Greenworks Impact Drivers
If your mower, blower or trimmer already runs on Greenworks 24V batteries, a Greenworks impact driver is the cheapest way to add one. Here is what the models offer and where they fall short.

A Greenworks impact driver makes most sense if you already own Greenworks 24V yard tools. The 24V brushless 1/4-inch drivers are rated at 1,950 in-lbs or, on the newer IS24L00, 2,650 in-lbs, and they share batteries with the mower and trimmer in your garage. For DIY fastening they are good value. Weaknesses: a thin range of building tools, a 2,800 RPM top speed that is slower than pro drivers, and patchy store availability.

Who should buy a Greenworks impact driver?
The best reason to buy a Greenworks impact driver is a Greenworks 24V battery you already own. If your string trimmer, leaf blower or mower runs on Greenworks 24V packs, a bare impact driver turns those batteries into a fastening tool for the cost of the tool alone. That is a better deal than buying into a second platform.
If you own no Greenworks tools, the case is weaker. Greenworks' strength is yard equipment, and its building-tool range is narrow compared with Ryobi, DeWalt or Milwaukee. This guide is based on Greenworks' published specs and warranty terms and on owner feedback. We did not test the tools.
A quick test for whether it fits you: count the Greenworks 24V batteries you already own. Two or more, and a bare driver is close to a free upgrade in battery terms. None, and you should compare the whole platform, not just the driver, because the batteries and charger are where most of the money goes.
Greenworks 24V impact driver models and specs
| Model | Motor | Max torque | Max speed | Impacts/min | Speeds |
|---|---|---|---|---|---|
| 24V 1/4 in. 2,650 in-lb brushless (IS24L00 bare; CKM407 kit) | Brushless | 2,650 in-lbs | 2,800 RPM | 3,500 IPM | 3 (100/200/300 Nm) |
| 24V 1/4 in. 1,950 in-lb brushless (bare and kits) | Brushless | 1,950 in-lbs | 2,800 RPM (one kit lists 3,400) | 3,500 or 3,800 IPM depending on listing | Check the current listing |
Greenworks' own pages disagree on some figures for the 1,950 in-lb driver, so check the specific SKU before buying. Torque is measured differently by every brand. Greenworks' 2,650 in-lb rating is the highest on this page, but do not assume it out-drives a Milwaukee rated at 2,000 in-lbs. Treat it as a strong DIY driver, not a pro tool that beats the leaders.
Notice the 2,800 RPM top speed. Pro 18V drivers reach 3,250 to 3,900 RPM. Lower top speed means slower driving on long screws, though it is rarely a problem for weekend projects.
The Greenworks model to buy
Greenworks 24V Brushless 1/4 in. Impact Driver, 2,650 in-lbs (IS24L00)
Best for: Greenworks 24V yard tool owners who want a capable driver for decks, fences and general DIY.
- Torque
- 2,650 in-lbs
- Speed
- up to 2,800 RPM
- Impacts
- 3,500 IPM
- Speeds
- 3
Three torque-limited speed settings help with small screws, and the higher torque rating gives headroom for lag screws with pilot holes. Buy it bare if you already own 24V batteries.
Strengths
- Uses the same 24V packs as Greenworks yard tools
- Three speed settings
- Brushless motor and 3-year limited warranty
Weaknesses
- 2,800 RPM top speed is slow next to pro drivers
- No self-tapping or assist modes
- Limited range of other building tools on 24V
Greenworks 24V Brushless 1/4 in. Impact Driver, 1,950 in-lbs
Best for: light DIY, furniture and shelving, or a cheap kit with batteries.
- Torque
- 1,950 in-lbs
- Speed
- up to 2,800 RPM
This driver is often sold in kits with two 2.0 Ah batteries and a bit set, which makes it a cheap way into the 24V system if you plan to add Greenworks yard tools later.
Strengths
- Kits often include two batteries
- Enough power for typical home projects
Weaknesses
- Spec listings are inconsistent between SKUs
- Slower and less refined than pro drivers
Reading Greenworks model codes and listings
Greenworks listings are confusing because the same driver appears under several codes. The model code (for example IS24L00) identifies the tool; kit codes (such as CKM407) identify a bundle; and many listings also show a separate SKU number. Retailers sometimes add the brand name POWERALL to 24V combo kits. Before you buy, confirm three things on the listing:
- Voltage: it must say 24V if you want to use your existing 24V packs.
- Torque class: 2,650 in-lbs or 1,950 in-lbs. The two drivers look similar in photos.
- What is in the box: "tool only" means no battery or charger. Kits vary between one 2.0 Ah pack, two 1.5 Ah packs and two 2.0 Ah packs.
Whichever model you choose, use impact-rated bits. Standard screwdriver bits snap under impact, and a worn bit causes most stripped screw heads. See our guide to impact driver bits for what to buy, and the impact driver battery guide for how capacity affects runtime and weight.
Battery sharing: the real reason to choose Greenworks 24V
Greenworks 24V packs power the drill, impact driver and a long list of yard tools: string trimmers, blowers, hedge trimmers, pruning saws and more. Many Greenworks 48V tools, such as mowers, take two 24V packs at once. That makes a stack of 24V batteries useful year-round.
- 2.0 Ah packs keep the impact driver light and are plenty for indoor work.
- 4.0 Ah and 5.0 Ah packs suit decking and long yard sessions, but add weight to a handheld driver.
- 24V packs do not fit Greenworks 40V, 60V or 80V tools.
Our Greenworks 24V battery guide lists current battery SKUs, chargers and how to avoid counterfeit packs.
Drill and impact driver combo kits
Greenworks sells the impact driver alongside its 24V brushless drill in two-tool kits with two 2.0 Ah batteries and a charger. For a homeowner who needs both tools and wants yard tools later, these kits are a sensible start. Compare them with combo kits from Ryobi, Skil and DeWalt in our guide to the best drill and impact driver combo kits before buying, since those platforms have deeper building-tool ranges.
Greenworks vs Ryobi and other yard-and-shop platforms
| Factor | Greenworks 24V | Ryobi ONE+ 18V | EGO 56V |
|---|---|---|---|
| Impact driver available (US) | Yes | Yes, several | Not listed on EGO's US site |
| Top rated torque | 2,650 in-lbs | 2,200 in-lbs | n/a |
| Building tool range | Basic | Very large | None |
| Yard tool range | Large | Large | Large |
| Warranty | 3-year limited (90 days commercial) | 3-year | Varies by product |
Torque ratings are brand-specific. Ryobi is the platform to beat if you want yard and building tools on one battery. Greenworks makes sense when you already own its yard tools. EGO owners face a different problem, covered in our EGO impact driver guide. For the full decision, read choosing a cordless tool platform.
Safety: wear eye protection while driving fasteners and hearing protection for long sessions. Impact drivers do not set final torque, so finish lug nuts and structural bolts with a torque wrench.
Verdict
A Greenworks impact driver is an easy recommendation if you already run Greenworks 24V yard tools: buy the 2,650 in-lb IS24L00 bare and use the packs you own. Starting from zero, it is a fair DIY choice, but Ryobi offers more tools on one battery, and pro brands offer faster, more refined drivers.
Frequently asked questions
Is Greenworks a good brand for power tools?
Greenworks is strongest in outdoor power equipment. Its 24V drills and impact drivers are reasonable DIY tools with brushless motors and a 3-year limited warranty. For daily trade use, brands with deeper tool ranges and service networks, like DeWalt or Milwaukee, are a better fit.
Do Greenworks 24V batteries work in 48V tools?
Yes, for Greenworks tools designed that way. Many Greenworks 48V mowers, trimmers and blowers take two 24V batteries at once. The impact driver itself takes one 24V pack. Check each tool's listing for how many packs it needs.
Can I use a Greenworks 40V battery on the 24V impact driver?
No. Greenworks runs several separate platforms (24V, 40V, 60V and 80V), and the packs do not interchange. Only 24V batteries fit the 24V drill and impact driver.
Is a Greenworks impact driver brushless?
The current 24V 1/4-inch impact drivers sold on Greenworks' site are brushless. Older or bundled models may differ, so confirm the word brushless and the model code on the listing before you buy.
