Bottom Line

The Milwaukee 3650-20 M18 Compact Impact Driver strikes a near-perfect balance between power, portability, and comfort, making it a great choice for both professionals and serious DIY enthusiasts who need a reliable tool for tight spaces and varied fastening needs. Just remember it’s sold as tool-only, so factor in the cost of batteries if you don’t yet own any M18 or M12 packs.
