Milwaukee M18 FUEL Hackzall vs Milwaukee M12 Fuel 1/2-Inch Drill/Driver

These are different tools, not rivals. The Hackzall is a one-handed reciprocating saw for cutting metal, PVC, wood and roots in tight or overhead spots. The M12 Fuel drill/driver is a compact 12V drill for drilling and driving. Buy the Hackzall if you need to cut; buy the M12 drill if you need holes and fasteners. Owners praise both for power and compact size, but each has durability complaints: Hackzall users report saws dying, and M12 users report a plastic trigger breaking and cut-offs overhead.

• Choose the Milwaukee M18 FUEL Hackzall if you already own M18 batteries and need one-handed cutting of metal, pipe, PVC or branches in tight spaces.
• Choose the Milwaukee M12 Fuel drill/driver if you want a short, light 12V drill for driving screws and drilling small holes in cabinets, fixtures and tight corners.
