If you’re looking for a capable and affordable chainsaw for your yard work, comparing the Worx WG505 vs WG509 is a smart place to start. Both are popular electric models that promise power without the fuss of gas. This guide will break down their differences so you can pick the perfect tool for your trees and projects.
These two saws from Worx share a lot of DNA, but key distinctions in power source and design make each one suited for different tasks. Whether you’re pruning apple trees or cutting firewood, understanding these details saves you time and money.
Worx WG505 vs WG509
At first glance, these chainsaws look similar. They both offer the convenience of electric operation, which means no fuel mixing, easier storage, and less noise. But the core difference is simple: the WG505 is a corded electric chainsaw, while the WG509 is a battery-powered cordless model. This fundamental choice affects everything from where you can use it to how long you can cut.
Let’s look at what each saw brings to your garden shed.
The Worx WG505 (Corded Electric)
This model plugs into a standard outlet. Its main advantage is consistent, unlimited power as long as you have an extension cord. You don’t have to worry about the battery dying halfway through a big log. It’s often the more powerful of the two in terms of raw motor output, making it good for longer, more demanding cuts if you have outlet access.
The Worx WG509 (Cordless Battery)
This saw runs on Worx’s 20V Power Share battery system. The big benefit here is total freedom of movement. There’s no cord to manage or get caught on branches. It’s ideal for quick jobs, pruning up in a tree, or working in areas far from an outlet. Your runtime depends on the battery capacity you use.
Head-to-Head Feature Comparison
To really see which saw fits your needs, we need to compare their specs side-by-side. Here’s a breakdown of the critical features.
Power Source and Performance
* WG505 (Corded): Draws power directly from an outlet. It typically features a 14.5-amp motor, delivering consistent torque for cutting through hardwoods and larger diameter logs. You can work all day without a power drop.
* WG509 (Cordless): Uses a 20V lithium-ion battery (usually sold separately). It provides excellent portability but with a limited run time. A 4Ah battery might give you 30-60 minutes of intermittent cutting. Power is good for most medium-duty tasks but can lag behind the corded version on the toughest jobs.
Bar Length and Cutting Capacity
Both saws usualy come with a 16-inch Oregon bar and chain. This is a great all-purpose size for homeowners. It lets you:
* Prune tree limbs safely from the ground.
* Cut fallen trees up to about 14-15 inches in diameter.
* Manage storm cleanup and process firewood logs.
The auto-tensioning system on both models is a huge plus. It keeps the chain at the right tightness with just the turn of a dial, which improves safety and cut quality.
Weight and Ergonomics
* WG505: Weighs approximately 10.8 lbs without the cord. The cord adds some drag and requires careful management to avoid cutting it accidentally.
* WG509: Weighs around 7.7 lbs without the battery. Adding a 4Ah battery brings it close to the corded weight. The lack of a cord makes it feel much more nimble and easier to handle overhead.
Both have a textured grip and are designed to reduce user fatigue, which is important for any extended cutting session.
Which Chainsaw Should You Choose?
Your decision ultimately comes down to your specific property and the type of work you plan to do most often.
Choose the Worx WG505 if:
* You have large, thick trees to cut or process a lot of firewood annually.
* Most of your work is within 100 feet of an electrical outlet.
* You value continuous power and don’t want to stop and recharge.
* Your projects often involve longer, uninterrupted cutting sessions.
* You want the lower upfront cost (since no battery/charger is needed).
Choose the Worx WG509 if:
* You need to move around a large property or work in multiple, distant spots.
* You frequently do light pruning, cleanup, or quick cuts.
* Safety is a top concern and you want to eliminate the trip hazard of a cord.
* You already own other Worx 20V Power Share tools, so you can share batteries.
* You need to make cuts above shoulder height or in awkward positions where a cord is a problem.
Practical User Tips for Both Saws
No matter which model you pick, following best practices will keep you safe and get the best results.
1. Always Wear Safety Gear.
This is non-negotiable. Your basic chainsaw kit should include:
* Safety glasses or a visor.
* Hearing protection (especially for the WG505).
* Heavy-duty work gloves.
* Chainsaw chaps or pants to protect your legs.
* Sturdy, non-slip boots.
2. Inspect Before Each Use.
Get in the habit of a quick 60-second check:
* Ensure the chain is sharp and properly tensioned.
* Check that the bar is secure and free of deep grooves.
* Look for any loose screws or parts.
* For the WG509, make sure the battery is fully charged.
3. Practice Proper Cutting Technique.
* Always cut at waist level or lower when possible.
* Let the saw do the work; don’t force it into the wood.
* Be mindful of kickback. Keep the nose of the bar away from other wood and the ground.
* Have a clear escape path in case the wood shifts.
4. Maintenance is Simple.
Both saws are low-maintenance compared to gas, but they still need care:
* Keep the air vents clean of sawdust.
* Regularly apply bar and chain oil (the reservoirs are easy to fill).
* Sharpen the chain often with a round file. A dull chain is dangerous and inefficient.
* Store the saw (and battery for WG509) in a dry, cool place.
Common Projects for Your Worx Chainsaw
Here’s how these tools can handle typical yard tasks:
Storm Cleanup: Both are excellent for clearing fallen branches. The cordless WG509 lets you navigate tangled debris more safely without a cord.
Firewood Preparation: For occasional firewood, both work. For serious cordwood processing, the unlimited runtime of the corded WG505 has a clear edge.
Tree Pruning and Limbing: The lighter, cordless WG509 is often the winner here. Its maneuverability is a big advantage when cutting branches at odd angles.
Building Garden Beds or Log Projects: Cutting logs for rustic edges or small construction is easy with either. Precision is easier with the quieter electric motors.
Frequently Asked Questions (FAQ)
Q: Can the Worx WG509 handle cutting down a large tree?
A: It can assist in taking down a large tree with proper technique, but it’s not ideal. For felling trees over 12-14 inches in diameter, a more powerful gas saw or professional help is recommended. The WG509 is best for limbing and sectioning once the tree is down.
Q: How long does the battery last on the WG509 chainsaw?
A: Runtime varies based on battery capacity (Ah) and the wood you’re cutting. A 4Ah battery typically provides 30-60 minutes of actual cutting time under normal use. Having a spare battery is a smart idea for bigger jobs.
Q: Is the Worx WG505 powerful enough for oak or maple?
A: Yes, the 14.5-amp motor in the WG505 has good torque for hardwoods like oak and maple. The key is using a sharp chain and feeding the saw at a steady, controlled pace. Don’t rush it.
Q: Are these chainsaws good for beginners?
A: Absolutely. Their electric start, lighter weight, reduced noise, and lower maintenance make them much less intimidating than gas models. The auto-tensioning system also removes a common point of frustration for new users. Always read the manual and practice safety first.
Q: Do I need to buy chain oil separately?
A: Yes, you need to supply standard bar and chain oil. The saws have a transparent reservoir so you can easily see when it needs a refill. Check it every time you use the saw.
Making the choice between the Worx WG505 and WG509 comes down to your balance of power and portability. If you have accessible outlets and demand continuous power for bigger jobs, the corded WG505 is a reliable workhorse. If you value complete freedom and mostly tackle lighter, quicker tasks around your property, the cordless WG509 is incredibly convenient.
Both are well-made tools that simplify yard care. By matching the saws strengths to your specific needs, you’ll get a partner that makes your outdoor projects smoother and safer for years to come. Remember to always prioritize safety gear and proper maintenance, no matter which model ends up in your hands.
