Note that the spec says drills down to 1/32". I use ER11 collets in the tailstock - they go down to 0.5 mm. However my smaller drills, down to 0.5 mm have a 3/32" (2.38 mm) shank. I have a smaller set of drills, 0.05 to 0.5 mm in 0.05 mm steps, and they have 1 mm shanks. You have to look beyond the usual sets of small drills to find these, and they are not cheap. The larger drills are Busch, bought from Cookson Gold, and the smaller ones came from Drill Services. It took me a while to find the Busch drills, and they come in at ?2.50 to ?3.50 each. However I found them to be good quality and I don't think I've ever snapped one.

The Eclipse pin chuck I have has three collets and goes down to just about zero size.
