Frequently asked questions
What is the difference between the 2505-22 and the 2504-21 kits?
The 2505-22 is an M12 FUEL Installation Drill/Driver designed specifically for compact, awkward spaces. In contrast, the 2504-21 is an M12 FUEL CP Brushless 1/2-inch Hammer Drill Driver. While the installation driver focuses on versatility in tight quarters, the hammer drill is engineered for more demanding drilling applications, including masonry. Your choice should depend on whether you prioritize extreme compactness for cabinet or assembly work or the raw drilling power required for tougher construction materials.
Can I use my existing M12 batteries with these kits?
Yes, all M12 drill driver kits and bare tools are compatible with the Milwaukee M12 12-volt lithium-ion battery platform. Whether you purchase a comprehensive kit that includes batteries, such as the 2504-21, or a bare tool like the M12 Subcompact Brushless Impact Driver, your existing M12 batteries will power the units. This cross-compatibility is a primary benefit of the M12 ecosystem, allowing you to expand your tool collection without needing to purchase new power cells for every individual unit.
Does the 2-tool combo kit include a battery?
Yes, the M12 12-Volt Cordless Drill Driver/Impact Driver Combo Kit (2-Tool) includes an additional 2-pack of 1.5Ah batteries. This configuration is beneficial for users who require extended runtime, as it allows you to rotate batteries while one is charging.
