R-8, 5C, ER-40 & ER-16 (?" sizes shown) collets. R-8 & 5C collects are indexed to prevent turning.
ER-type collets have wide gripping ranges & self-extract.

A 5C collet has a relatively small gripping range. Best accuracy is +0 to -0.002"
Above +0.005" may damage the work, below 0.010" may damage the collet.
1/32" (0.03125") increments are too large of steps. Most 5C collets are open all the way through.

The spin index fits the larger RF-25, much better (below). Milled ?" bolt-down slots.
This is a good place to use the ?" shank, ER-16 extensions.
