This winter, I purchased a M18 Fuel (2804) hammer drill, a Clam Plate and new blades to use with my 8" Strike Master Lazer. I do not have the drill set to hammer mode.
I couldn't be more happy with the performance of that setup. It went through 18" of ice in less then 10 seconds.
If the mud mixer has similar torque, then I would expect you won't have any problems either.
I do plan to add a spring mod to the Clam Plate for the trigger just for convenience.
