The Milwaukee M18 FUEL SAWZALL Reciprocating Saw is a full-size cordless reciprocating saw built for demanding demolition, remodel, and rough-in work. Milwaukee rates it at up to 3,000 strokes per minute with a 1.25 in. stroke length, using a POWERSTATE Brushless motor for faster material removal under load. This tool-only version is compatible with the M18 FUEL battery platform and adds practical jobsite features like an adjustable shoe, LED work light, and hanging hook. It fits buyers who already own M18 batteries and want Milwaukee's current-generation standard SAWZALL without stepping up to the larger Super SAWZALL.
Does the 2821-20 include a battery or charger?
No. The 2821-20 is a bare-tool package with the saw only, so M18 batteries and a charger are sold separately.
What is the stroke speed of the 2821-20?
Milwaukee lists the saw at up to 3,000 strokes per minute. Combined with the 1.25 in. stroke length, that puts it in the heavy-duty full-size class for fast material removal.
What blade clamp does the 2821-20 use?
It uses a lever-action QUIK-LOK universal blade clamp. That setup is intended to make blade changes faster on the job without added tools.
Is this the ONE-KEY version?
No. The 2821-20 is the standard version without ONE-KEY. Buyers who want tracking and digital tool-management features should look at the 2822-20.
How large is the 2821-20?
Milwaukee lists it at 17.1 in. long, 6.3 in. high, 3.6 in. wide, and 6.8 lb excluding the battery. That makes it a full-size two-handed reciprocating saw rather than a compact one-handed model.
Who is the 2821-20 best for?
It is best for users already on the M18 platform who want Milwaukee's current-generation standard SAWZALL for demolition, framing cutouts, rough plumbing, and general jobsite cutting.
