DIYtoolifz Cordless Grease Gun — Milwaukee 18V Compatible, Tool Only, 12,000 PSI Brushless 3‑Speed (39.4" Hose)

The DIYtoolifz Cordless Grease Gun is a high-pressure, brushless, Milwaukee 18V-compatible tool designed to deliver up to 12,000 PSI with three selectable speeds and dual loading for cartridge or bulk grease.

Built for mechanics, fleet managers, and maintenance pros who need fast, reliable lubrication on heavy equipment, this cordless grease gun pairs high pressure with a brushless motor for improved runtime and durability. It accepts standard 14 oz cartridges or bulk grease, uses Milwaukee 18V batteries you may already own, and comes with a long hose plus multiple couplers to reach most grease fittings on vehicles, agriculture, or industrial machinery.

How does the three-speed control make greasing faster and more accurate?

The 3-speed dial lets you choose Low, Medium, or High flow to match the task. Lower speed is for precision work on small fittings; higher speeds clear clogged lines and fill heavy-duty points quickly. This flexibility reduces over-greasing and saves time across diverse maintenance jobs.

• Low: 5 oz/min for delicate or precision lubrication
• Medium: 7 oz/min for standard routine maintenance
• High: 9 oz/min to push through stubborn or high-volume fittings

Is it compatible with the batteries I already own?

Yes — the tool is designed to accept Milwaukee 18V batteries, letting you use an existing battery ecosystem without buying a new charger or pack. Batteries and charger are sold separately, and for best performance, a 4.0Ah or higher battery capacity is recommended. This compatibility reduces upfront cost and simplifies integration into workshops that already use Milwaukee 18V tools.

• Works with Milwaukee 18V battery system (battery not included)
• Recommended 4.0Ah or higher for optimal runtime
• Tool-only packaging lowers purchase price for multi-tool shops

What fittings and hose options come with the grease gun?

The kit includes a 39.4-inch flexible steel-braided hose and four professional couplers to cover nearly all common grease points. Included couplers handle angled, lock-on, pointed tip, and standard fittings so you can switch quickly between tasks. The hose and couplers are built for high pressure and frequent use on heavy equipment.

• 39.4" steel-braided flexible hose for reach and durability
• Four couplers: 90° angle, lock-on, pointed tip, and standard
• Extension pipe, wrenches, and a shoulder strap for convenience

How do I load grease and keep the tool ready on the job?

The 2-in-1 loading system accepts both standard 14 oz cartridges and bulk grease from a pail or drum, making it easy to switch depending on job volume and cost. A quick-purge valve clears airlocks for immediate operation, and the non-slip kickstand plus LED light improve hands-free setup and visibility in low-light areas. The blow-molded case keeps components organized for transport between sites.

• Cartridge loading for quick replacements and clean handling
• Bulk greasing option to lower cost per ounce on large jobs
• Quick-purge valve, LED work light, and kickstand for jobsite convenience
