Great work and a reminder that the drills in this class (high amp, very low revs) are still powerhouses. They develop so much torque that they can actually be dangerous if used without some care. They’re sometimes called widowmakers because if a spade bit or hole saw binds up the drill will counter-rotate and can throw someone off a ladder or roof. I broke some bones in my right hand years ago using one of these drills with a large hole saw. I was working on the soffits on a two-story house at the top of a ladder and consider myself pretty lucky that it wasn’t injured more seriously.
