Questions about this item

What shank diameter does the 0.28 mm Twister Micro-Tuff drill use?

The drill measures 0.28 mm in diameter, so it requires a collet or chuck that can grip that exact size.

What collet or chuck capacity is needed to hold this 0.28 mm drill?

A precision collet or micro-chuck rated for 0.28 mm is required; standard 3 mm or 1/8 in collets will not close far enough.

How is this micro drill installed in a pneumatic tool, and what step is often missed?

Insert the 0.28 mm shank fully into the collet, then tighten evenly; the common error is leaving a gap that lets the bit walk under load.
