---

### **Pros of the Milwaukee MLW2646-20 Grease Gun**

1. **Powerful and Reliable Motor**

The M18 FUEL platform is known for its durability and high torque output. This grease gun delivers consistent pressure, making it ideal for high-viscosity grease applications where other tools may struggle. The two-speed trigger allows for precise control, whether you need a steady flow or a quick burst of grease.

2. **Cordless and Battery-Powered**

As part of Milwaukee s M18 FUEL line, this tool runs on the company s high-capacity 18V lithium-ion batteries. This eliminates the need for cords, providing greater mobility and convenience, especially in tight or outdoor spaces. The tool is compatible with Milwaukee s REDLITHIUM batteries, which offer long runtime and fast charging.

3. **Durable Construction**

Milwaukee tools are built to withstand harsh conditions. The MLW2646-20 features a rugged, metal housing that resists dents, rust, and wear, making it suitable for industrial environments. The tool is also designed to handle frequent use without losing performance.

4. **Two-Speed Trigger**

The dual-speed trigger allows users to adjust the grease flow rate. The low speed provides a steady, controlled application, while the high speed delivers a quick burst, which is useful for sealing or lubricating tight spaces. This versatility makes it adaptable to various tasks.

5. **Compatibility with Milwaukee s Ecosystem**

The tool is part of Milwaukee s M18 FUEL system, which means it integrates seamlessly with other M18 tools and accessories. Users can easily swap batteries, use extension cords, or pair it with other Milwaukee power tools for a unified workflow. The tool also supports Milwaukee s wireless charging docks and battery management features.

6. **High Pressure and Volume Capacity**

The MLW2646-20 is designed to handle high-pressure applications, which is critical for greasing ball joints, wheel bearings, and other high-stress components. The grease gun can accommodate larger grease containers (up to 1 quart), reducing the need for frequent refills during extended use.

7. **Ergonomic Design**

The tool is designed with an angled handle and a comfortable grip, reducing user fatigue during prolonged use. The trigger is responsive, and the overall weight is balanced, making it easier to maneuver in tight spaces.

8. **Long Warranty**

Milwaukee offers a robust warranty (typically 3-year limited warranty) on this tool, reflecting its confidence in the product s durability. This provides peace of mind for users investing in a high-performance tool.

### **Cons of the Milwaukee MLW2646-20 Grease Gun**

1. **High Initial Cost**

The MLW2646-20 is a premium tool, and its price point is significantly higher than basic cordless or even manual grease guns. For casual users or those with minimal greasing needs, this may be an unnecessary expense. The cost of the tool itself, along with the required M18 batteries, can add up quickly.

2. **Dependency on Milwaukee s Proprietary Battery System**

While the M18 FUEL batteries are high-quality, they are proprietary to Milwaukee. This means users are locked into Milwaukee s battery ecosystem, which can be costly if you need to replace batteries frequently. Third-party batteries may not perform as reliably or safely.

3. **Battery Runtime Limitations**

Even with high-capacity batteries, the runtime for greasing tasks can be limited, especially if using high-viscosity grease or working in cold temperatures. Users may need to carry spare batteries or a charger to avoid interruptions, particularly in large-scale applications.

4. **Weight and Bulk**

The tool is heavier than manual or basic electric grease guns due to its battery and motor. While the design is ergonomic, some users may find it cumbersome after extended use, particularly if they are used to lighter tools.

5. **Grease Container Limitations**

While the tool can handle larger grease containers, the standard grease tubes (e.g., 1-quart cans) may not fit perfectly without adapters. Users may need to invest in compatible grease containers or adapters, adding to the overall cost.

6. **Learning Curve for Advanced Features**

The two-speed trigger and high-pressure capabilities require some familiarity to use effectively. Inexperienced users might struggle with controlling the grease flow, leading to waste or improper application. Proper training or practice may be needed to maximize the tool s benefits.

7. **Limited Availability of Accessories**

While Milwaukee offers a wide range of accessories for its M18 tools, not all greasing-specific attachments or adapters may be readily available. Users may need to source third-party solutions or wait for Milwaukee to release compatible accessories.

8. **Potential for Over-Greasing**

The high pressure and power of this tool can make it easy to over-grease components, which can lead to grease leaks, contamination, or damage to seals. Users must exercise caution and follow manufacturer guidelines to avoid this issue.

---

### **Conclusion**

The Milwaukee MLW2646-20 is an excellent choice for professionals, mechanics, and DIY enthusiasts who require a high-performance, durable grease gun for heavy-duty applications. Its powerful motor, cordless operation, and compatibility with Milwaukee s ecosystem make it a standout tool for users who prioritize reliability and performance. The two-speed trigger and high-pressure capabilities ensure versatility, while the tool s rugged construction ensures longevity in demanding environments.

However, the high cost, dependency on proprietary batteries, and potential learning curve may deter casual users or those on a tight budget. If you frequently grease high-stress components, work in industrial settings, or value the convenience of cordless tools, the MLW2646-20 is a worthwhile investment. For lighter or occasional use, a more affordable manual or basic electric grease gun might suffice.

---

### **Recommendation**

- You are a professional mechanic, industrial worker, or serious DIY enthusiast who needs a reliable, high-performance grease gun for demanding tasks.

- You already own or plan to invest in Milwaukee s M18 FUEL tool ecosystem, as this tool integrates seamlessly with other M18 tools and batteries.

- You prioritize durability, power, and cordless convenience over cost, and you can justify the higher upfront investment with long-term use.

- You frequently work with high-viscosity grease or in environments where a powerful, durable tool is essential.

- You have minimal greasing needs or only occasionally perform lubrication tasks, as a cheaper manual or basic electric grease gun would be more cost-effective.

- You are unwilling to commit to Milwaukee s proprietary battery system or cannot afford the ongoing cost of batteries and accessories.

- You prefer lighter tools or have ergonomic concerns, as the MLW2646-20 is heavier and more powerful than basic alternatives.

- You lack experience with high-pressure grease guns and are concerned about over-greasing or improper use.

For most professionals, the MLW2646-20 is a superior choice due to its performance and reliability. For casual users, however, it may not offer enough value to justify the cost. Always consider your specific needs and budget before making a purchase.
