Greenworks 24V Brushless Cordless Impact Driver Review
If you’ve been scrolling through tool reviews trying to figure out if the Greenworks 24V Brushless Cordless Impact Driver is actually worth it, you’re definitely not alone. Maybe you’ve seen it pop up as a cheaper alternative to big brands, or maybe you already own a Greenworks lawn mower or blower and you’re wondering if their power tools are just as good.
Here’s the usual problem most people run into: you either spend a lot on a pro-level tool you’ll rarely push to its limits, or you go cheap and end up with something that struggles with basic jobs. The Greenworks 24V sits right in the middle of that gap — a brushless motor, decent power, and often sold as a kit with a battery, all at a more affordable price than brands like Milwaukee or DeWalt.
But does it actually perform well? We tested it ourselves to find out. From driving screws and lag bolts to checking noise levels and durability, we put it through real-world use so you don’t have to guess. And if you’re still comparing options, we also put together a full impact driver comparison where we tested six popular models side by side.
Quick Verdict
✅ Best for: Eco-conscious homeowners, existing Greenworks 24V users, first-time kit buyers, and budget-minded DIYers who want brushless motor performance with batteries included — without paying Milwaukee or DeWalt prices.
❌ Not ideal for: Full-time professional contractors, users who need multi-speed control, anyone already invested in a larger battery platform like Ryobi ONE+, Milwaukee M18, or DeWalt 20V MAX.
💬 Bottom Line: The Greenworks 24V Brushless Impact Driver delivers where it counts — strong torque, a brushless motor, and a complete ready-to-use kit at a price that undercuts most of the competition. The smaller ecosystem is its only real weakness, but for buyers focused on the tool itself rather than long-term platform growth, it’s one of the best value picks in its class.

How We Tested
To assess how effective Greenworks 24V Brushless Cordless Impact Driver is, we conducted several hands-on tests designed to simulate real-world jobsite conditions. We focused on important areas such as speed, power, noise output, and durability.
Screw Driving Speed Test – We measured how quickly the impact driver could drive multiple screws into wood to evaluate its efficiency during repetitive tasks.
Lag Bolt Power Test – Large lag bolts were driven into dense material to test the tool’s torque and determine how well it performs under heavy-duty applications.
Noise Level Test – We observed the sound produced by the impact driver during both standard and demanding use to get a better idea of its operating noise levels.
Durability Test – The tool was dropped from typical working heights onto hard floor surface to examine its toughness and see how well it withstands jobsite impacts.
Performance Test
Screw Driving Speed Test
To evaluate the tool’s screw driving performance, we used #16 x 4-inch wood screws and drove them into a 4×6 wood block to replicate a common fastening application.
During the test, the Greenworks impact driver maintained a steady and consistent driving speed. It was able to drive the screw completely flush into the wood in approximately 11 seconds, showing solid efficiency for routine fastening tasks.
Lag Bolt Test (Power Test)
Next, we tested the impact driver’s power by driving ½-inch x 5-inch lag bolts into the same wood material to simulate a more demanding fastening task.
The tool started strong with good initial speed, but its performance slowed down around the 30-second mark before eventually stopping. The lag bolt was not fully driven flush into the wood which indicates that the tool may struggle with heavier-duty applications.
Noise Level Test
Since Greenworks brushless cordless impact drivers are known for being noisy during operation, we measured the tool’s sound levels using a sound meter positioned about 2 feet away.
When lightly pressing the trigger, the impact driver produced around 80 decibels. During actual screw driving, vibration from the tool was strong enough to shake the sound meter and move the tape measure nearby. Under load, the noise level increased to approximately 93 decibels, making the tool noticeably loud and vibration-heavy during use.
Durability Test (Drop Test)
Durability plays a major role when choosing an impact driver, so we performed a drop test to evaluate how well the tool could withstand jobsite impacts and whether it would continue functioning afterward.
The impact driver handled the drop without any noticeable issues. After the test, it still powered on normally and remained fully operational.
Greenworks 24V Brushless Cordless Impact Driver Pros and Cons
✅ Pros
Impressive Torque for the Price
At the heart of the Greenworks ISG402 is a highly efficient brushless motor that delivers 1,950 in-lbs of maximum torque and up to 2,600 RPM, enabling the driver to handle demanding different driving applications with ease.
Exceptionally Compact & Lightweight
Measuring just 5 inches long. Its slim build makes it ideal for small or tight spaces where larger tools can’t fit easily. At only 2 pounds as a bare tool, it’s also one of the lightest options available, helping reduce fatigue during extended use.
Brushless Motor Efficiency
The 24V lithium-ion battery offers reliable, fade-free power and up to 35% longer runtime compared to standard batteries, helping users complete projects faster without frequent recharging.
Great Kit Value — Batteries Included
It comes with a pair of 2.0Ah Greenworks batteries, a charger, and a soft carrying case — retailing for $119.99 from Amazon — making it an excellent value compared to bare-tool competitors at a similar price.
Solid Build Quality
The tool feels very robust in a well-built sort of way, with a rubber over-molded grip that offers substantial grip even without gloves or on particularly hot days.
Eco-Friendly Battery Platform
Running on a 24V system has real advantages — technically 24V max, the tool runs at 21.6V nominally thanks to a 6-cell battery system, storing more energy compared to standard 18V/20V max tools.
Reliable 3-Year Warranty
Greenworks backs both the tool and batteries with a 3-year limited warranty, adding solid peace of mind for buyers.
❌ Cons
Single-Speed Limitation
The downside is that the ISG402 is a single-speed model. If three speeds is a must, you’d need to step up to Greenworks’ more powerful ISD401 model.
Smaller Ecosystem
Greenworks’ 24V platform is compatible with a wide range of their own products, but the ecosystem is considerably smaller than platforms like Ryobi ONE+ or Milwaukee M18, which limits your long-term tool expansion options.
Not Built for Heavy Professional Use
Users who require ultra-lightweight tools for extended overhead use may find it slightly heavy, and those needing torque exceeding 2,000 in-lbs for very heavy-duty industrial work should look elsewhere.
Included Bits Are Low Quality
Some users reported poor build quality with the included bits — one noting the very first bit snapped almost immediately — suggesting you’ll want to invest in a separate quality bit set.
Less Brand Recognition
While Greenworks is well established in outdoor power equipment, it carries less brand authority in the cordless hand tool space compared to Milwaukee, DeWalt, or even Ryobi — which may give pause to buyers looking for long-term parts and service support.

vs. Milwaukee M18 Compact Brushless
Milwaukee carries a stronger brand reputation, a best-in-class 5-year warranty, and is the lightest tool here at 1.7 lbs. But it starts at $99–$149 with no battery included. The Greenworks ships as a complete kit with two batteries at a lower price — and actually delivers more torque (2,650 vs. 1,700 in-lbs).
vs. DeWalt 20V MAX XR
The closest match in the group. Both are brushless with serious torque, but DeWalt costs $129–$199 with no battery and tops out at a higher RPM. Greenworks delivers comparable torque, ships with two batteries, and costs significantly less. DeWalt’s larger 200+ tool ecosystem gives it the long-term edge.
vs. Ryobi 18V ONE+
Ryobi’s 300+ tool ecosystem is the largest here, making it the smarter pick for long-term collection building. But for first-time buyers starting fresh, Greenworks has the edge — brushless motor, higher torque, and batteries included at a similar price.
vs. Galax Pro 20V
No contest. The Galax Pro delivers less than half the torque (882 in-lbs), carries only a 1-year warranty, and offers no real upgrade path. The Greenworks is a dramatically better investment at a modest price difference.
vs. Black+Decker 20V
Black+Decker is the heaviest tool here at 3.6 lbs, produces only 1,375 in-lbs of torque, runs a brushed motor, and has no LED light — all at a similar price to the Greenworks. Its brushed motor also means faster wear over time, more heat buildup, and shorter overall lifespan compared to the Greenworks’ brushless design. The upgrade is obvious.
Who Will Benefit Most from The Greenworks 24V Impact Driver?
✅ Who Should Use It
Existing Greenworks Ecosystem Users
If you already own Greenworks 24V outdoor power equipment (lawn mowers, leaf blowers, trimmers) adding this impact driver is a natural and cost-effective move. Your existing batteries work across the entire 24V lineup, so you’re not starting from scratch.
Eco-Conscious DIYers
Greenworks has built its reputation around cleaner, greener power solutions. If sustainability matters to your buying decisions, this is one of the few cordless impact driver brands that genuinely aligns with that value — without sacrificing real performance.
Homeowners & Casual DIYers
With 1,950 in-lbs of torque and a brushless motor packed into a 5-inch compact frame, it handles the full range of everyday home improvements — furniture assembly, deck screwing, fence repairs, and cabinet installations — with ease and comfort.
Users Who Want Batteries Included
Unlike many competitors at this price point that sell bare tools only, the Greenworks kit ships with two 2.0Ah batteries, a charger, and a carrying bag. For first-time buyers with no existing battery platform, that’s immediate out-of-the-box value.
Those Working in Tight Spaces
At just 5 inches long and 2 pounds bare, it’s one of the most compact and lightweight options in its class. Anyone doing overhead work, crawlspace repairs, or cabinet installations will appreciate how easy it is to maneuver.
Budget-Minded Buyers Who Don’t Want to Sacrifice Motor Quality
The brushless motor sets it apart from similarly priced brushed competitors. For buyers who understand the long-term efficiency and durability benefits of brushless technology but don’t want to pay Milwaukee or DeWalt prices, this hits a genuine sweet spot.
❌ Who Should Look Elsewhere
Users Who Need Multi-Speed Control
The standard ISG402 is a single-speed model. If you regularly work across a variety of materials and need precise speed switching, you’ll either need to step up to the Greenworks ISD401 or consider a different brand altogether.
Full-Time Professional Contractors
Like most mid-tier tools, the Greenworks 24V isn’t built to withstand the punishment of daily heavy job site use. Professionals who depend on their tools for their livelihood are better served by Milwaukee M18 FUEL or DeWalt XR.
Those Building a Large Tool Collection
With around 150 compatible 24V tools, the Greenworks platform is significantly smaller than Ryobi ONE+ (300+), Milwaukee M18 (250+), or DeWalt 20V MAX (200+). If long-term ecosystem growth matters to you, this may limit your options.
Users Already Invested in Another Battery Platform
If you’re already running multiple products like Milwaukee, DeWalt, Ryobi, or Makita batteries, switching to Greenworks’ 24V system just for an impact driver doesn’t make financial sense. Stick with your existing platform.
Frequently Asked Questions
1. Are the Greenworks 24V batteries compatible with other Greenworks tools?
Yes, absolutely. The 24V batteries included in the kit are compatible with 200+ Greenworks 24V tools. You can use these batteries with other Greenworks 24V tools like leaf blowers, string trimmers, lawn mowers, chainsaws, and more.
2. Can the Greenworks 24V Impact Driver be used to drill into concrete?
While the unit can be used as a hammer drill, it is only suitable for light-duty applications such as brick. For drilling into cement walls or concrete, you would need a dedicated hammer drill.
3. What drill bits are compatible with the Greenworks 24V Impact Driver?
Since bits are universal, any drill bits specifically designed for use with a 1/4-inch hex drive will work — they don’t have to be Greenworks-branded.
4. Can it remove lug nuts from tires?
Yes, you can remove lug nuts with the impact driver, but it is best to first use a breaker bar to loosen them and then use the impact driver to spin them off quickly.
5. Should I remove the battery when the tool is not in use?
Unless the trigger is activated, the battery should have no effect on the tool. It is good practice to keep the trigger in a locked position when not in use, especially when in transit.
6. Does the Greenworks 24V Impact Driver have an LED work light?
Yes — it features a built-in LED working light with a delay illumination function that lights up the workspace, making it easier to work in dark or confined spaces.
7. Can the USB-C batteries be used as a power bank for phones or devices?
Yes — the 2.0Ah 24V USB-C batteries double as a power bank, capable of charging phones and other devices while you work.
8. Is the Greenworks 24V Impact Driver good for professional use?
It depends on the application. The brushless motor and strong torque output make it capable enough for light-to-medium professional tasks like carpentry, electrical work, and home renovation. However, for sustained heavy-duty daily job site use, professional-grade tools from Milwaukee or DeWalt remain the more reliable choice.
Final Verdict: Is the Greenworks 24V Brushless Cordless Impact Driver Worth It?
The Greenworks 24V Brushless Impact Driver genuinely surprises in a market crowded with overpriced premium tools and underwhelming budget options. It delivers the highest torque in its comparison group at up to 2,650 in-lbs, runs an efficient brushless motor, and ships as a complete kit with two batteries, a charger, and a carrying bag — all at a price that leaves Milwaukee and DeWalt looking hard to justify for everyday home use.
Our hands-on testing backed that up. It drove screws flush in 11 seconds, handled lag bolts with solid initial power, survived a drop test without skipping a beat, and felt genuinely comfortable in hand thanks to its compact 5-inch frame and lightweight 2-pound build.
Where it shows its limits is under sustained heavy-duty use. The lag bolt test revealed that it slows down before fully seating larger fasteners, and the single-speed design means you’re relying on trigger control rather than dedicated speed modes for precision work. Add in a smaller 24V ecosystem and less brand recognition in the hand tool space, and it’s clear this isn’t the tool for professionals who push their equipment to the limit every day.
But for everyone else — the homeowner tackling weekend projects, the eco-conscious DIYer already in the Greenworks world, or the first-time buyer who wants brushless performance without the premium price — the Greenworks 24V punches well above its weight.
