How to choose
Voltage Platform Selection
When choosing a Milwaukee compact drill, identify whether the M12 or 18V platform best suits your workflow. The M12 line, including the 2505-22 Installation Drill/Driver and 2401-22 Screwdriver, prioritizes portability and lightweight handling for tight spaces. Conversely, the 18V options like the 3601-21P and 2691-22 combo kit provide higher voltage for demanding drilling and driving tasks. Consider your existing battery inventory to maintain ecosystem compatibility, as 12V and 18V batteries are not interchangeable. Matching the tool to the specific power requirements of your projects ensures efficient operation without unnecessary weight, allowing for better control during extended use in workshop or installation environments.
Drill vs. Driver Functionality
Distinguish between drill/drivers and impact drivers based on your primary tasks. A drill/driver like the 3601-21P or 2505-22 offers versatility for drilling holes and driving screws with adjustable clutch settings. In contrast, tools like the 3453-20 12V Fuel Hex Impact Driver are engineered specifically for high-torque fastening applications where speed and rotational force are essential. If you frequently switch between drilling and driving, a combo kit such as the 2691-22 provides both tools in one package. Select a dedicated driver if your workflow consists primarily of heavy-duty fastening, or a drill/driver if you require the flexibility to perform both drilling and driving operations.
Brushless vs. Brushed Motors
Milwaukee power tools utilize either brushless or brushed motor technology, which impacts long-term efficiency and performance. Brushless models, such as the 3601-21P and 3453-20, are designed for enhanced operational efficiency compared to traditional brushed counterparts. While brushed tools like the 2691-22 remain functional staples for various tasks, brushless versions are typically marketed as part of the 'Fuel' or advanced compact lines to provide optimized power delivery. When choosing a tool, evaluate the motor type if you prioritize longevity and consistent torque under load. Always verify the specific model specifications to confirm if the tool utilizes brushless technology for your intended heavy-duty or precision applications.
Chuck and Hex Compatibility
The interface for bit retention varies across the Milwaukee compact range and significantly affects tool utility. Models featuring a 1/2-inch chuck, such as the 3601-21P, accommodate a wide range of standard drill bits for general construction work. Conversely, 1/4-inch hex drives found on the 2401-22 and 3453-20 are optimized for rapid, secure bit changes during driving tasks. The 2505-22 Installation Drill/Driver offers specific versatility for unique installation needs. Assess the type of fasteners and bits you use most frequently to determine if a chuck-based drill or a hex-drive system better aligns with your toolkit requirements and typical daily tasks.
Kit Inclusions and Bare Tools
Evaluate whether a complete kit or a bare tool is more practical for your needs. Kits like the 3601-21P, 2505-22, 2401-22, and 2691-22 include essential components such as batteries, chargers, and carrying bags, providing a ready-to-use solution for those starting a new platform. If you already own compatible Milwaukee batteries and chargers, purchasing a bare tool like the 3453-20 allows you to expand your capabilities without the added cost of redundant accessories. Review the specific kit contents listed for each model to ensure you have the necessary power source and storage solutions to maintain your equipment effectively and keep your workspace organized.
Frequently asked questions
What is the primary difference between the 3601-21P and the 2691-22?
The 3601-21P is a modern 18V brushless compact drill/driver kit that includes a 2.0 Ah battery, charger, and bag. It focuses on single-tool utility with advanced motor technology.

Can I use M12 batteries with the 18-volt compact drills?
No, M12 batteries are not compatible with 18-volt tools. The M12 line, including the 2505-22, 2401-22, and 3453-20, operates on a 12-volt platform. The 3601-21P and 2691-22 require 18-volt batteries. Always ensure you are using the correct battery voltage for your specific tool model to prevent damage and ensure the tool operates correctly according to the manufacturer's design specifications for power delivery.
Is the 3453-20 suitable for drilling holes?
The 3453-20 is a 12V Fuel 1/4" Cordless Hex Impact Driver. Impact drivers are specifically engineered for driving fasteners and screws with high torque. While they excel at driving, they are not designed for general-purpose drilling like a 1/2-inch drill/driver. If your primary goal is drilling holes, you should consider a drill/driver model such as the 3601-21P or the 2505-22 Installation Drill/Driver.
Which tool is best for tight spaces?
The M12 line is generally the best choice for tight spaces due to the compact nature of the 12-volt battery platform and tool design. The 2505-22 M12 Fuel Installation Drill/Driver and the 2401-22 M12 1/4" Hex Cordless Screwdriver are specifically designed to be compact and maneuverable. These tools allow for better access in confined areas where larger 18-volt drill/drivers might be too bulky to operate effectively.
Does the 2505-22 kit come with a battery?
Yes, the 2505-22 M12 Fuel Installation Drill/Driver Kit includes the necessary components to get started, as it is sold as a kit. While the product name confirms it is a kit, always verify the specific package contents provided by the retailer at the time of purchase to ensure it includes the battery and charger, as these items are essential for the operation of the M12 tool platform.
Bottom line
For users seeking the most versatile and modern solution, the Milwaukee 3601-21P 18V Brushless Compact Drill/Driver Kit stands out as the strongest fit. Its brushless motor technology offers efficient performance for general drilling and driving, while the inclusion of a 2.0 Ah battery and charger makes it an excellent entry point for the 18V ecosystem. If your work involves a mix of heavy-duty construction and standard fastening, this model provides the necessary power and reliability. For those needing specialized, ultra-compact access, the 2505-22 M12 Fuel Installation Drill/Driver is the superior choice, offering unique maneuverability for professional installation tasks without sacrificing the durability expected from the Fuel line.
Deciding between these models requires evaluating your specific power and space constraints. Choose an 18V kit like the 3601-21P or 2691-22 if your priority is high-torque drilling and compatibility with a larger battery platform. Opt for M12 tools like the 2505-22, 2401-22, or 3453-20 if your workflow centers on portability, precision, and working in confined areas. If you already own compatible Milwaukee batteries, selecting a bare tool like the 3453-20 is the most cost-effective path. Ultimately, align your purchase with your existing battery inventory and the specific demands of your most frequent workshop or onsite projects to ensure maximum utility.
