very nice,what else do I need to say

works perfect!

You cant go wrong with Starrett. I purchased this because of Abom79s use and didnt really think I would use it. Not 24 hours after it arrived I found myself using the Indicator Hole Attachment to get a largish item centered in the four jaw chuck. It took a painful task to an easy task.

Indicator mount hole was powder coated and required reaming to slip on my Starrett indicator.

works as expected

Wow a great price on a brand new Starrett accessory. The price is less than these things go for on the e-bay used!

OK, works as expected.

For work.

Very nice! Exactly what I expect from Starrett. Minor nitpick was that the hole to attach to the indicator stem requires cleanup with a hand reamer to remove the powder coating.
