Buying guide

How to choose

Voltage Platform

Selecting the right voltage is the primary step when choosing a Milwaukee compact drill. The M12 series offers subcompact portability, ideal for tight spaces and lighter-duty tasks. In contrast, the M18 platform provides increased power for more demanding applications. Consider whether your existing battery ecosystem requires 12V or 18V compatibility, as these systems are generally not interchangeable. Choosing a platform that aligns with your current tool collection ensures you always have a charged battery ready for work. Always verify if the kit includes the necessary multi-voltage charger to support your selected tools, especially when moving between different battery power levels within the Milwaukee brand lineup.

Brushless Motor Technology

Brushless motor technology is a critical feature for efficiency and longevity. Models like the 2798-22CT and the M12/M18 subcompact/compact brushless drill/drivers utilize this design to optimize energy consumption during operation. Brushless tools typically offer a more compact form factor compared to brushed counterparts, making them easier to maneuver in cramped workshop environments. When selecting a kit, prioritize brushless options to ensure consistent performance over the life of the tool. This technology is particularly beneficial for professionals who rely on their drills for extended periods, as it helps manage heat buildup and reduces the frequency of battery changes during heavy-duty projects.

Combo Kit vs. Bare Tool

Deciding between a combo kit and a bare tool depends on your current equipment inventory. Combo kits, such as the 2798-22CT or the M12 subcompact 2-tool kit, provide a comprehensive starting point by including the drill, impact driver, batteries, and a charger. These kits often arrive with a contractor bag for storage and transport. If you already own compatible Milwaukee batteries, purchasing a bare tool like the M18 compact brushless 1/2 inch drill/driver may be more cost-effective. Evaluate whether you need an impact driver alongside your drill, as combo kits frequently offer better value for those needing a complete fastening and drilling solution.

Drill Chuck Capacity

The chuck size determines the range of drill bits and accessories your tool can accommodate. The M18 compact brushless drill/driver features a 1/2-inch chuck, which is standard for heavy-duty drilling and driving tasks that require larger bit shanks. The M12 subcompact 3/8-inch drill/driver is designed for smaller bits, emphasizing a lightweight and agile profile. Assess the diameter of the bits you use most frequently; a 1/2-inch chuck provides greater versatility for various construction and repair jobs. Ensure that your choice matches the requirements of your specific projects, as the chuck size significantly influences the drill's overall capability and compatibility with various job site accessories.

Portability and Ergonomics

Compact drills are engineered for superior handling in restricted areas. The M12 subcompact line is specifically marketed for its small footprint, making it an excellent choice for overhead work or jobs inside cabinetry. The M18 compact series balances increased power with a design intended for mobility. Look for features like included belt clips, which enhance convenience by keeping the tool accessible while you move around the job site. The weight and balance of the tool impact user fatigue over long sessions. Evaluate the dimensions provided for the specific model to ensure it fits comfortably in your hand and reaches the tight corners of your workspace.

Common questions

Frequently asked questions

What is the primary difference between M12 and M18 Milwaukee drills?

The primary difference lies in the power platform and physical size. The M12 series represents Milwaukee's subcompact category, optimized for portability and tight-space maneuverability using 12V batteries. The M18 line utilizes 18V batteries, offering a more robust power output suitable for larger, more demanding drilling and fastening tasks. Choosing between them depends on whether your priority is maximizing lightweight handling for smaller projects or increasing torque and capacity for heavy-duty construction requirements.

Does the 2798-22CT kit include everything needed to start working?

Yes, the 2798-22CT is a comprehensive 2-tool combo kit. It includes the brushless drill, a brushless impact driver, two 18V 1.5Ah Li-Ion batteries, and a multi-voltage 12-18V charger. Additionally, the kit comes with a belt clip for each tool and a contractor bag for organized storage and transport. This set is designed to provide a complete fastening and drilling solution immediately upon arrival, assuming you have the necessary drill bits and driving accessories for your specific application.

Are brushless motors better than the motors found in the 2691-22 kit?

Brushless motors are generally considered more efficient and durable than traditional brushed motors. While the 2691-22 18-Volt kit is a highly-rated option, newer models like the M18 compact brushless drill/driver utilize brushless technology to reduce friction and heat buildup during use. This often results in longer tool life and improved battery efficiency. If your work involves frequent, heavy-duty use, choosing a brushless model may provide better long-term reliability and performance consistency compared to standard brushed motor designs.

Can I use M12 batteries with the M18 compact brushless drill?

No, M12 batteries are not compatible with M18 tools. The M12 and M18 platforms operate on different voltage systems. You must use M18-branded batteries with any tool in the M18 compact brushless line. Similarly, the M12 subcompact tools require M12 batteries to function. Always check the battery voltage requirements listed for your specific drill to ensure you have the correct power source, as attempting to use incompatible batteries can result in a failure to operate or potential damage.

Which drill is best for working in very tight, cramped spaces?

For extremely tight spaces, the M12 subcompact brushless 3/8-inch drill/driver is an excellent choice. Its subcompact design is specifically engineered for maximum maneuverability where larger tools would be cumbersome. If you need a combo kit that maintains this small profile, the M12 subcompact 2-tool combo kit offers both a drill and an impact driver in a compact form factor, allowing for effective fastening and drilling in restricted areas without sacrificing the convenience of the lightweight M12 battery system.

Verdict

Bottom line

For those prioritizing a balance of power and portability, the M18 series remains the gold standard in the Milwaukee lineup. The 2798-22CT combo kit stands out as the most versatile choice, offering both a brushless drill and an impact driver, which covers the vast majority of workshop needs. Its inclusion of a multi-voltage charger and two batteries makes it a high-value package for users entering the 18V ecosystem. If your work involves heavy-duty construction or frequent fastening, the M18 compact brushless 1/2 inch drill/driver provides the necessary torque and chuck capacity to handle demanding materials. It is the strongest fit for professionals who require a reliable, high-performance tool that stands up to rigorous daily use.

Deciding between these options requires an honest assessment of your power needs versus space constraints. If you work primarily in overhead, tight, or indoor spaces, prioritize the M12 subcompact brushless line for its superior agility and lighter weight. Conversely, if you are tackling structural framing, large-diameter drilling, or heavy-duty driving, the M18 platform is mandatory. Always check if you possess existing batteries, as this can make the difference between needing a full combo kit or just a bare tool. Select the M12 for finesse and mobility, or the M18 for sheer torque and heavy-duty endurance to ensure your tool kit matches your specific project demands.
