Dewalt 20V vs Milwaukee 12V power tools for trimming horses’ hooves

I love using my Dewalt 20 V brushless paddle switch angle grinder and 20 V cut out tool to trim horses feet, particularly when they are rockhard. These tools really get the job done. They are powerful and reliable. They are also heavy, somewhat difficult to manage, especially if you have small hands, and noisy. Recently I came across the Milwaukee 12 V 2” right angle and straight die grinder. I was intrigued because they are variable speed, lighter and smaller, and much quieter, so I decided to compare them and see how they do.
