No. Not designed for that.
This tool is for drilling and driving screws. Using it for mixing can cause permanent damage from continuous overloading. The high torque can strip gears or burn out the motor. Only use accessories specifically recommended by Milwaukee for this tool. Mixing paddles are not listed.
If you need to mix, use a tool rated for that purpose, like a dedicated mixer.
Heads up: Overloading voids the warranty. Have the tool serviced only by a qualified repair person using identical replacement parts.
