milwaukee M18 2-Speed Grease Gun - Bare Tool, 10,000 PSI High-Pressure with 48" Flexible Hose

The Milwaukee M18 2-Speed Grease Gun (2646-20) is a cordless, high-pressure tool that delivers up to 10,000 PSI and precise grease dispensing for professional service and maintenance work.

The M18 2-Speed Grease Gun is built to combine raw pressure with control, letting technicians choose between maximum force or higher flow for different lubrication tasks. This bare-tool model fits into the M18 battery ecosystem and includes user-friendly touches such as a pre-set grease counter, an LED work light, and a plunger rod with volume markings. Robust features like a 48" flexible hose and a stand-up design improve access and reduce fatigue on the jobsite.

How does the 2-speed system improve performance?

The two-speed gearbox lets you switch between a high-pressure mode for stubborn fittings and a high-flow mode for quick filling. That flexibility reduces time spent battling stuck lines and prevents over-amping when filling larger bearings.

• Select high pressure for tight or sealed fittings up to 10,000 PSI
• Choose high flow to move grease faster into larger components
• Switching saves time and battery life versus using a single-mode tool

What precision controls does the tool offer?

The integrated pre-set grease counter lets you program exact dispenses to repeat consistent lubrication volumes, improving maintenance accuracy. A plunger rod with graduated markings gives a quick visual check of grease remaining in the barrel, and the lock-on/lock-off trigger helps prevent accidental dispenses.

• Patent-pending pre-set counter for repeatable grease amounts
• Plunger rod markings show remaining grease level
• Lock-on/lock-off trigger for controlled operation and safety

How accessible and serviceable is the grease gun?

A 48" flexible hose reaches recessed or tight lubrication points without awkward repositioning. The tool includes an air bleeder valve for faster priming and is compatible with a clear barrel accessory to monitor grease type and quantity visually.

• Long 48-inch flexible hose for hard-to-reach fittings
• Air bleeder valve speeds priming to reduce downtime
• Compatible with a clear barrel accessory for visual monitoring

What user comforts and on-board features are included?

Milwaukee added small but practical features to reduce fatigue and improve usability during long shifts. The tool can be stood upright and used with a shoulder strap for more ergonomic handling, while the integrated LED illuminates dark work areas for precise connections.

• Stand-up design and shoulder strap capability to reduce strain
• On-board LED light for improved visibility in low light
• Bare-tool configuration fits into the M18 battery system for cross-tool compatibility

Who is this for: The Milwaukee M18 2-Speed Grease Gun 2646-20 is aimed at professional mechanics, fleet technicians, and industrial maintenance teams who need a durable, cordless grease solution with both high-pressure capability and precise volume control. If you already use Milwaukee M18 tools or require repeatable grease dispenses, this bare tool provides the mechanics-focused features and reach to speed up routine lubrication and service tasks.
