I've just purchased one of these mini drills out of China for drilling wee holes in printed circuit boards. Freehand drilling with a Dremel to do this gets old very fast I can tell you
I've also discovered that tiny tungsten carbide drill bits are easy to find at a cheap price from China as well. When I was still doing a lot of model making buying tiny drills at model shop prices was expensive. The Chinese are basically selling their drills for 1/10th the price and they're tungsten carbide and not HSS which is a major bonus
Money can't buy happiness, but it can buy chocolate which is almost the same thing
