TINY HSS WIRE DRILLS

These tiny wire drills come in a pack of 10, which is perfect for keeping a fresh supply on hand when working with small circuit boards. The HSS steel cuts cleanly through fiberglass without snapping like the cheaper sets I’ve tried.

I needed a #76 bit for a jewelry project, and these packs of 10 are perfect for keeping spares on hand. The HSS material cut cleanly through the brass sheet without any wobble.

The #70 bits in this pack are incredibly consistent in size—no wobbling in the chuck on my first few test holes. They cut through soft brass like butter, and having ten in the pack means I won't panic when one inevitably snaps.
