Milwaukee 3403-22 M12 FUEL Drill/Driver Kit vs Milwaukee M18 FUEL Hammer Drill 2804-20

Buy the M12 FUEL 3403-22 if you want a compact kit you can carry all day and use in tight spots; it comes with two batteries, a charger and a bag, and owners rate it 4.8/5. Buy the M18 FUEL 2804-20 if you drill masonry, bore large holes or drive long screws; its hammer mode and 1,200 in-lbs of torque do work the M12 cannot. The M12 is lighter and shorter, the M18 is stronger and has a hammer function, and both use brushless motors and all-metal chucks.

• Choose the M12 FUEL 3403-22 if you want a light, short drill for cabinet work, assembly and overhead jobs, and you want batteries and a charger in the box.
• Choose the M18 FUEL 2804-20 if you drill into brick or concrete, use hole saws and auger bits, or already own M18 batteries.
