I do some work at miniature scale (dollhouse level), and so finding tools that cut, drill, sand and work at smaller sizes is always nice. These tools solve one of the bigger issues with smaller and smaller tools, that when drill bits get below a certain size, they won't fit into standard chucks.. the chuck is just too big, the gap too large, and the bit too small.You can always go to a dremel, but even then, there are small chucks and micro chucks, and switching between them six times for a job is a hassle. These are nice in that they are normal sized on the chuck end, and fit perfectly, and then extremely small on the working end, where I need the tiniest of holes.They are fragile, yes. But anything just a little larger than a hair, spinning at those speeds and drilling is. With care, they work fine, and do the job required. I can use my drill press with a standard chuck, and with a little care and patience and steady hand, these do just the right job... a tiny hole, just perfect for the diorama.I wish I had read the description better, I thought I was getting a set of different sizes, which would have been perfect. Instead, I got all one size, which is fine and exactly as advertised, I just wish I had paid more attention to the exact description.
