    BT,
    Interesting. I'll keep that in mind when I order my ER set. Sounds like metric cutters with metric collects or imp cutters with imp collets would be ok. Although I seem to remember some meter/imp ER collet sets are the same sizes with different numbers on them, but I can't remember what system they infact were.

    That article makes some sense...shrink fit tool holders are said to be the most rigid, chatter-free system available. Squeezing down a nominal 10mm collet on a 3/8 shaft does have issues as discussed in the piece. Likewise a 1/2" in a 13mm-you get the idea. I do note however that they are talking about demanding applications. I don't think I'll be doing a lot of thread milling on my manual mill. (dammit)

    No. But there's every chance that you will use a dovetail or tee slot cutter.

    100% chance, and I do take your point. Have you ever seen imperial ER32s that were what they claimed to be and not a re-labeled metric?

    From what I have seen Eskimo is a perfectionist, he even made up 2 fly cutters so he could work in both directions of the spindle.

    and don't forget to tell them all that I can measure the X&Y of the mill table for being level at the same time with-out having to move the machinist level...now that is perfection?......hahaha
