That is cheap, but you still need to put a collet in each one. A DIY TTS compatible tool holder blank, drilled & reamed, with the tool held by a grubscrew would probably do for woodworking, e.g. : https://www.youtube.com/watch?v=_2w8cYXt5_o I'd make 'em on the lathe, rather than futz on a small wobbly mill, as he does. But he says they're costing him $5 a piece, ready to go. Dunno how good that kind of holder is for precision work. How much eccentricity would the grubscrew introduce on a tight fit? I'd also be tempted to use a slot drill or end mill for approaching the final size, to leave a flat lip at the bottom of the hole, for the tool to butt up against.
