Here's my suggestion: Sooner or later, for some project or another, you'll want a Dremel. Now, they come with a collet for drill bits. So, buy a Dremel tool with an accessory package so you get all of the tools, and then buy a little drill bit package with sizes from 1/32" to 1/4". Unless someone has built the plane, then we have no idea about which sizes are needed. But again, sooner or later you'll need every size that's included, so there's no point in buying each size individually (don't know who would do that). -Andrew
