    I have a Shars 1-7/8 insert dovetail cutter I haven't tried yet either,just waiting on time to make some more tool holders.At $56 it was a good bit cheaper than a similar sized HSS cutter.
    I just need one more tool,just one!

    I bought one from Randy Richards 6 months ago. I made some tool holder for my QCTP. Worked great they fit perfect. I did machine out the center before I switch to the dovetail cutter.

    I think this is the one presented by the OP: https://www.ebay.com/itm/352045133997

    It uses TDEX inserts. The specs are also in the listing.

    That.... was.... so... funny ... ! .... ! the person/folks that made that deserve an Oscar.....

    Back to the dovetail cutter.... On that ebay listing the strong negative rake angle of the insert faces is readily apparent in the view looking at the end. Is that not a problem? The angles it's on would scrape more than cut. Oh, I know, I know, this is metal working. But it seems like that geometry would require more power to plow through the metal just like most negative rake cutters.

    Probably done to get enough clearance angle for the insert. "Upper" part of insert is turning around with something like 10mm radius.

    Thanks for that explanation of "Vertical Video". I had no idea what it referred to. I've been complaining for a long time about the idiot stuff they have been putting on TV from such idiots. Wish I could have understood a lot of the talk on that YouTube vid.

    A couple things....

    The video in the OP's post was not upside down IMO. The way it was oriented shows the end very well.

    The Richards dovetail cutter is single flute, the Shars is 3 flute which means it could be fed much faster with longer insert life. Watching the Richards video on making the cutter it appears he doesn't mill the insert pocket with a contact angle where the 11 degree edge of the TPG insert contacts the holder, really bad practice to secure an insert against a cutting edge as he seems to do. Does he put a Weldon flat on his shanks?

    Dorian makes a 60 degree dovetail cutter that looks to be identical to the Shars, same TDEX insert (maybe the Shars maker copied the Dorian?). The Dorian cutter is widely distributed by tooling houses. Isn't it fair to assume it does a good job?

    awesome psa. Ive been guilty of the vv. I also have a set of maybe 9 or so hss dovetail cutters, they look so spindley and fragile I haven't tried to use them. But now I know to rough out the bulk of metal before using them, and maybe rig an air jet to clear chips.
