Buying guide

How to choose

Voltage Platform Selection

Milwaukee tools operate primarily on M18 or M12 platforms. The M18 system is designed for high-demand tasks, offering more power for heavy-duty drilling, driving, and grinding. Conversely, the M12 subcompact line prioritizes portability and maneuverability in tight spaces. When choosing a combo kit, assess whether your workload requires the high-torque output of the 18-volt batteries or the lightweight convenience of the smaller subcompact system. Ensure your existing battery inventory aligns with the platform you select, as batteries are often cross-compatible within their respective voltage families but do not interchange between the M12 and M18 systems.

Brushless vs. Brushed Motors

Brushless motor technology, featured in the 2892-22CT and M12 subcompact kits, generally offers increased efficiency and longer tool life compared to traditional brushed motors found in some legacy kits like the 2696-26. Brushless motors reduce friction, allowing for cooler operation and optimized energy consumption during repetitive tasks. If you prioritize long-term durability and consistent performance for daily professional or home-improvement projects, look for kits explicitly labeled as brushless. This technology helps maintain consistent speed and torque under load, which is critical when using impact drivers or compact angle grinders in challenging material applications.

Tool Count and Versatility

Combo kits range from two-tool sets to comprehensive eight-tool collections. The 2892-22CT and M12 subcompact kits provide the essential drill and impact driver duo, which covers most fastening and boring requirements. Larger sets, such as the 8-tool M18 kit or the 6-tool 2696-26 kit, are better suited for users building a workshop from scratch who need saws, lights, or specialty tools. Evaluate your specific project needs; purchasing a larger kit can provide better value per tool, but a smaller, focused kit ensures you only pay for the equipment you will actually use.

Specialized Tool Integration

While standard combo kits typically include drills and impact drivers, some applications require specialized equipment like the 2880-20 M18 Fuel brushless angle grinder. If your project involves metal fabrication, cutting, or surface grinding, verify if the combo kit includes the necessary tool or if you need to purchase it separately as a bare tool. The 2880-20 offers specific features like a no-lock paddle switch for safety and convenience. Always check the kit contents carefully to confirm that the specific power tools required for your primary tasks are included in the bundle before finalizing your purchase.

Kit Inclusions and Accessories

Beyond the power tools themselves, consider the included accessories. Kits like the 8-tool M18 set come with multiple batteries, chargers, and tool bags, which provide immediate utility. Accessories like high-capacity batteries significantly extend runtime, while durable storage bags keep your equipment organized and protected during transport. When comparing options, account for the total number of batteries included, as this can be a significant hidden cost. A kit that includes two or three batteries allows for continuous operation, as you can charge one while using the other, minimizing downtime during intensive work sessions.

Common questions

Frequently asked questions

What is the difference between the M18 and M12 combo kits?

The primary difference is the voltage platform. M18 tools are designed for high-power, heavy-duty applications, providing increased torque and sustained performance for large-scale projects. M12 subcompact tools are smaller, lighter, and optimized for portability, making them ideal for tasks in confined spaces or overhead work where weight is a concern. Choose M18 if your priority is raw power and M12 if your priority is ergonomics and mobility.

Does the 2880-20 grinder come in a combo kit?

Based on the provided product list, the 2880-20 M18 Fuel brushless angle grinder is listed as a 'Tool Only' item. It is not listed as a component of the M18 8-tool, 6-tool, or the 2-tool combo kits provided. If you require this specific grinder for your workshop, you will need to purchase it separately from your drill and impact driver combo kit.

Are all Milwaukee combo kits brushless?

No, not all kits are brushless. The 2892-22CT M18 compact kit and the M12 subcompact kit are explicitly identified as brushless. Other kits, such as the M18 6-tool 2696-26 set, do not specify brushless technology in their names. Brushless models generally offer higher efficiency and longevity, so check the specific product name for the 'brushless' designation if that feature is a requirement for your tool selection.

Which combo kit is best for a beginner building a workshop?

For a beginner, the M18 6-tool or 8-tool combo kits are strong options because they provide a wide variety of tools, batteries, and storage bags in one purchase. These larger kits cover the most common workshop needs, such as drilling, driving, and potentially cutting, without requiring individual tool purchases. Evaluate the specific tools included in the 8-tool set versus the 6-tool set to see which aligns best with your immediate project goals.

Can I use M18 batteries in an M12 tool?

No, Milwaukee M18 and M12 systems are not cross-compatible. M18 batteries are designed for the 18-volt platform, while M12 batteries are specific to the 12-volt subcompact tools. When selecting a combo kit, ensure your battery collection matches the voltage of the tools you are purchasing. If you intend to own both M12 and M18 tools, you must maintain separate battery and charger ecosystems for each platform.

Verdict

Bottom line

For users seeking the most robust performance for demanding tasks, the M18 platform is the clear leader. The 2892-22CT M18 Compact Brushless 2-Tool Combo Kit stands out as the strongest fit for most professional and serious DIY applications. By combining the high-torque output of the M18 system with the efficiency of brushless motors, this kit provides a reliable foundation for heavy drilling and fastening. While larger sets like the 8-tool or 6-tool M18 kits offer more variety, the 2-tool brushless combo offers the best balance of essential power, modern motor technology, and long-term durability. It is the most efficient choice for users who prioritize performance quality over the quantity of tools included in their initial purchase.

Deciding between these options depends on your workspace constraints and task intensity. If your work involves tight spaces or overhead fastening, prioritize the M12 Subcompact Brushless 2-Tool Kit for its superior handling and reduced weight. For those tasked with metalwork, select a standard drill/impact kit and supplement it with the 2880-20 Fuel angle grinder as a separate acquisition. If you are starting a workshop from scratch, the 8-tool M18 kit is the most logical choice, as it eliminates the need to source multiple batteries and chargers individually. Always match your kit choice to the specific voltage of the batteries you already own to ensure seamless integration into your existing tool collection.
