The Milwaukee M18 SAWZALL Reciprocating Saw, Model 2621-20, is a cordless reciprocating saw built for demolition, rough cutting, and general jobsite tear-out. This is a reciprocating saw designed for demolition, remodel work, and cutting through wood, metal, and PVC. If you already run Milwaukee's M18 platform and need a proven saw that balances speed, durability, and control, this bare tool makes a lot of sense.

On the job, the numbers line up with what matters. The saw delivers up to 3,000 strokes per minute with a 1-1/8 inch stroke length, so it clears material fast in common demo work. That matters when you're cutting framing, old pipe, mixed material assemblies, or making repetitive rough cuts where slow stroke speed just wastes time. Milwaukee also calls out up to 30% faster cutting and 50% more run-time in key applications versus leading competitors, with REDLINK intelligence helping protect the tool from overload in hard-use conditions.

Milwaukee built this one around durability. The all-metal gearing and metal gear case are there for a reason: reciprocating saws get hammered in demolition, and weak drivetrains do not last. This saw is meant to handle repeated starts under load, dirty work areas, and the kind of use that comes with construction, remodeling, and service work. At 7.4 lbs bare, it has enough substance to feel planted without becoming a boat anchor in your hands.

Control is a big part of why this saw still has a following. The counterbalance mechanism reduces vibration, which helps with cut tracking and cuts down fatigue over a full day. That is especially useful when you're working overhead, reaching between studs, or cutting from awkward body positions where too much vibration makes the saw feel loose. The slim front-end design also helps the saw fit into tighter spaces and gives you a better view of the cut area.

Day-to-day usability is solid too. The lever-action QUIK-LOK blade clamp makes blade swaps quick, which is exactly what you want when moving from wood with nails to metal or PVC. Adjustable shoe support and keyless blade changes make it easier to manage blade life and keep the saw working efficiently as conditions change. Since this is a cordless saw, you also avoid dragging cords through demolition debris or fighting for outlet access in unfinished spaces.

The platform fit is straightforward. This model runs on the Milwaukee M18 battery system and is compatible with all M18 batteries and all M18 chargers. That makes it a strong buy for anyone already invested in M18 tools, because you can add a capable cordless demolition saw without paying again for batteries or a charger. It is sold as a tool-only configuration, so you will need to supply your own battery and charger.

As for who it is for, this is a good fit for remodelers, plumbers, HVAC techs, electricians, general contractors, and serious DIY users who need a dependable cordless SAWZALL for tear-out and rough cutting. It is not a trim or finish tool, and it is not pretending to be. It is built for the kind of work where speed, durability, and fast blade changes matter more than finesse.
