These small bits work best in a small twist drill, but because they are high speed steel they are flexible enough for a Dremel type Rotary tool. The plastic indexer keeps the bits organized for easy selection. I believe this bit set is also offered in carbon steel which are sharper but more brittle. Select the proper set based on your application.

This is one of the few #61 – 80 drill bit sets that is sharp enough to start its’ own hole without without using a punch. More expensive but worth it!
