How to choose
Voltage Selection
Milwaukee offers compact drilling solutions in both 12-volt and 18-volt platforms. The M12 line, including the 2598-22 hammer drill and impact kit or the 2401-22 screwdriver, focuses on lightweight portability for tight spaces and lighter-duty fastening. In contrast, the 18V options like the 3601-21P compact drill/driver kit and the 2691-22 combo kit provide higher voltage power, which is typically better suited for more demanding drilling tasks, larger fasteners, and professional-grade endurance. Choose 12V for maximum compactness or 18V when increased torque and sustained power output are required for your specific workshop projects.
Combo vs. Single Tool
Deciding between a single-tool kit and a combo kit depends on your project requirements. The 3601-21P is a dedicated 1/2-inch compact drill/driver kit, ideal for users who primarily need drilling and driving functionality with a single battery. Conversely, combo kits like the 2598-22 M12 Fuel 2-piece set or the 2691-22 18-volt set include both a drill and an impact driver. These combo kits are more versatile, allowing you to switch between drilling holes and driving fasteners without changing bits, which significantly improves efficiency during multi-step assembly or installation tasks.
Drill Bit Compatibility
To maximize the utility of any Milwaukee drill, pairing the tool with high-quality accessories is essential. The 48-89-2801 21-piece Thunderbolt Black Oxide drill bit set is designed for versatility across various materials. When selecting a drill set, ensure the bit shank size is compatible with your tool's chuck. Most compact drills feature 1/2-inch or 1/4-inch chucks. Using the correct bits ensures cleaner holes and better performance, preventing unnecessary wear on your drill motor. Always check that your bit set covers the range of diameters required for your specific fastening and drilling applications.
Brushless vs. Brushed Motors
Motor technology affects the efficiency and longevity of your power tools. The 3601-21P 18V kit features a brushless motor, which is engineered for improved efficiency compared to standard brushed models. Brushless motors generally offer a longer service life and better power management, which is beneficial for compact tools that rely on smaller battery capacities. While brushed motors found in other kits are reliable for standard tasks, brushless options are the preferred choice for users seeking advanced performance, reduced maintenance, and optimized battery run-time for frequent, repetitive drilling and driving operations.
Kit Inclusions
When purchasing a Milwaukee kit, pay close attention to the included components beyond the drill itself. Kits such as the 3601-21P, 2598-22, and 2691-22 typically bundle the tool with batteries, a charger, and a storage bag. This is a cost-effective way to enter a battery ecosystem. If you already own Milwaukee batteries, you might consider tool-only options, but for new users, these complete kits provide everything necessary to begin working immediately. Always verify the battery capacity—such as the 2.0 Ah battery included with the 3601-21P—to ensure it meets your runtime needs.
Frequently asked questions
What is the difference between the M12 and 18V Milwaukee drill kits?
The primary difference is the battery platform and power output. M12 kits, such as the 2598-22 or 2401-22, utilize 12-volt batteries, making them exceptionally compact and lightweight, perfect for tight areas. The 18V kits, like the 3601-21P or 2691-22, use a higher voltage system that generally provides more torque and power for heavier-duty drilling and driving applications. Choose M12 for portability and 18V for increased performance demands.
Do these Milwaukee kits include drill bits?
Most of the Milwaukee power tool kits listed, such as the 3601-21P, 2598-22, and 2691-22, do not include drill bits. These kits typically provide the power tool, batteries, a charger, and a storage bag. You will need to purchase bits separately to use with your new drill. The 48-89-2801 21-piece Thunderbolt Black Oxide drill bit set is an excellent standalone accessory kit to pair with these drills for various tasks.
Is the 3601-21P suitable for heavy-duty construction?
The 3601-21P is a 1/2-inch compact drill/driver kit designed for efficiency in smaller form factors. While it features an 18V brushless motor for reliable power, it is specifically categorized as a compact drill. It is well-suited for general drilling and driving tasks where space is limited. For extremely heavy-duty, industrial-grade construction, you may want to compare its specific torque specifications against larger, non-compact Milwaukee models to ensure it meets your professional requirements.
Can I use the same batteries for the 2598-22 and 2401-22 kits?
Yes, both the 2598-22 M12 Fuel kit and the 2401-22 M12 screwdriver kit belong to the Milwaukee M12 12-volt lithium-ion system. This means that any battery designed for the M12 platform is compatible with both tools. This cross-compatibility is a significant advantage, allowing you to share batteries between your drill, impact driver, and screwdriver, which helps minimize downtime and reduces the total number of batteries you need to maintain for your workshop.
What is the benefit of the 21-piece Thunderbolt bit set?
The 48-89-2801 Thunderbolt Black Oxide drill bit set provides a comprehensive range of 21 pieces, allowing you to handle a wide variety of hole sizes in different materials. Because these are not included in the power tool kits, purchasing this set ensures you have the necessary accessories to immediately start using your drill. The black oxide coating is designed for durability, making this a practical choice for keeping your workshop stocked with common drilling sizes.
Bottom line
For shoppers seeking the best Milwaukee compact drilling solution, the 3601-21P 18V Brushless Compact Drill/Driver Kit stands out as the strongest overall fit. By combining the efficiency of a brushless motor with the robust 18-volt platform, it offers a high power-to-size ratio that serves both professional and DIY needs effectively. While the M12 series, such as the 2598-22, excels in extreme portability, the 3601-21P provides a versatile middle ground with higher voltage capacity. When paired with the 48-89-2801 Thunderbolt bit set, it forms a comprehensive, ready-to-use setup. It is a reliable, modern choice for those prioritizing long-term motor performance and the power of the 18V battery ecosystem for standard workshop tasks.
Deciding between these options requires assessing your specific work environment. If your tasks involve confined spaces and light fastening, the M12 Fuel 2-piece kit (2598-22) is the superior, lightweight choice. However, if your work involves larger fasteners or drilling through tougher materials, the 18V options like the 2691-22 or the brushless 3601-21P are more appropriate. Always consider whether you need a standalone drill or a combo kit; a combo kit adds significant value for users who frequently switch between drilling and driving. Match your choice to the battery platform you already own to ensure maximum compatibility and long-term cost-effectiveness across your tool collection.
