DIYtoolifz Cordless Grease Gun for DeWalt 20V
If you already own DeWalt 20V batteries, buying a dedicated cordless grease gun often feels like a waste of money. The DIYtoolifz Cordless Grease Gun Compatible with DeWalt 20V Battery solves this by letting you use your existing power cells. It delivers high-pressure lubrication without the bulk or cost of proprietary battery systems.
Our research shows this tool bridges the gap between manual pumps and expensive OEM cordless units effectively. You get consistent flow rates and portability that make routine maintenance less of a chore. Let’s break down whether this adapter-style design holds up under real-world pressure demands.
What it is
This unit is a battery-powered lubricator designed specifically to interface with DeWalt 20V MAX lithium-ion packs. Unlike traditional manual grease guns that rely on user strength, this model uses an electric motor to generate consistent pressure. It competes in the same space as established brands like Lincoln Industrial and Bosch, but positions itself as a value-focused alternative.
The "compatible" nature means you aren't locked into a single ecosystem's battery costs. If you have spare DeWalt tools, this becomes a seamless addition to your workshop. It handles both cartridge and bulk-loading methods, offering flexibility for different job sizes.
Setup & first impressions
Aggregate user reviews highlight that assembly takes less than five minutes out of the box. Verified buyers consistently mention that the hose coupler threads engage smoothly without cross-threading issues common in cheaper imports. The build quality feels substantial, though some users note the plastic housing lacks the rubberized grip texture found on premium models.
First-time setup involves attaching the hose and selecting your grease type. Manufacturer documentation indicates the device supports standard NLGI Grade 2 greases. Many technicians report that the initial priming process is straightforward once the air purge button is understood.
The rotating handle feature receives praise for reducing wrist strain during extended sessions.

Daily-use experience
Performance
The 12,000 PSI maximum pressure rating ensures this gun can force grease into stubborn fittings. In our analysis of field reports, mechanics noted that clearing blocked zerks took seconds rather than minutes compared to manual pumps. The motor maintains steady output until the battery depletes, avoiding the erratic pulsing seen in lower-quality electronics.
However, performance depends heavily on battery health. Users with older 20V packs may notice reduced throughput speed. For optimal results, fresh 4.0Ah or larger batteries are recommended.
This consistency helps when working on large fleets where time savings matter significantly.
Comfort & ergonomics
The 2-in-1 rotating handle is a standout feature for comfort. It allows you to switch between pistol-grip and inline configurations easily. This adaptability reduces fatigue when reaching into tight spaces like wheel wells or undercarriages.
Aggregate feedback suggests the weight distribution feels balanced even when fully loaded.
Some reviewers mention the trigger resistance is slightly stiff initially. After a few uses, it softens up, but those with hand injuries might find it challenging. The textured grip provides decent hold despite the lack of premium rubber coating.
Overall, it beats manual levers for repetitive tasks.
Battery / longevity
Since this is a "Tool Only" kit, battery life mirrors your DeWalt pack capacity. A typical 2.0Ah battery lasts through roughly 15, 20 full cartridges before needing a swap. Larger 6.0Ah packs extend this significantly, making them ideal for all-day commercial use.
Charging times align with standard DeWalt protocols. Most users appreciate not having to manage yet another proprietary charger. Just ensure you keep enough charged spares on hand.
Running out mid-job interrupts workflow more than swapping magazines does.
Build quality
The housing uses durable polymer construction resistant to shop chemicals. While it doesn't feel indestructible like metal-bodied Lincoln guns, it withstands drops from workbench height according to user testimonials. The hose connection points appear reinforced to prevent leaks under high pressure.
Long-term durability remains to be seen since this is a newer market entrant. However, early failure rates reported online are low. Regular cleaning prevents grease buildup around the nozzle mechanism.
Treat it well, and it should serve reliably for years.
✓ Pros
- Uses existing DeWalt 20V batteries, saving significant upfront costs
- High 12,000 PSI pressure clears difficult or rusted fittings quickly
- Rotating handle offers versatile positioning for awkward angles
- Dual loading capability accommodates both cartridges and bulk tubs
- Lightweight design reduces arm fatigue during prolonged maintenance sessions
✗ Cons
- No battery included, requiring ownership of DeWalt packs beforehand
- Plastic body feels less robust than all-metal industrial competitors
- Limited customer support network compared to major tool brands
- Trigger stiffness may bother users with limited hand strength
Who should buy it
Buy it if you…
You maintain trucks, tractors, or construction equipment regularly. If you already stock DeWalt batteries, this tool integrates perfectly into your existing workflow. It saves you from purchasing a separate charging system.
Small business owners who prioritize cost-efficiency will appreciate the ROI here.
It also suits hobbyists tackling weekend projects on older vehicles. The high pressure helps revive seized joints without excessive effort. You don't need industrial certification backing, just reliable function.
This fits the bill for anyone wanting professional results on a DIY budget.
Skip it if you…
You operate in environments requiring strict OSHA-compliant branded gear. Some corporate fleets mandate specific manufacturers for liability reasons. Additionally, if you lack DeWalt batteries entirely, the total cost rises sharply.
Buying the tool plus two batteries might exceed the price of a complete Milwaukee set.
Users needing extreme durability for daily abuse in harsh mines or quarries should look elsewhere. Metal-bodied alternatives offer better impact resistance. This plastic unit is tough but not invincible against concrete floors.
Match the tool to your actual wear-and-tear expectations.
Better alternatives
Consider the Lincoln PowerLuber 1200 if you need unmatched reliability and brand support. It’s pricier but built for decades of service. Alternatively, the Milwaukee M18 Fuel Grease Gun offers superior torque handling if you’re already invested in their ecosystem.
Both provide heavier-duty constructions but at higher entry costs.
Frequently Asked Questions (FAQ)
Does it work with old DeWalt batteries?
Yes, it accepts any DeWalt 20V MAX slide-pack battery. Older NiCd versions won’t fit, but most Li-Ion packs from the last decade work fine. Ensure contacts are clean for best connectivity.
Performance scales with battery age, so fresher cells yield faster cycling speeds.
Can I use bulk grease instead of cartridges?
Absolutely. The dual-loading design lets you unscrew the head and load directly from a tub. This is much cheaper per ounce for high-volume users.
Just remember to prime thoroughly after switching modes. Bulk loading requires slightly more cleanup but saves money long-term.
Is the hose replaceable if damaged?
Manufacturer specs indicate the hose is integrated but repairable via standard fittings. Replacement hoses are available separately on Amazon. Keep connections tight to prevent leaks at 12,000 PSI.
Regular inspection prevents sudden failures during critical jobs.
How loud is the motor operation?
User reports describe it as moderately loud, comparable to a drill press. It’s not silent, but manageable without ear protection for short bursts. Extended use in enclosed spaces might warrant hearing guards.
The noise comes from the hydraulic pump mechanism engaging.
What happens if the fitting is completely blocked?
The 12,000 PSI output usually forces open minor blockages. For severe cases, disconnect and inspect the zerk nipple manually. Never force the trigger continuously against a dead-end restriction.
Doing so risks overheating the motor or bursting seals prematurely.
Final verdict
We rate this 4.2/5. It excels as a cost-effective solution for DeWalt battery owners. The balance of power, portability, and price makes it hard to beat in its niche.
You sacrifice some premium build materials but gain functional parity with top-tier brands.
Buyers who already possess the necessary power source win big here. Those starting from scratch must calculate total system costs carefully. For most workshops, this represents smart, pragmatic tool acquisition.
