Worx Wg505 Vs Wg509

If you’re looking at cordless garden saws, you’ve probably come across the Worx WG505 and WG509. This Worx WG505 vs WG509 comparison will help you pick the right tool for your yard work. Both are part of Worx’s Nitro line, known for good power in a lightweight package. But they have key differences that make each one better for specific jobs around your garden.

At first glance, these two tools look very similar. They both use Worx’s 20V Power Share batteries, so if you already own other Worx tools, you’re set. They’re designed for pruning, cutting firewood, and general yard cleanup. However, the choice between them comes down to bar length, power delivery, and the type of cutting you do most often.

Key Specifications Side-by-Side

Let’s break down the numbers first. Here’s a quick overview of how they stack up:

Model: WG505 (Nitro) | WG509 (Nitro)
Power Source: 20V Battery | 20V Battery
Bar Length: 10 inches | 12 inches
Chain Speed: Up to 17.1 ft/s | Up to 20 ft/s
Weight (Tool Only): ~6.6 lbs | ~7.1 lbs
Auto-Tensioning: Yes | Yes
Oiler: Automatic | Automatic

Bar Length and Cutting Capacity

The most obvious difference is the bar. The WG505 has a 10-inch bar, while the WG509 sports a 12-inch bar. This means the WG509 can handle thicker branches and logs in a single pass. For most pruning jobs on trees and large shrubs, the 10-inch bar is perfectly adequate. But if you’re processing firewood or have larger trees to manage, the extra 2 inches on the WG509 provides valuable extra reach and capacity. You’ll find you can tackle a wider range of projects without straining the saw.

Power and Chain Performance

Both are called “Nitro” for a reason. They use a high-efficiency brushless motor. The WG509, however, has a slight edge in chain speed. It moves the chain at up to 20 feet per second, compared to the WG505’s 17.1 ft/s. In practice, this means the WG509 might feel a bit quicker through dense wood. It’s a subtle difference for light work, but noticeable on tougher cuts. The motors on both are designed to conserve battery life, which is a huge plus when you’re away from an outlet.

Battery Life and Practical Use

Since they use the same batteries, runtime depends on the work. The WG509’s longer bar and higher speed can draw more power on big jobs. For a typical user doing mixed pruning, you can expect a good 30-45 minutes of intermittent cutting on a 4Ah battery. It’s always smart to have a spare battery charged and ready. The ergonomics are excellent on both models, with a well-balanced design that reduces arm fatigue during extended use.

Who Should Choose the Worx WG505?

The WG505 is a fantastic all-purpose pruning saw. It’s ideal for:

Homeowners with mature shrubs and small to medium trees.
General yard cleanup after storms.
Cutting branches up to about 8-9 inches thick comfortably.
Gardeners who value a lighter tool for overhead work.

Its slightly lighter weight makes it easier to handle for detailed pruning work. If your projects rarely involve wood thicker than a dinner plate, the WG505 is likely all the saw you need. It’s also often a bit more affordable, which is a nice bonus.

Who Should Choose the Worx WG509?

The WG509 steps up for more demanding tasks. You’ll benefit from it if:

You regularly cut firewood or fell small trees.
You have many large-diameter trees on your property.
You want the extra speed for faster cutting on big jobs.
You prefer the maximum capacity in a compact, cordless form.

The extra bar length means you can confidently approach a 12-inch log. For serious yard management, the WG509’s versatility is hard to beat. It bridges the gap between a pruning saw and a larger chainsaw very effectively.

Shared Features You’ll Appreciate

Both models come with Worx’s helpful feature set. These make maintenance and operation much simpler.

Auto-Tension: The chain automatically tightens as needed. You never need a tool to adjust it, which saves so much time and hassle.
Automatic Oiler: It lubricates the chain while you cut. Just remember to keep the oil reservoir filled before each use.
Tool-Free Chain Cover: You can remove the cover to clean or replace the chain without fumbling for a wrench.
Safety Switch: A built-in switch prevents accidental starts, which is crucial for a safe gardening experience.

Making Your Final Decision

Choosing between these two excellent tools isn’t about which is “better,” but which is better for you. Consider these steps:

Assess Your Typical Projects: Walk your property. What’s the thickest material you need to cut regularly?
Consider Your Strength & Comfort: If you have concerns about handling a heavier tool, the WG505’s lighter feel is a real advantage.
Check Your Budget: Often, the longer-bar model costs a little more. Decide if the extra capacity is worth the investment for your needs.
Think About Future Needs: Are you planning to plant more trees? Maybe you’ll take on more wood-cutting projects. Sometimes, buying a little more saw than you currently need is a smart move.

Both saws are built to last and will handle far more than most homeowners throw at them. You really can’t go wrong with either choice from the Worx Nitro line.

Care and Maintenance Tips

To keep your saw running smoothly for years, follow these simple steps:

Always clean debris from the chain cover and bar groove after use.
Use only high-quality bar and chain oil. Check the level every time you pick up the saw.
Store the battery separately in a cool, dry place when not in use for long periods.
Sharpen the chain regularly. A dull chain makes the motor work harder and drains the battery faster.
Inspect the chain for damage or excessive wear before each use, its a simple safety must.

Frequently Asked Questions (FAQ)

Can the WG505 and WG509 use the same chains?

No, they cannot. Because the bars are different lengths (10″ vs 12″), the drive links on the chain will be different. You must purchase the correct chain size for your specific model. Always refer to your manual for the right part number.

Are these saws powerful enough for cutting down a tree?

They are capable of felling small trees, especially the WG509 with its 12-inch bar. For anything larger than about 10 inches in diameter or for trees near structures, it’s safer and more efficient to hire a professional. These are best for pruning and cutting already fallen wood.

What’s the main advantage of the Nitro brushless motor?

Brushless motors are more efficient, which translates to longer battery life and more power for the same size tool. They also have fewer wearing parts, so the motor itself tends to last longer than traditional brushed motors. You get more work done per charge.

Do I need to wear special safety gear?

Absolutely. Always wear safety glasses, sturdy gloves, long pants, and closed-toe shoes when operating any chainsaw. Hearing protection is also recommended. Never operate the saw above shoulder height or on a ladder. Safety should always be your first priority, no matter how small the job seems.

Is the auto-tension system reliable?

Yes, Worx’s auto-tension system is generally very reliable. It keeps the chain at the optimal tightness, which improves cutting performance and safety. It eliminates a common maintenance step that many people forget to do, making the whole tool much more user-friendly for casual gardeners.

In the end, the Worx WG505 is your go-to for precision pruning and lighter tasks, while the WG509 offers extended reach and power for bigger projects. By matching the tool to your garden’s specific demands, you’ll get a partner that makes yard work quicker and much more satisfying. Just remember to keep that chain sharp and the battery charged!
