Specs: Stroke, Weight, and Kit

Stroke length

Edge: Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw

The Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw features a 1-1/4-inch stroke length. This longer stroke removes more material with each pass. The Milwaukee M18 Sawzall Kit 5.0 has a 1-1/8-inch stroke. A longer stroke generally increases cutting speed in thick materials. You get slightly more aggressive cutting action with the FUEL model. The difference is small but measurable. This spec matters most when you are cutting through dense lumber or metal. The FUEL model holds a clear advantage here for pure cutting volume per stroke.

Motor type

Edge: Tie

Both tools use a brushless motor. The Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw lists a brushless motor built for the M18 FUEL line. The Milwaukee M18 Sawzall Kit 5.0 also utilizes a brushless design with REDLINK Intelligence. Brushless motors offer better efficiency and longer life than brushed ones. They run cooler and provide more power. Since both share this core technology, there is no difference in motor type. You get similar performance characteristics from the drive system in both cases. This is a tie for basic motor technology.

Weight

Edge: Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw

Weight affects how you handle the tool during long cuts. The Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw weighs 8.8 pounds. The Milwaukee M18 Sawzall Kit 5.0 weighs 11.7 pounds. The significant weight difference comes from the included battery and charger in the kit. The bare tool weight of the FUEL model is much lighter. If you are working overhead or for extended periods, the lighter FUEL tool reduces fatigue. The kit version is heavier due to its complete package. The FUEL model wins for portability.

Battery capacity

Edge: Milwaukee M18 Sawzall Kit with 5.0 Ah Battery

Battery capacity determines run time. The Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw is sold as a bare tool. It does not include a battery. The Milwaukee M18 Sawzall Kit 5.0 includes an M18 REDLITHIUM XC 5.0 Battery. This 5.0Ah battery provides substantial power. The FUEL model can accept the same high-capacity batteries from the M18 system. However, the kit offers immediate readiness with a large battery. If you already own batteries, the bare tool is fine. For new users, the kit provides the necessary power source. The kit wins for completeness.

Blade clamp type

Edge: Tie

Blade changes are frequent in demolition work. The Milwaukee M18 FUEL 1-1/4-Inch Reciprocating Saw uses a toolless blade clamp. This allows for quick changes without extra tools. The Milwaukee M18 Sawzall Kit 5.0 features a Lever Action QUIK-LOK blade clamp. Both systems allow fast blade swaps. The toolless design on the FUEL model is straightforward. The lever action on the Sawzall is also designed for speed. Both methods are effective for changing blades quickly on the jobsite. Neither system has a clear superiority in ease of use. This is a tie for convenience.
