Milwaukee M18 FUEL 1/2" Drill/Driver Kit vs Milwaukee M18 Compact Brushless Drill Driver

Buy the 2903-22 if you drill big holes in dense wood, drive long lags, or want one drill that does the heavy work. Buy the 3601-21CT if you work overhead, in cabinets, or in tight framing and want a light tool that still has brushless power. The 2903-22 wins on torque, battery capacity and kit contents; the 3601-21CT wins on size and weight. Both are M18 FUEL-era brushless tools with metal chucks and 5-year tool warranties, and owners of both lines report them as durable daily drivers.

• Choose the 2903-22 if you need maximum torque for large self-feed bits, hole saws and lag screws, and want two 5.0 Ah batteries in the kit.
• Choose the 3601-21CT if you mostly drill and drive in tight or overhead spaces and want the lightest, shortest M18 drill.
