Both tools are designed for heavy-duty tasks, but they serve different purposes and feature distinct designs. The 2864-20 is geared towards maximum torque and power, while the 2564-20 is designed for tight spaces and ease of use.
Design and Build Quality
The Milwaukee 2864-20 Fuel One-Key stands out with its robust and compact design, measuring just 8.59 inches in length, making it the most compact cordless high torque impact wrench in its class. In contrast, the Milwaukee 2564-20 Right Angle Impact Wrench features a unique 90-degree angle design, which allows it to fit into confined spaces where traditional wrenches may struggle.

Both tools are constructed with durability in mind, ensuring long-lasting performance.
Power and Performance
The Milwaukee 2864-20 Fuel One-Key excels in power, delivering up to 1200 ft-lbs of fastening torque and an impressive 1500 ft-lbs of nut-busting torque. This makes it an excellent choice for demanding applications where high torque is essential. On the other hand, the Milwaukee 2564-20 offers 220 ft-lbs of torque, which is sufficient for many heavy-duty tasks but not nearly as powerful as the 2864-20. If maximum torque is a priority, the 2864-20 clearly outperforms the 2564-20 in this category.
Battery and Runtime
The Milwaukee 2864-20 is powered by the M18 FUEL Lithium-Ion battery, which is known for its high efficiency and long runtime. This model also features One-Key technology, allowing users to customize and track tool performance. The Milwaukee 2564-20, however, runs on the M12 FUEL Lithium-Ion battery, designed for smaller tools but still providing reliable power. While both tools are battery-operated, the choice of battery impacts their overall runtime and suitability for different tasks. The 2864-20's battery allows for greater power, while the 2564-20’s battery is optimized for compactness and convenience.
Price Comparison
The Milwaukee 2864-20 is priced at $319.99, which is significantly more than the Milwaukee 2564-20's price of $176.98.

This price difference can influence purchasing decisions, especially for DIYers or professionals who may not need the added torque that the 2864-20 provides.
Applications and Usability
The Milwaukee 2864-20 is ideal for heavy-duty applications where high torque is necessary, such as automotive repairs or industrial settings. Its power and features make it suitable for professional use where performance is critical. Conversely, the Milwaukee 2564-20 is perfect for tasks in tight spaces, such as plumbing or electrical work, due to its right angle design. The lightweight and compact nature of the 2564-20 makes it user-friendly for those who need a reliable tool for less intense applications.
