In contrast, the Milwaukee M18 9-tool combo kit boasts a comprehensive selection of nine different tools, providing a much broader range of capabilities. This means that while the M12 kit is suitable for specific tasks, the M18 kit is better suited for users who need multiple tools for various projects. The M18 kit's extensive variety may justify its higher price, depending on your needs.
Battery and Power
Battery performance is a critical factor in cordless tools. The M12 FUEL kit includes two batteries: a 2.0 Ah compact battery and a 4.0 Ah extended capacity battery. However, the M18 combo kit takes the lead with three 4.0 Ah high-capacity batteries, allowing for longer usage periods without needing a recharge.

The impact driver in the M12 kit operates at 3,300 RPM, allowing for quick fastening. On the other hand, while the M18 kit does not specify the RPM for all its tools, it is designed for professional-grade performance across a wider variety of applications. Users requiring high power and versatility may find the M18 kit more beneficial.
Portability and Storage
The Milwaukee M12 FUEL kit is lightweight and compact, designed specifically for easy handling in tight spaces. Weighing only 2.8 lbs, it excels in portability. Meanwhile, the M18 kit includes a durable tool bag for organized storage of its nine tools and accessories. This added feature is beneficial for transporting multiple tools to job sites.
