Milwaukee M18 Cordless 2-Speed Grease Gun (Tool Only) — 48" Hose, 10,000 PSI, High Flow

This cordless grease gun from Milwaukee is designed for heavy-duty maintenance tasks where speed, reach, and control matter. It operates on the M18 platform (battery sold separately) and combines a powerful hydraulic system with features meant to minimize downtime: a 48" flexible hose for access, a pre-set grease counter for repeatable dosing, and an air-bleeder valve to simplify priming. The package includes the gun body, a 48" hose with spring guard, and a high-pressure coupler.

How does this grease gun handle high-pressure applications?

The M18 grease gun produces a maximum operating pressure of 10,000 PSI so it can push heavy grease into tight fittings and through longer lines. Its two-speed gearbox lets you switch between high-pressure and higher-flow modes depending on the job.

• Industry-leading 10,000 PSI max operating pressure
• Two-speed operation for pressure vs. flow control
• High-pressure coupler withstands demanding service tasks

Will it help me work faster on service rounds?

Yes — the gun offers a top flow-rate of up to 10 ounces per minute to move grease into fittings quickly, and the lock-on/lock-off trigger reduces user fatigue during repetitive greasing. The pre-set grease counter dial helps you apply consistent amounts for repeatable maintenance cycles.

• Up to 10 oz./minute flow-rate for faster filling
• Lock-on/lock-off trigger for continuous operation options
• Pre-set grease counter dial for repeatable dispense volumes

Can it reach confined or awkward fittings?

The included 48" flexible hose with a spring guard extends reach into cramped or hard-to-access locations while protecting the hose from kinks and wear. The hose and high-pressure coupler combination lets you attach to recessed fittings without repositioning heavy components.

• 48" flexible hose for access behind panels and tight machinery
• Spring guard reduces hose abrasion and kinking
• High-pressure grease coupler secures to recessed zerks

How easy is it to set up and prime?

Priming is simplified with an integrated air-bleeder valve that vents trapped air to speed initial setup and restore full pumping performance. The tool-only packaging means you can pair it with any compatible M18 REDLITHIUM battery you already own to get started.

• Air bleeder valve for quick, tool priming and maintenance
• Compatible with M18 battery ecosystem (battery not included)
• Tool-only SKU lets crews integrate with existing M18 fleets

Who is this for? Maintenance technicians, fleet mechanics, agricultural operators, and facilities staff who need a portable, high-pressure lubrication solution will benefit from the Milwaukee M18 Cordless 2-Speed Grease Gun. It’s intended for professionals who require durable hardware, adjustable pressure/flow, and extended hose reach — especially where access or speed is critical. Note: this listing is for the tool only; M18 batteries and chargers are sold separately.
