The best Sawzall for most remodeling and demolition work is the Milwaukee M18 FUEL Super SAWZALL (2821-20): it combines a 1-1/4-inch stroke, up to 3,000 strokes per minute, and a tool-free blade clamp in a cordless design. For lighter jobs or a lower-cost battery-platform purchase, consider the DeWalt 20V MAX XR reciprocating saw (DCS382); for frequent corded work, the Milwaukee 15-amp Super SAWZALL (6538-21) avoids battery runtime limits.
“Sawzall” is Milwaukee’s brand name, but it’s often used informally for any reciprocating saw. The right sawzall tool depends less on the maximum speed printed on the box than on what you cut, how long you work, and whether the saw can reach the cut without fighting your hands or the surrounding material.

Compare the leading reciprocating saws
The figures below are manufacturer specifications for the listed tool configurations. Bare-tool weight excludes the battery; corded tool weight and included accessories can vary by package. A longer stroke generally removes material faster, but blade choice, pressure, and workpiece support matter too.
| Model | Power | Stroke and speed | Approx. bare-tool weight | Best fit |
|---|---|---|---|---|
| Milwaukee M18 FUEL Super SAWZALL 2821-20 | 18V battery | 1-1/4 in.; up to 3,000 SPM | About 7.4 lb | Heavy cordless demolition and remodeling |
| DeWalt 20V MAX XR DCS382 | 20V MAX battery | 1-1/8 in.; up to 3,000 SPM | About 5.8 lb | General remodeling and a lighter cordless setup |
| Makita 18V LXT XRJ05Z | 18V battery | 1-1/4 in.; up to 2,800 SPM | About 8.2 lb | Users already invested in Makita LXT batteries |
| Milwaukee 15-Amp Super SAWZALL 6538-21 | 15-amp corded | 1-1/4 in.; 0–2,800 SPM | About 9.8 lb | Long sessions near a reliable outlet |
Weight is only part of the handling picture. A battery adds weight, often at the handle end, while a cord can snag in a cluttered room. Anti-vibration features can make sustained cutting more comfortable, but they don’t eliminate vibration or make a heavy saw feel light. If possible, compare complete tool-and-battery setups rather than bare tools.
Choose by the work you actually do
For repeated, demanding demolition: Milwaukee M18 FUEL 2821-20
The 1-1/4-inch stroke and 3,000 SPM top speed suit fast rough cuts through framing lumber, nail-embedded wood, and demolition assemblies. Its adjustable shoe helps use different sections of a blade and control cutting depth. The trade-off is weight: this is a substantial saw, especially with a high-capacity battery. It makes most sense if you already own M18 batteries or expect to use it frequently enough to justify buying into the platform.
For remodeling with less weight in hand: DeWalt DCS382
The DCS382 is a practical choice for cutting pipe, opening wall sections, and occasional framing work. Its 1-1/8-inch stroke is shorter than the Milwaukee’s, but the difference in rated stroke length is not a guarantee that one will finish every cut faster: blade type, contact, and material can outweigh the spec. Pick it if its handling and your existing DeWalt 20V MAX battery collection make more sense for your projects.
For Makita LXT owners: Makita XRJ05Z
With a 1-1/4-inch stroke and a variable-speed trigger, the XRJ05Z offers a full-size option on Makita’s 18V LXT platform. The slower maximum speed than the Milwaukee 2821-20 is a modest paper-spec difference, not a verdict on cut quality. This is an easier purchase to recommend when you already have compatible batteries and chargers; buying a new battery platform for one saw can change the value calculation substantially.
For long cuts without battery swaps: Milwaukee 6538-21
This 15-amp corded model is built for sustained, demanding work. It avoids pauses to recharge or change batteries, which helps during a large demolition job near an outlet. Its weight and cord are real drawbacks in stairs, overhead work, and tight rooms. Use a suitable extension cord according to the tool manual and local electrical guidance; a corded saw is not a reason to work around standing water or damaged wiring.
What changes performance in wood, metal, and demolition?
- Wood and framing: Use a coarse wood-cutting blade for clean, fast cuts, or a demolition blade rated for nail-embedded lumber when hidden fasteners are likely. Keep the shoe against the work where practical; it stabilizes the saw and reduces blade flex.
- Metal pipe and conduit: Choose a metal-cutting blade with an appropriate tooth count. Support the material close to the cut so it cannot chatter, and start at a controlled speed. Thin sheet metal usually needs finer teeth than thick pipe.
- Flush cuts and limited reach: A flexible, longer blade can reach behind trim or cut close to a surface, but extra blade length also increases deflection. The compact saw may fit a tight gap better than a full-size high-power model; check the tool’s dimensions and blade clearance against the actual work area.
- Mixed demolition: Keep separate blades for wood, metal, and nail-embedded material. One worn blade used on everything is rarely the fastest or safest setup.
For overhead or extended-reach cuts, consider total tool weight, grip comfort, and access to a stable stance—not just the saw’s advertised cutting speed. Reciprocating saws are aggressive tools; secure the workpiece, wear eye and hearing protection, and check for wiring, plumbing, gas lines, and other hidden services before cutting into a wall.
Battery-platform and ownership costs
A bare cordless saw can look inexpensive until you add a battery and charger. If you already own compatible batteries, compare bare-tool prices; if not, compare complete kits. As a rough ownership example, a kit priced at $300 and used for 30 projects costs $10 per project before blades and other expenses. At 120 projects, that falls to $2.50 per project. This simple calculation explains why an occasional DIY user may get better value from a less expensive kit—or a corded saw—while a daily user may value a stronger platform and faster work more highly.
Blades are the main recurring consumable. Dull teeth cut slowly, generate more heat, and encourage users to push harder, which can increase blade flex and stress the tool. Replace a blade when it no longer cuts effectively; don’t wait for it to break. After dusty demolition, remove the battery or unplug the saw and clear debris from the shoe and accessible vents according to the manual. Avoid directing compressed air into areas where it could drive dust deeper into the tool.
Quick decision guide
| Your situation | Best direction | Why |
|---|---|---|
| Frequent heavy demolition; Milwaukee batteries already owned | Milwaukee M18 FUEL 2821-20 | Long stroke, high rated speed, cordless convenience |
| General remodeling; DeWalt batteries already owned | DeWalt DCS382 | Useful full-size capability with a comparatively lighter bare tool |
| Makita LXT batteries already owned | Makita XRJ05Z | Avoids buying into another battery system |
| Long work sessions near mains power | Milwaukee 6538-21 | No battery changes; accepts the cord and heavier body |
| Occasional cuts, limited storage, or tight access | Consider a compact reciprocating saw | Smaller tools are easier to store and maneuver, though often slower on heavy demolition |
Bottom line
The Milwaukee M18 FUEL 2821-20 is the strongest all-around pick here for demanding cordless demolition, while the DeWalt DCS382 is a sensible lighter choice for broad remodeling use. Makita owners should start with the XRJ05Z, and buyers with long, outlet-accessible jobs should consider the corded Milwaukee 6538-21. Match the saw to your battery platform, reach, and work frequency—and budget for the right blades, since they often determine the cut as much as the motor does.
