Milwaukee® 2722-20 Super Sawzall® Review
One reviewer described the 2722-20 Super Sawzall® as the most powerful reciprocating saw they had used, highlighting how quickly it cut through a heavily rusted bolt.

One user highlighted the 2821-20 M18™ FUEL™ Sawzall® for its strong cutting performance, saying it quickly removed small tree stumps when paired with an aggressive pruning blade and was capable of tackling larger stumps as well.
