This is a set of 3 of our 1.0mm drill bits, great for drilling resin and wood projects. This size is great for drilling tiny holes for Accent Pins or wiring.  These bits will work in our Spring Drill and our Creative Drill. 

If you got a Spring Drill with your Starter Kit, this drill bit requires a smaller collet than the one you have, so you'll want to purchase the multi-size replacement set instead, which includes that collet.
