Milwaukee M18 FUEL SUPER SAWZALL (2722-20) review

A full-size M18 saw with a documented mode choice

The Milwaukee 2722-20 is the M18 FUEL SUPER SAWZALL in a bare-tool configuration. Its exact operator manual identifies an 18 V M18 tool, a brushless motor, a 1-1/4-inch stroke and a no-load range of 0 to 3,000 strokes per minute. The page and manual also describe a five-position speed dial alongside a variable-speed trigger. Together, those controls let the operator set a maximum speed and vary it at the trigger; they do not tell us how fast the saw will cut a particular pipe, stud or nail-embedded board.

The most consequential documented distinction is selectable orbital action. The manual explains how to choose straight reciprocation or move the control toward the orbital symbol, with intermediate positions available. Milwaukee describes orbital action as an option for aggressive cuts in wood and straight action for smoother cuts in metal. Treat those as maker guidance, not laboratory results. Blade choice, material, cut direction and secure work support still govern the cut.

Adjustments and blade handling

The shoe can move forward or backward using the release lever. The manual ties that adjustment to exposing a fresh section of blade or making a specialized cut and warns to check that the blade still extends beyond the shoe and work throughout the stroke. It also documents a QUIK-LOK clamp for tool-free changes and accepts 1/2-inch universal Sawzall blades. Milwaukee's manual says not to use blades shorter than 3-1/2 inches and to remove the battery before changing one. Check that the clamp retains the blade securely before starting.

The tool has an LED and a rafter hook listed in its documentation. These are practical details for seeing the immediate area and hanging the saw between cuts, but no claim about illumination coverage or storage capacity follows from their presence. The manual's setup instructions still matter: keep the shoe against the work, secure the material, use the correct blade, and check for hidden pipes or wiring before a blind or plunge cut. Wear the protection appropriate to the material, dust and site.

Milwaukee's official launch material gives the bare 2722-20 a weight of 8.8 pounds and separately gives 12.2 pounds with the HD12.0 battery. That distinction is useful when estimating a carry or overhead setup: the first is the bare tool, the second is a battery-on configuration. They are manufacturer-stated weights, not my measurements. The exact sources reviewed do not state the overall tool length.

Tool only is not the same as kit

The 2722-20 package is the bare saw. Milwaukee's separate 2722-21HD page lists a kit with the saw, one M18 REDLITHIUM HIGH OUTPUT HD12.0 battery, a rapid charger, a general-purpose blade and a contractor bag. Those contents belong to the kit suffix, not the -20. Confirm the full number and box list before comparing offers; product-page cross-sells or kit imagery are not proof of what the standalone SKU includes.

For an owner with compatible M18 batteries and a charger, the -20 avoids duplicating a package arrangement, but that does not guarantee the best value at any particular price. Someone building an M18 setup should compare the separate battery and charger requirements against the actual -21HD contents. I make no claim about current price, availability, runtime or battery life. Milwaukee's published performance language should not be mistaken for an independent test.

Who should shortlist it

The 2722-20 is an evidence-backed match when a buyer wants a full-size cordless M18 saw and specifically values documented orbital action and an adjustable shoe. Its known 8.8-pound bare-tool weight makes a weight ceiling easier to evaluate than it is for several models whose exact source material omits a tool-only figure. The battery-on weight is higher, so consider the complete setup rather than the bare tool alone when handling is the concern.

It is not the compact one-handed choice: that identity belongs to the 2625-20 HACKZALL. It is also different from the standard full-size 2621-20, whose exact sources do not establish orbital action, an adjustable shoe or a tool-only weight. Such comparisons reflect published feature evidence, not a side-by-side trial. This is a source-based assessment; I have not used, tested or measured the saw.
