“It doesn't matter, it's just a hole”
Are you referring to arguing about augers or high school girlfriends.
Ridgid, Ryobi, and Makita all make a 750# drill so it’s not just DeWalt and Milwaukee. Pretty sure a few others are making them that big as well.
My understanding is that the benefit of a KDrill is that it can reopen old holes better due to it having a chipper blade.
Also, on the torque needed to turn an auger, my 750# drill grunts more when paired with a Lazer bit than it does when it’s paired with a mora style bit. Both bits being the same size. The Lazer has more aggressive blades than the flat blades on a mora but regardless of that, if your blades aren’t sharp it doesn’t matter what kind you have.
