Got a Techniks 7/32"-3/4" ER32 collet set. My import collets don't really fit properly in my Iscar ER32 collet chuck so I figured it was time for an upgrade!

so you're going to have to let us know how they are after using them.

I have Chineese er32s some don't eject with the nut... after spending time with them. I measured the top lip and found them to not be large enough, it's not the nut, it's the collet. Thinking of upgrading the most important ones

i along with you would be interested in how they are.. i will be using ER40 on the lathe a lot
 
I have a inch set of Techniks ER40. They are excellent on both lathe and mill. I went straight to them based on advice here and have been glad I did.
 
I wonder how those Techniks compare to what Precision Matthews sell…. This is my next purchase and I am think about getting the chuck and collect set from them (PM)…

0.0002" TIR for Techniks, vs 0.0005" for PM. Just happened to be looking at both. I have an ER40 set tru chuck. Currently making the back plate for it. Going to have to buy some collets...
 
You really need to get a by 32nds set for ER40s. Collapse range is 1mm and you really don't want to do that to your good collets. 1/16" is 0.0625, which is over 1mm. So a standard by 1/16" set will have holes in it.
