DIYtoolifz Cordless Grease Gun for Milwaukee 18V — 12,000 PSI, 3-Speed Brushless Power (Tool Only)
Product description
What it is
The DIYtoolifz cordless grease gun is a high-pressure, brushless grease gun designed to run on Milwaukee 18V batteries (battery and charger not included). It supports both cartridge and bulk grease loading, making it a flexible choice for shop and field tasks. With a stated 12,000 PSI and a 3-speed control, it’s built to tackle stubborn fittings and routine maintenance alike.
How it works and what it delivers

On paper, the tool uses a brushless motor for cooler operation and longer life, which can matter for longer greasing sessions. The 3-speed dial offers Low (5 oz/min), Medium (7 oz/min), and High (9 oz/min) flow, allowing you to adjust the rate to delicate fittings or heavy-duty jobs. A 39.4” hose and four professional couplers are included, so you can reach different angles and hard-to-access points without swapping gear. The kit also includes a few practical features: a built-in LED light for dim areas, a non-slip kickstand for stable, hands-free use, a steel-braided high-pressure hose, and a quick-purge valve to eliminate airlocks at startup.
Pros and potential limitations


Pros: high max pressure helps with tight or clogged fittings, battery compatibility lets you leverage existing Milwaukee packs, 2-in-1 loading adds flexibility and potential cost savings, the kit comes with multiple couplers and a long hose for versatility, user-friendly features like LED light and quick purge can improve real-world use. Limitations: this is a bare-tool sale, so you’ll need compatible Milwaukee 18V batteries and a charger if you don’t own them already. Some users may find 12,000 PSI more than needed for small projects, and performance will depend on your battery capacity and grease viscosity. The description does not specify battery runtime, which can influence how long you can work between charges.

Who it’s for
If you already own Milwaukee 18V batteries and frequently service heavy equipment, this tool aims to reduce refilling and speed up tough grease jobs. It can be particularly appealing for pro users who need both cartridge and bulk grease workflows in a single device, plus the flexibility of a long hose and multiple couplers.
Who might want to skip it

Not ideal if you don’t plan to use Milwaukee 18V batteries, since the tool is sold as a bare tool. If you only occasionally grease small fittings or you’re buying on a tight budget, a simpler, lower-cost option with a shorter warranty or fewer accessories might make more sense.


When it makes sense to buy
Consider this grease gun if you value high pressure and fast throughput for heavy machinery, want to reuse existing Milwaukee batteries, and prefer a kit with multiple couplers and a long hose for access in tight spots. The 2-in-1 loading option also helps reduce waste and control costs when you switch between cartridge and bulk grease.

What to check before buying
- Confirm you have Milwaukee 18V batteries and a compatible charger to run the tool.
- Decide if you’ll use cartridge grease or bulk grease most often, since the 2-in-1 design supports both.
- Consider your typical reach and access points, a 39.4” hose is generous, but your workspace may demand different configurations.
- Keep expectations realistic about runtime and performance—high pressure is beneficial, but battery capacity matters for longer sessions.
Practical use case



Imagine you’re servicing a tractor’s hydraulic fittings after winter. You switch to the High flow setting to push grease through stubborn ports, use the LED light to spot the exact entry point, and rely on the kickstand to keep your hands free while you connect a new coupler. You can swap quickly between cartridge and bulk grease as needed without buying a separate tool for each workflow.
Comparison context
If you’re weighing this against a basic gun or a lower-pressure option, the big differentiator here is the 12,000 PSI capability, the brushless motor for durability, and the flexibility of cartridge/bulk loading with a Milwaukee 18V battery ecosystem. For lighter maintenance tasks or intermittent use, a simpler tool might suffice, for heavy equipment maintenance, this model aims to balance power, versatility, and battery compatibility.

Is it worth it?
Should you buy it? It depends on your setup and needs. If you already rely on Milwaukee 18V batteries, perform heavy grease jobs, and want a comprehensive kit out of the box, this could be a compelling option. If your tasks are light, or you don’t own Milwaukee batteries, you may want to explore lighter or battery-agnostic alternatives.
FAQ
- Do I need to buy Milwaukee batteries separately? Yes, batteries and charger are not included.
- Can I use standard 14 oz cartridges with this gun? Yes, it supports 14 oz cartridges as part of the 2-in-1 loading design.
- Is the hose length sufficient for large machines? The 39.4” hose provides ample reach for many setups, but very large equipment might still require additional flexible extension.
