames. When storing for long periods, it’s best to store with a moderate state of charge and keep the terminals clean and dry.

Wear eye protection, hearing protection, and a dust mask or respirator. Use the dust extraction adaptor if available, and follow standard workshop safety practices to protect against debris and noise.

Ideal for masonry drilling, drilling with hammer action, and chiseling tasks. It’s well-suited for professional trades, renovations, and DIY projects that require a robust, cordless SDS+ hammer with reliable power delivery.

DCB184 is a 4Ah 18V XR battery and is a direct, lower-capacity option with similar runtime to this pack. DCB205 is a 5Ah option offering longer runtime. If you want equivalent capacity with a slightly lighter pack, check DCB184; for extended runtime, consider DCB205.
