The DeWalt 20-Volt MAX 12-inch brushless chainsaw has become a popular choice for homeowners and those already invested in the DeWalt battery ecosystem. This review synthesizes user experiences with the original DCCS620 model and the updated DCCS621 version to help you decide which model fits your needs.
Introduction to the DeWalt 20V Platform
The DeWalt 12-inch chainsaw is designed as a compact, battery-powered alternative to gas saws. It eliminates the need for mixing gas and oil, manages exhaust fumes, and significantly reduces motor noise. Users find it much less intimidating than gas-powered counterparts, making it an excellent "entry-level" saw for building cutting confidence.
Key Features and Specifications
Both models share a core set of features designed for light to medium duty work around the yard:
- Brushless Motor: Provides efficient power and durability.
- 12-Inch Oregon Bar and Chain: Features a low-kickback design for improved safety.
- Portability: The bare tool weighs approximately nine pounds with a 5 Ah battery attached.
- Safety Mechanisms: Includes a chain brake that stops the chain quickly in the event of kickback and a lock-off lever to prevent accidental starts.
Model Comparison: DCCS620 vs. DCCS621
While the saws look similar, DeWalt made several design changes in the newer DCCS621 model to address common user feedback.
Toolless vs. Tool-Required Maintenance
The original DCCS620 features a completely toolless design for bar and chain adjustments, using a large locking knob and a tensioning wheel. However, the newer DCCS621 moves to a tool-required design where a wrench (stored in the base) is used to loosen the bar nut. Users have found that the tool-based system on the 621 is actually faster to operate than the older toolless version.
Oil Reservoir and Leaking
One of the primary complaints regarding the DCCS620 is its oil reservoir. The fill gauge is oddly positioned because the saw must be filled on its side, making the gauge difficult to use during the process. Furthermore, the DCCS620 is known to leak bar oil significantly during storage.
The DCCS621 introduces a raised, traditional screw-on cap that is easier to keep clean from sawdust. While all chainsaws may drip slightly after use, the 621's cap design appears to provide a better seal and reduces the likelihood of leaks from the reservoir itself.
Performance and Efficiency
Testing indicates that the DCCS621 is the superior performer in several categories:
- Efficiency: DeWalt claims the 621 can achieve 100 cuts on 4x4 lumber compared to 90 cuts for the 620 when using a 5 Ah battery.
- Cutting Experience: Users report the DCCS621 is quieter, smoother, and exhibits much less "chatter" or hopping during cuts than the older model.
- Speed: Despite similar official chain speed specs, the DCCS621 has been shown to cut faster in real-world testing and under tachometer observation.
Pros and Cons
Pros
- Ease of Use: Extremely simple to start and operate compared to gas saws.
- Low Maintenance: Toolless or quick-tool access to the sprocket and bar makes cleaning straightforward.
- Improved Design (DCCS621): The newer model features a more open sprocket cover that captures less sawdust and is easier to clean.
- Comfort: The compact size and weight make it comfortable for extended use on small logs.
Cons
- Battery Hungry: High-capacity batteries are essential. A 5 Ah battery is the recommended minimum for productive work.
- Oil Management: The DCCS620 specifically is prone to leaking oil while stored and has a poorly positioned fill gauge.
- Non-Clicking Knob (DCCS620): Some users reported that the bar adjust locking knob on the 620 does not "click" as the manual describes, though DeWalt confirms it remains secure if tightened properly.
Target Audience
This chainsaw is ideal for:
- Homeowners and Weekend Warriors: Perfect for cutting up small logs, clearing limbs, or processing firewood.
- Existing DeWalt Users: Those already owning 20V MAX batteries can save money by purchasing the bare tool.
- Beginners: Its lightweight nature and simple operation make it a great "rookie" saw for those intimidated by larger equipment.
Final Verdict
If you are choosing between the two, the DCCS621 is the clear winner. Its improvements in battery efficiency, cutting speed, and oil reservoir design make it worth the investment over the older model. If you currently own the DCCS620, it remains a capable "workpony" for small tasks, but be prepared to store it on a rag to catch oil leaks. For anyone seeking a portable, low-maintenance saw for light timber work, this 20V platform provides a solid
