Overview

The Milwaukee 2646-20 M18 2-Speed Grease Gun is a versatile bare tool designed for maintenance professionals who value control, reach, and portability. Built to run on Milwaukee’s M18 REDLITHIUM battery platform, this tool emphasizes precision and adaptability across demanding greasing tasks without sacrificing convenience. The gun’s battery-powered design helps reduce cord clutter and offers the flexibility to work in tight spaces where a corded unit would be cumbersome.

What makes this model stand out is its combination of raw power and purposeful features. With a patent-pending pre-set grease counter, technicians can dispense measured amounts of grease, supporting consistent service intervals. The compact form sits comfortably in hand, while the rugged build and thoughtful accessories keep pace with daily field work.

Power, Control, and Core Benefits

• Industry-leading 10,000 PSI max operating pressure for robust grease delivery
• 2-speed design to switch between high-pressure bursts and higher flow when precision is less critical
• Pre-set grease counter dial for repeatable dispensing and documentation
• Air bleeder valve enables quick priming, reducing setup time

Design for Accessibility and Ease of Use

• 48" flexible hose improves access to hard-to-reach fittings
• Lock-on / lock-off trigger enhances consistency and reduces hand fatigue during extended use
• Stand-up design and optional shoulder strap support for improved handling and reduced fatigue
• Compatibility with a clear barrel accessory to monitor grease levels at a glance

Real-World Scenarios and Versatile Performance

Ideal for automotive, industrial, and equipment maintenance tasks, this tool helps technicians tackle fittings on heavy machinery, agricultural equipment, and service bays. Expect confident grease delivery on stubborn fittings, simplified priming for quick starts, and the freedom to work off a single battery system across a growing Milwaukee tool family.

Key advantages to consider include the tool’s rugged construction, the visible grease-management cues from the plunger rod with markings, and the sense of reliability that comes from a system designed to cooperate with other M18 tools. While results will vary by application, the features are built to support smoother, more controlled greasing sessions without requiring extra cords or adapters.

What You Get and How It Fits Your Workflow

Because this is a bare tool, you’ll pair it with your existing M18 battery and charger. The combination offers compatibility with a broad Milwaukee ecosystem, helping you streamline tool storage and purchasing decisions. For technicians who already own M18 batteries, this grease gun integrates into daily workflows with minimal setup, enabling faster service turns without compromising control or reach.
