Milwaukee M12 FUEL 2-Tool Combo Kit vs Milwaukee M18 FUEL Hackzall

These are different tools, not rivals. The M12 FUEL 3497-22 is a two-tool drill and impact driver kit for driving screws, drilling and light hammer drilling; the M18 FUEL Hackzall is a one-handed reciprocating saw for cutting metal, wood, PVC and pipe. Buy the kit if you need fastening and drilling and want batteries and a charger in the box. Buy the Hackzall if you already own M18 batteries and need to cut. On build, owners rate the M12 kit highly for compact power and value, while Hackzall owners praise smooth, low-vibration one-handed cutting but some report durability problems when pushed hard.

• Choose the M12 FUEL 3497-22 if you want one compact kit that drills, drives and hammer-drills, with two batteries and a charger included.
• Choose the M18 FUEL Hackzall if you already run M18 batteries and need one-handed cutting in metal, wood or pipe, especially overhead or in tight spots.
