A dwelling drill is one you are not applying enough pressure to in order to get it to bite. It will sit and grind (hone) itself until the tip is a round slag ball if you keep at it long enough. Even with good coolant, you have to keep steady presser on the bit.
I use cutting oil for coolant, with out it I will always burn up the tip on a drill long before I will with it. The drill press I am using is a 16 speed floor standing one and set on the lowest speed always. I use Marvel Mystery Oil and apply a squirt at the start then at the first hint of smoking afterwards.
