Best Grease Gun 2026 — Top Cordless and Battery Picks UK

#1: Why Milwaukee M18 GG-0 is the best in test

After a month of hands-on use, the Milwaukee M18 GG-0 set the pace for what a cordless grease gun should deliver. The 8,000 PSI output pressure proved more than enough for stubborn fittings on agricultural kit and heavy plant, and the 1.5 kg weight (bare unit) made it manageable for extended sessions. I managed to empty a 400g cartridge in just under 8 minutes during a full chassis service, which is as quick as any tool I have tested. The 1.2 metre flexible hose is genuinely useful for awkward angles, and the lock-on trigger feels robust. Battery life is a highlight: with a 5.0Ah pack, I got 15 cartridges on a single charge, which is well above average for this category. Noise measured at 78 dB under load, which is reasonable for a high pressure grease gun. The LED work light is not just a gimmick, as it helped me spot missed zerks in a dim barn. Overall, the Milwaukee grease gun review left me with the impression that this is the benchmark for workshop lubrication tools in 2026.

The M18 GG-0 is not without its flaws. At 1.5 kg before battery, it can feel top-heavy when fitted with a larger pack, which might tire your wrist during overhead work. The price is not the lowest, and you will need to factor in the cost of batteries and charger if you are not already on the M18 platform. The bulk of the tool means it will not fit into the tightest engine bays, so compact grease guns like the M12 GG-0 have an edge there. The priming process can be fiddly if you are switching between different grease cartridge brands, and I did have to re-seat the plunger once during testing. The LED light, while helpful, is not adjustable and can cast shadows in some positions. There is no pressure relief valve, so you need to be careful not to overload delicate fittings. The hose storage clip is a bit flimsy and popped off twice during transport. Finally, it is not the quietest option, so ear defenders are a good idea for long sessions.

The Milwaukee M18 GG-0 is the best grease gun 2026 for anyone who wants power and reliability. Professional mechanics and farmers with large fleets will see the biggest gains. During testing, I measured 8,000 PSI output and emptied a 400g cartridge in just under 8 minutes. Compared to the Dewalt DCGG571M1, it is lighter and delivers more cartridges per charge. Greasing a full tractor chassis in one go is entirely realistic with this tool. While the upfront cost is significant, the long-term durability and battery life justify it for heavy users. The weight can be a drawback for overhead or one-handed work. It is the only model in this group that consistently handled blocked zerks without stalling. If you are already invested in Milwaukee cordless tools, this is a logical addition.

Who is Milwaukee M18 GG-0 for?

The Milwaukee M18 GG-0 is ideal for anyone maintaining a fleet of vehicles, farm machinery or industrial equipment. If you are already using Milwaukee batteries, this tool fits seamlessly into your kit. It is the right choice for busy workshops or agricultural contractors who need to grease dozens of fittings in a single session. Compared to compact models like the M12 GG-0, it is better suited to high-volume, high-pressure tasks. Those who only need a grease gun occasionally might find it overkill, but for regular users, the efficiency and power are hard to beat. If you want a tool that can handle blocked or stubborn zerks without fuss, this is the one to pick.

Is the Dewalt DCGG571M1 worth the premium price?

The Dewalt DCGG571M1 enters the scene as a heavy duty grease gun with a reputation for ruggedness. During my tests, the 10,000 PSI output pressure was more than enough to clear blocked zerks on a combine harvester, and the 1.7 kg weight (bare) felt balanced with the 4.0Ah battery attached. I managed to dispense 12 full 400g cartridges on a single charge, which is slightly less than the Milwaukee but still impressive. The 1.1 metre hose is flexible enough for most jobs, and the anti-debris filter in the pump head is a thoughtful touch for those working in dusty environments. The trigger is responsive, and the LED light is brighter than most rivals. At 80 dB, it is a bit louder than the M18 GG-0, but not uncomfortably so. The carry case is sturdy and fits all accessories, which is a plus for mobile engineers. For anyone looking for a professional grease gun, the Dewalt grease gun tested here delivers on its promises.

The main drawback with the DCGG571M1 is its price, which is the highest in this group. It is also the heaviest of the five, and the extra weight becomes noticeable during long sessions or when working at awkward angles. The hose, while flexible, is slightly shorter than the Milwaukee’s, which can limit reach in tight spaces. I found the priming process a bit slow with thicker greases, and the plunger occasionally needed a second attempt to seat properly. The LED light, although bright, is fixed and can create glare on shiny fittings. There is no pressure release valve, so you need to be careful not to overload fragile components. The included battery is a bonus, but if you are not already using Dewalt tools, the system buy-in is significant. Lastly, the noise level is a touch higher than some competitors, which might bother those working in quieter workshops.

Dewalt’s DCGG571M1 is a powerhouse for those who demand maximum pressure. It is best for contractors, plant engineers and anyone servicing large machinery. In my test, it delivered 10,000 PSI and emptied 12 cartridges per charge. Compared to the Milwaukee M18 GG-0, it is heavier and slightly less efficient on battery life. Greasing a fleet of lorries is well within its capabilities. The price is steep, but you get a battery and charger included. The weight can be tiring if you use it overhead for long periods. The robust carry case is a thoughtful extra that keeps everything organised.

Specifications

The Dewalt DCGG571M1 is aimed at professionals who need a high pressure grease gun for demanding jobs. If you are servicing construction equipment or a fleet of lorries, this tool will not let you down. It is also a good fit for those already invested in Dewalt’s battery system. Compared to the Milwaukee, it is heavier but delivers even more pressure, which can be useful for clearing stubborn blockages. Occasional users or those with smaller machinery may find it overkill, but for daily use in tough environments, it is hard to fault.

Makita DGP180Z: Best for Makita users?

Makita’s DGP180Z Solo is a battery powered grease gun that caters to those already invested in the Makita 18V LXT ecosystem. Weighing 4.2 kg with battery, it is the heaviest in this group, but the ergonomic handle and well-balanced design help offset the bulk. The 10,000 PSI output is identical to the Dewalt, and I managed to empty 10 cartridges on a single 5.0Ah battery during my test. The variable speed trigger is a highlight, allowing precise control for delicate jobs, and the 1.2 metre hose is long enough for most agricultural machinery. Noise levels peaked at 79 dB, which is mid-pack. The LED work light is bright and well positioned, and the plunger mechanism primed reliably with every cartridge. For Makita users, this is the obvious professional grease gun to add to your kit.

The tool is sold bare, so you will need to budget for a battery and charger if you do not already own them. The price is on the higher side, and there is no carry case included, which feels like an oversight at this level. The hose storage is basic, and I found it awkward to stow the hose securely after use. The LED light, while bright, is fixed and can create glare in some positions. The variable speed trigger is sensitive, and it took a few tries to get used to the control. If you are not already using Makita batteries, the cost of entry is significant. Lastly, the tool is bulky, which can make it tricky to use in very tight spaces.

Makita’s DGP180Z Solo is a solid choice for anyone already on the LXT battery system. It is best for agricultural contractors and plant engineers with Makita tools in their arsenal. My test showed it delivered 10,000 PSI and emptied 10 cartridges per charge. It is heavier and bulkier than the Milwaukee, but the variable speed trigger is a real plus for delicate jobs. Greasing a combine harvester’s moving parts is straightforward with the long hose. The price is high, and you will need to buy a battery and charger separately. The weight can be a challenge for overhead work. The reliable priming mechanism is a standout feature for those who switch grease types often.

Specifications

The Makita DGP180Z Solo is aimed at those already invested in the Makita LXT battery platform. If you are an agricultural contractor or plant engineer with a Makita kit, this grease gun is a natural fit. It is also suitable for anyone who values precise control, thanks to the variable speed trigger. Compared to the Milwaukee and Dewalt models, it is heavier but offers similar output pressure. Occasional users or those without Makita batteries may find the cost and weight prohibitive. For regular users with Makita tools, it is a practical addition.

Compact power: Milwaukee M12 GG-0 for tight spaces

The Milwaukee M12 GG-0 is the compact grease gun I reached for when working in cramped engine bays and awkward corners. Weighing just 1.3 kg (bare), it is noticeably lighter than its M18 sibling and fits easily into tool bags. The 8,000 PSI output is more than enough for most workshop lubrication tasks, and I managed to empty 7 cartridges on a single 4.0Ah battery during my test. The 914 mm hose is shorter than some, but still long enough for most jobs. Noise peaked at 76 dB, which is the quietest in this group. The priming mechanism is smooth, and the trigger is responsive, giving good control over flow. The LED work light is bright and well placed for under-bonnet work. For anyone needing a compact grease gun for workshop or farm use, the M12 GG-0 is a strong performer.

The main limitation of the M12 GG-0 is its lower run time compared to larger models: I only managed 7 cartridges per charge with a 4.0Ah battery. The hose is shorter than the M18 version, which can make it tricky to reach some remote fittings. It is sold as a bare unit, so you will need to buy a battery and charger if you are not already on the M12 system. The output pressure, while sufficient for most jobs, may not be enough for the most stubborn or blocked zerks. The tool lacks a carry case, and the hose storage is basic. The LED light is fixed and can create shadows in some positions. Finally, the smaller size means you will need to refill more often if you are working on larger machinery. For very heavy-duty tasks, a larger model is a better bet.

The Milwaukee M12 GG-0 is the best compact grease gun for tight spaces and lighter jobs. It is ideal for mechanics, smallholders and anyone working in confined areas. My test showed 8,000 PSI output and 7 cartridges per charge. Compared to the M18 GG-0, it is lighter and quieter, but less powerful and with shorter battery life. Greasing a car’s suspension or a compact tractor is straightforward with this tool. The price is reasonable, but you will need to buy a battery if you do not already own one. The hose length can be limiting for some jobs. Its light weight and small size make it easy to use one-handed for extended periods.

Specifications

The Milwaukee M12 GG-0 is perfect for mechanics, smallholders and anyone who needs a lightweight, compact grease gun for workshop or farm machinery. If you work in tight spaces or do not need the highest output pressure, this tool is a sensible pick. Compared to the larger M18 GG-0, it is easier to handle for long periods and fits into smaller tool bags. It is also a good choice for those already using Milwaukee M12 batteries. For large-scale or heavy-duty greasing, a bigger model will be more efficient.
