If you’re tired of hand-pumping grease on every bushing and bearing, a cordless grease gun that works with your existing DeWalt batteries is a big improvement. I’ve spent hours greasing tractors, skid steers, and heavy equipment to find which one actually delivers the pressure and runtime you need without the hassle.
I picked these 5 based on three hard criteria: they all run on DeWalt 20V batteries, they push at least 10,000 PSI, and they’ve got enough real-world reviews to prove they work. I didn’t include anything that felt flimsy or had a ton of complaints about leaking or air locks.

How I Selected These Products
I only looked at cordless grease guns that hit at least 10,000 PSI and run on DeWalt 20V batteries. Anything less just won’t cut it for farm equipment or heavy machinery, and I wanted options you could actually use with batteries you might already own.
Value mattered more than just the lowest price. I ranked guns higher if they offered variable speed triggers, longer hoses, or dual-grip designs that make real-world greasing faster and less frustrating. A cheap gun that fights you isn’t a deal.
User feedback was the final filter. I read through hundreds of reviews to check for common complaints like leaking couplers, air lock issues, or poor build quality. Products that held up under real abuse got the nod over flashy specs that don’t deliver.
Best Overall
DEWALT Grease Gun 20V MAX
10,000 PSI | 42″ Hose | Variable Speed Triggers | Tool Only | 4.8 Stars (6,235 Reviews)
- DEWALT cordless grease gun can power through clogged grease fittings with a...

- The battery operated grease gun can control grease flow with the variable...
This is the grease gun that set the standard for cordless greasing, and after using it on everything from tractor hitches to skid steer pins, I get why. The 10,000 PSI delivers consistent flow even on stubborn zerks, and the variable speed trigger gives you real control so you don’t blast grease everywhere. With a 42-inch hose, I can reach fittings tucked behind frames without contorting my arm.
This gun is best for anyone who already owns DeWalt 20V batteries and needs a reliable, no-nonsense tool for daily farm or shop work. The only catch is it’s tool-only, so if you don’t have a battery and charger, you’ll need to factor that in or grab the kit version instead.
✅ Pros
- Variable speed trigger gives precise control for different fittings
- 42-inch hose reaches tight spots easily
- Over 6,200 reviews with a 4.8-star average speaks for itself
- Runs on all DeWalt 20V MAX batteries you probably already own
❌ Cons
- Tool only — no battery or charger included
- Heavier than some budget alternatives at nearly 10 pounds with battery
Best Kit
DEWALT Grease Gun 20V MAX

- Long Runtime - Stay productive with the ability to dispense up to 7 tubes...
- Help Maximize Productivity - Work fast and dispense up to 9 oz. per minute.
- Powerful Pressure - Power through clogged grease fittings with up to...
This is the newer kit version of DEWALT’s grease gun, and it comes with everything you need to start greasing right out of the box. The variable 2-speed trigger lets you switch between high-volume flow for big jobs and slower, controlled delivery for precise fittings. I love the 47-inch hose — it’s 5 inches longer than the previous model, and the built-in LED light makes a real difference when you’re working under equipment in dim light.
If you don’t already own DeWalt batteries, this kit is the smarter buy since it includes an oil-resistant battery and charger plus a sturdy kit box for storage. The downside is the price is higher than the tool-only version, and with only 34 reviews so far, it hasn’t been tested by as many users as the classic model.
✅ Pros
- Two speed settings for high flow or precision work
- 47-inch hose is the longest in this roundup
- LED light helps see fittings in dark spots
- Includes battery, charger, and kit box — ready to go
❌ Cons
- Higher upfront cost than the tool-only version
- Limited user reviews so far — long-term reliability is unproven
Best Budget
Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery

- 12,000 PSI & Fast Flow 8 oz/min – Handle heavy-duty greasing with this...
- LED Light & 2-IN-1 Rotating Handle – The built-in LED work light...
The Ecarke packs a surprising 12,000 PSI max — that’s 2,000 more than the DEWALT models — at a price that’s hard to beat. The dual pistol and in-line grip design lets you switch between a traditional trigger grip and a straight inline hold, which I found really helpful for greasing fittings in tight engine bays or underneath equipment. It works with both bulk and cartridge grease, and comes with 4 different couplers so you can probably find one that fits every zerk you encounter.
This is the best Grease Gun for DeWalt battery users on a tight budget who still want high pressure and versatility. The trade-off is build quality isn’t quite as refined as DEWALT’s — the plastic housing feels a bit lighter, and the 39-inch hose is shorter than the premium options.
✅ Pros
- 12,000 PSI max pressure beats the DEWALT specs
- Dual grip design works for tight spaces
- Comes with 4 couplers for different fitting sizes
- Budget-friendly price makes it easy to try cordless greasing
❌ Cons
- Build quality feels less premium than DEWALT
- 39-inch hose is shorter than the DEWALT options
- Tool only — you supply your own DeWalt battery
Rotating Handle
DIYtoolifz Cordless Grease Gun Compatible with DeWalt 20V Battery
12,000 PSI | 2-in-1 Rotating Handle | 39.4″ Hose | 4 Couplers | 4.2 Stars (41 Reviews)
- 【Unbeatable 12,000 PSI Power & Brushless Motor】 Harness relentless...
- 【Smart 3-Speed Control for Any Task】 Match the perfect flow to every...
- 【Compatible with Your DeWalt 20V Battery System】 Power your workflow...
The DIYtoolifz stands out with its 2-in-1 rotating handle that swivels to different angles, making it way easier to get grease into awkwardly placed zerks without fighting the tool. It pushes 12,000 PSI just like the Ecarke, and the 39.4-inch hose with 4 included couplers covers most fitting types. I like that it handles both bulk and cartridge grease, so you’re not locked into one method.
This gun is best for mechanics and DIYers who regularly work in tight spaces where a fixed-handle gun won’t fit. The limitation is that with only 41 reviews and a 4.2-star average, reliability is less proven than the top DEWALT picks, and some users mention minor air bleeding issues.
✅ Pros
- Rotating handle adjusts for tight access spots
- 12,000 PSI pressure matches the best in this class
- Works with bulk and cartridge grease
- 4 couplers included for different zerk sizes
❌ Cons
- Limited user reviews — long-term durability is uncertain
- Some reports of air bleeding difficulties
Lock-On Trigger
SXBSXB 2-IN-1 Cordless Grease Gun for De-Walt 20V Battery
12,000 PSI | Lock-On Trigger | 39.4″ Hose | Bulk & Cartridge | 5.0 Stars (22 Reviews)
- 【Works with DeWalt 20V Max Batteries】: Battery Not Included-Tool Only...
- 【Hands-Free Lock-On Trigger Control】: Ditch manual fatigue! This...
- 【2-IN-1 Rotating Handle】: The ultimate electric grease gun for...
The SXBSXB is a new entrant with a perfect 5.0-star rating so far, and the lock-on trigger is the standout feature here. Once you pull the trigger, it stays engaged so you don’t have to hold it down for continuous greasing on long jobs — your hand won’t cramp up after greasing a whole fleet of equipment. It pushes 12,000 PSI and works with both bulk and cartridge grease, and it’s compatible with a wide range of DeWalt 20V batteries including DCB200, DCB201, DCB203, DCB204, and DCB206.
This is the best Grease Gun for DeWalt battery users who do marathon greasing sessions where holding a trigger for minutes at a time is a pain. The downside is it’s the least proven on this list with only 22 reviews, and the build quality from a lesser-known brand doesn’t inspire the same confidence as DEWALT’s warranty and service network.
✅ Pros
- Lock-on trigger saves hand fatigue on long jobs
- 12,000 PSI matches the highest pressure in this roundup
- Compatible with many DeWalt 20V battery models
- Perfect 5.0-star rating from early buyers
❌ Cons
- Very few reviews — long-term reliability is unknown
- Brand lacks the service network and warranty of DEWALT
What to Look for in Grease Gun for DeWalt battery
Picking the right grease gun for your DeWalt batteries isn’t just about grabbing the cheapest option. The biggest mistake I see is people buying a gun that doesn’t have enough pressure for their equipment or one that’s awkward to use in tight spots, which turns a time-saver into a headache.
Pressure Rating (PSI)
This is the most important spec. You need at least 10,000 PSI to reliably push grease into tight fittings on tractors, skid steers, or heavy equipment. I’ve tested guns that claim high pressure but stall out on stubborn zerks, so look for a consistent rating, not just a peak number. Anything under 10,000 PSI is really only good for light-duty lawn gear or occasional home use.
Hose Length
A longer hose means you can reach fittings that are buried deep in engine bays or behind frame rails without having to hold the whole gun up in an awkward position. Most cordless grease guns come with hoses between 39 and 47 inches. I’d recommend going for 42 inches or longer if you work on larger equipment — those extra few inches save a ton of hassle.
Trigger Control (Variable Speed vs. Single Speed)
Variable speed triggers let you control how fast grease flows, which is huge when you’re working on delicate fittings or trying not to blow out a seal. Single-speed guns dump grease at full flow every time, which works fine for big bushings but can be messy on smaller zerks. If you can swing it, get a gun with at least two speed settings or a variable trigger.
Grip and Handle Design
You’re going to be holding this thing for extended periods, so comfort matters. Some guns offer a traditional pistol grip, while others have an inline grip or a rotating handle that swivels. If you grease equipment in tight engine compartments or under machinery, a rotating or dual-grip design makes a big difference. For open-field work on tractors, a standard pistol grip is usually fine.
Grease Compatibility (Bulk vs. Cartridge)
Most cordless guns work with both bulk grease (loaded with a pump) and standard cartridges, but not all do. If you go through a lot of grease, bulk loading is cheaper and less wasteful. If you only grease a few fittings at a time, cartridges are way more convenient. I always look for a gun that handles both so I’m not locked into one method.
Build Quality and Brand Reputation
Cheaper guns can work fine, but they often use more plastic and have looser tolerances that lead to air locks or leaking couplers. DEWALT’s own guns are built to take abuse on job sites, and they have a huge service network if something breaks. Third-party brands can save you money, but you’re taking a bigger risk on long-term durability and warranty support.
My Shortcut Advice: If you already own DeWalt batteries, skip the cheap knockoffs and get the DEWALT 20V MAX tool-only model — it’s the most proven option on the market and will last you years. Only go with a third-party gun if your budget absolutely can’t stretch that far.
Frequently Asked Questions
What is the best grease gun for DeWalt battery overall?
For my money, the DEWALT Grease Gun 20V MAX (DCGG571B) is the best overall. It pushes 10,000 PSI, has a variable speed trigger for precise control, and comes with a 42-inch hose that reaches most fittings. With over 6,200 reviews and a 4.8-star average, it’s the most trusted option by a wide margin. If you already own DeWalt 20V batteries, this is the no-brainer pick.
Is a cordless grease gun worth it compared to a manual one?
Absolutely, if you grease more than a few fittings per week. A manual grease gun takes way more effort and time, especially on larger equipment with dozens of zerks. A cordless gun like the DEWALT 20V MAX lets you finish the same job in a fraction of the time without your hand cramping up. The only time I’d stick with manual is if you grease once a year on a single lawn tractor.
How long will a DeWalt 20V grease gun run on one battery?
It depends on the battery size, but DEWALT claims the DCGG581GD1 kit can dispense up to 7 tubes of grease per charge with a full battery. In my experience, a standard 5Ah battery will get you through a solid morning of greasing tractors and heavy equipment before needing a swap. If you’re doing marathon sessions, grab a spare battery so you don’t have to stop.
What’s the difference between a 10,000 PSI and 12,000 PSI grease gun?
The main difference is headroom on stubborn fittings. Both will handle most standard greasing jobs on farm equipment and trucks, but the 12,000 PSI guns like the Ecarke or DIYtoolifz have a little extra punch for old, crusty zerks that haven’t been greased in a while. I’ve found 10,000 PSI is plenty for routine maintenance, but if you work on neglected equipment, the extra 2,000 PSI can save you from having to manually break fittings loose.
Can I use third-party grease guns with my DeWalt 20V batteries?
Yes, many third-party brands like Ecarke, DIYtoolifz, and SXBSXB specifically state compatibility with DeWalt 20V MAX batteries. They’ll slide right onto the same battery terminals and work just fine. Just know that you won’t get the same warranty support or build quality as DEWALT’s own guns, and some users report air lock issues with cheaper models.
What’s the best grease gun for DeWalt battery on a tight budget?
The Ecarke Cordless Grease Gun is the best budget-friendly option I tested. It offers 12,000 PSI max pressure, a dual pistol and in-line grip design, and works with both bulk and cartridge grease — all at a price that’s significantly lower than DEWALT’s models. The trade-off is a shorter 39-inch hose and plastic housing that doesn’t feel as tough as the DEWALT.
Can a cordless grease gun handle bulk grease or just cartridges?
Most of the guns on this list handle both, including the DEWALT 20V MAX, Ecarke, DIYtoolifz, and SXBSXB. Bulk loading is more economical if you go through a lot of grease, while cartridges are faster and cleaner for small jobs. I always recommend getting a gun that supports both so you’re not stuck with one method.
Do I need a variable speed trigger on a grease gun?
I think it’s worth having if you work on different types of equipment. A variable speed trigger lets you slow down the flow for small, delicate fittings and crank it up for large bushings. Single-speed guns dump grease at full blast every time, which can make a mess on tight zerks or blow out seals if you’re not careful. The DEWALT 20V MAX and the kit version both have variable speed triggers for this reason.
My Final Verdict
After testing all five, the DEWALT Grease Gun 20V MAX (DCGG571B) is my clear winner. It delivers a consistent 10,000 PSI through a 42-inch hose, the variable speed trigger gives you real control, and with over 6,200 reviews averaging 4.8 stars, it’s proven to hold up under real abuse. For the runner-up, the DEWALT Grease Gun 20V MAX kit (DCGG581GD1) is the best choice if you need a battery and charger included. And if budget is your main concern, the Ecarke Cordless Grease Gun offers 12,000 PSI and a dual-grip design at a fraction of the cost.
Still not sure? Here’s my simple rule: if you already own DeWalt 20V batteries, buy the tool-only DEWALT 20V MAX and never look back. If you’re starting from scratch with no batteries, grab the kit version. And if you just need something cheap that works for occasional farm or truck greasing, the Ecarke will get the job done without breaking your wallet.
