How to choose
Compatibility and Replacement Parts
When maintaining your Milwaukee tools, verify part numbers specifically for your model. The 42-66-1006 and 42-66-2706 parts are designed for specific drills like the 2704-20 and 2704-22. Always confirm that your specific tool series is listed before purchasing chuck replacements or mounting screws to ensure proper fitment. Using components explicitly compatible with your model prevents mechanical issues during operation.
Tool Kits vs. Bare Tools
Decide whether you need a comprehensive setup like the 2697-22 combo kit, which provides both a hammer drill and an impact driver, or a specialized bare tool. Bare tools, such as the 2621-20 Sawzall or M18 FUEL die grinder, are ideal if you already own compatible M18 or M12 battery systems. Evaluate if your current workshop needs a multi-tool set or a specific application-focused device.
Voltage Platform Selection
Milwaukee tools operate on distinct battery platforms. The M18 line, including the 2621-20 reciprocating saw and 2697-22 combo kit, offers high-voltage power for heavy-duty tasks. Conversely, the M12 FUEL line, such as the 2486-20 in-line die grinder, focuses on compact, portable performance. Match your new tool to your existing battery inventory to avoid unnecessary additional investments in chargers or power packs.
Specialized Application Features
Assess the specific mechanical features required for your work. If you require precision grinding, the M18 FUEL die grinder with ONE-KEY or the M12 FUEL in-line version provides distinct advantages. For demolition, the 2621-20 Sawzall offers a Quik Lok blade clamp and an all-metal gearbox. Prioritize features like variable speed, braking capabilities, or specific chuck capacities based on the materials and tasks you encounter most frequently.
Durability and Build Quality
Look for construction details that signal longevity, such as all-metal gearboxes found in the 2621-20 reciprocating saw. When purchasing replacement parts like chucks, ensure they support the necessary clamping capacity—typically 1/16" to 1/2" for standard drill models like the 2704-22. Durable components and compatible hardware are essential for maintaining the operational life of high-performance tools under regular workshop usage.
Frequently asked questions
Can I use the 42-66-1006 chuck on my 2704-22 drill?
Yes, the 42-66-1006 and 42-66-2706 parts are specifically listed as compatible replacements for the Milwaukee 2704-22 drill model. These parts feature a 1/16"-1/2" clamping capacity and a 9/16"-18 mount, including the necessary 05-88-0019 screw. Always verify your specific drill's model number against these provided specifications to ensure the part is the correct fit before installation.
Does the 2697-22 combo kit include batteries?
The 2697-22 M18 18-Volt Lithium-Ion Cordless Hammer Drill/Impact Driver kit is a two-tool combo set. While the product name identifies it as an XC combo kit, you should always check the specific retailer packaging details at the time of purchase to confirm if batteries and chargers are included, as some kit configurations may vary based on the specific SKU provided by the manufacturer.
What is the difference between the M18 and M12 die grinders?
The primary difference lies in the battery platform and tool design. The M18 FUEL die grinder is a variable speed, paddle switch model designed for the M18 battery system, whereas the 2486-20 M12 FUEL die grinder is an in-line tool designed for the M12 platform. Your choice depends on your existing battery inventory and whether you prefer the power of the M18 platform or the compact nature of the M12.
Does the 2621-20 Sawzall come with a battery or charger?
The 2621-20 M18 18V Lithium Ion Cordless Sawzall is explicitly labeled as a 'Bare Tool.' This means it does not include a battery or a charger in the package. It is intended for users who already possess compatible Milwaukee M18 batteries and chargers. Ensure you have the necessary power equipment on hand before purchasing this specific model for your workshop.
What is the clamping capacity of the replacement chuck for the 2704-22?
The replacement chuck parts compatible with the Milwaukee 2704-22 model, specifically the 42-66-1006 and 42-66-2706 components, provide a clamping capacity ranging from 1/16" to 1/2". These parts also feature a 9/16"-18 mount and come with the required 05-88-0019 screw for installation. This capacity is designed to accommodate a wide variety of standard drill bits used with the 2704 series drills.
Bottom line
For users specifically targeting the Milwaukee 2704-22, the most relevant product is the 42-66-1006 replacement chuck. It serves as a vital component for those looking to maintain their drill’s clamping integrity, supporting the 1/16"-1/2" capacity required for high-performance drilling. If your goal is expanding your tool collection, the 2697-22 combo kit remains the strongest fit for comprehensive drilling and driving needs. For specialized tasks, the M18 FUEL die grinder and 2621-20 Sawzall offer professional-grade durability with features like all-metal gearboxes and Quik Lok blade clamps. Choosing between these depends on whether your priority is current tool maintenance or upgrading your workshop capability with specific, application-driven power tools.
Deciding between these options requires assessing your current tool inventory and immediate workshop requirements. If you own a 2704-22 and it requires chuck maintenance, prioritize the compatible replacement parts. Conversely, if you are looking to start or expand an M18 system, the 2697-22 combo kit provides the best value by bundling two essential tools. For specialized metalworking or demolition, select the bare tools—such as the die grinders or Sawzall—that align with the battery platform you already own. Always confirm your battery system and tool model number before finalizing your choice to ensure full compatibility.
