Milwaukee M12 Fuel Hammer Drill & Impact Kit vs Milwaukee M18 Fuel Drill and Impact Driver Combo

Buy the M12 combo for tight spaces, overhead work and lighter everyday jobs; it is the most compact drill and impact driver in its class and the 12V FUEL tools punch above their size. Buy the M18 combo if you drill into brick, block or concrete, drive long screws all day, or want one platform that covers heavy work. The M18 is bigger and heavier in the hand but has far more torque and a deeper tool lineup; the M12 is easier to carry and control. Owners of both rate the build and triggers highly, and the M12's 4.8 rating from over 3,200 buyers reflects that.

• Choose the M12 combo if you work in cabinets, tight framing, electrical or overhead jobs and want the smallest, lightest kit that still drills and drives hard.
• Choose the M18 combo if you drill masonry, run large bits and long fasteners, or want headroom for heavier tools on the same batteries.
