## Bottom Line

The Milwaukee 2721-20 M18 FUEL SAWZALL combines professional-grade power, smart connectivity, and cordless convenience, making it a top candidate for pros needing a versatile, battery-powered saw. However, if you’re concerned about blade retention or will be cutting for long periods, keep the weight and blade holder issues in mind.

If you want similar power without the blade holder concern, you might also want to explore alternative M18 FUEL reciprocating saw models as they may offer different blade holder designs.
