Is There A Definitive Article On Collets

[higgite]

Brockwood,

That's a handy reference to have but, I noticed an error in the ER 32 Row. The US Size Range shows a max of .118 when in fact a standard US set will go up to 3/4.

There's also an error for ER20. Max should be .512".

Revised chart. The original chart was just for metric & expected some collets to tighten down below nominal size. In this chart only min & max nominal size is given. ER8 & 12 are only available in Metric sizes. All other styles include both a metric & a imperial set.
