I have one. It is very nicely made and does an excellent job of cutting dovetails, in aluminum, cast iron, and steel in my experience. Randy is a friend of mine, a truly nice guy and an extremely knowledgeable machinist. Randy worked as chief engineer on large ocean tankers, now retired. If the main engine failed, you weren't going anywhere until you got it running again. He can make or fix anything. I paid for my dovetail cutter, and don't owe anything to Randy. Just posting an endorsement from knowing Randy and working together with him. Talk to Randy, the dovetail cutters like to be run FAST.

It would probably work well. I made one with a TCMT insert. His insert choice, with front clearance is better (I ended up grinding some front clearance). I was happy with the result, but the tool really hammers because of the long cutting edge. I probably should have used a larger shank (5/8") - but at the time, that was the largest collet that I had. The entire set up needs to be really solid.

The one I got uses TPGB321 inserts. Because the cutter is going round and round the inside of a fairly small radius, it needs a lot of relief behind the cutting edges. The inserts in your pics appear to not have enough relief. Lathe inserts will NOT work for rotating cutters doing inside work.

Don't know. Randy only had one size when I bought mine three or four years ago. Mine uses a 3/8" inscribed circle insert, and has a 5/8" shank. Beautifully made...

Does he have a website you can order from?

Not true, I made one as well using a TCMT insert and it works very well in soft materials like aluminum and steel as well, but that being said, the TPGB does work better as I made a second one with this insert.

I bought one of Randy's cutters a couple of years back. Used it a couple of times, works great. Nice guy, I watch all of his Utube videos.
