Review on 🔩 Medium Center Morse Taper LC 21 by Flavio Iyer

I bought 2 of these bearings to experiment with. Both MT2s looked as if quality had gone into their manufacture. Both should be from the same manufacturer, but it doesn't look like it. One of them has keyholes for access to the camps. Have no other. When the bearing retaining ring was removed from the one with the keyholes, HOLY COW! what did they use to cut it? This was the worst thread I've ever seen. But for the price, I don't think you can complain.
