Microstix Bits
These bits have a 4 mm HIOS shank. To fit in a 1/4" hex shank driver, use an adapter (sold separately).

Hex Shank Taps for Drills and Screwdrivers
Insert these taps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. They're made of high-speed steel and are for use on most metal and plastic. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
