What are these spindle cutters?

Offered free on the mig forum.

The right-hand one is fairly straightforward - no writing, but 120x6x30 groover with HSS knives.

Left hand one - not so sure. There are no features on the back, and just those two carbide nickers.

Also, 1.25” bore and too thin for my top hats. I’m inclined to bore the centre out a bit bigger so I can loctite in a more substantial bush to bring it down to 30mm. That’s assuming I can either find the right inserts for it, or adapt it into some sort of custom cutter. Thoughts?

The Stelhe is probably a part of a stacking set, strange how it only has scribing spurs on it though. Stehle are a high-end industrial manufacturer of tooling, usually very expensive.

The groover is a Kity, they were sold with their spindle moulders.

As Trev says the rh one looks like a Kity though they usually were stamped and I think some of the tooling they supplied was outsourced, I had one I sold with my machine. No idea about the other one though.

Interesting that the Kity profiling tools are not permitted in Germany.

I would guess it's because Germany had adopted limited projection tooling as industrial standard before most of Europe.

It's the old style German cutters, my spindle moulder blocks are have similar knives albeit larger.

I would think the left is part of a stack system of cutters that interlink but as the left cutter only has the spurs it does not look like much use on it's own.

I also think the gap in the left cutter would have fit through it part of the stack system such as a rebate block or other.

The gap between the spur and the bottom of the cutter disc would just rub against a part if no other cutting tool was used to fill the gap so I'm guessing it's not much use without the other components it's supposed to be used with.
