    Not too sure about this one, it's advertised a little bit wrong. States that you can use all 8 corners but you can only use 6, still need another holder to use the other two. Also claims that MCKNR holder can be used for turning but you could only use the tool in the pictures for through facing.

    That's something I had wondered about. The holder using the 80° point is definitely a facing and turning holder.

    The holder using the 100° corner to me is just a facing holder. You could twist your toolpost clockwise so that the insert presents OK for turning, but, remembering that these are CNMG inserts, I don't think that in that configuration the holder is going to hold the insert at the correct angle of attack.

    But if I was doing a heap of facing I wouldn't have any trouble using all 4 x 100° corners in that facing tool.
