What are these cute lietle Kaiser things for? Flycutters?

These are pretty small, they are the size of a quarter, roughly.

I'm guessing they go on a boring bar. Do they have internal threads?

Yep... threads inside...

As I recall..and I may well be wrong.....

They are the replacement ends for a larger group of units, boring bars, boring heads and so forth.

They were commonly used in automated machining as "quick replacement" heads. If you busted an insert..you simply replaced it with another very quickly. The advantage was that each was exactly the same size as the privious unit, so didnt need to retouch your tooling offsets

Hey Iggy,

Look like boring bar tips, with a coolant hole.

They're replaceable tips for BIG Kaiser's modular boring system.

Those are for attaching to a boring bar shank that you still need to buy or find in whatever haul you made this time.

Or I could make it, right? It sounds like these are kind of interesting little things.

I think you could make the other side just fine. You have the machines.

I guess the idea is if the insert blows out and you catch it in time you can re-use the bar with a new head. Usually the insert blows out, the machine is too dumb (no load monitoring) and the head is chewed up and the bar is bent or broken. Operator nowhere near to hit the stop button. But that is where I work.

Now I supose you could have a lh and rh head and use it on the same bar shank but how much does that really save? I don't get it.

Ayup. Simply turn, then thread a proper bit of rod and screw on the head. Doesnt even need to be hollow if you are not going to be pumping coolant up the bar.

You did good. Get anymore like that and drop me an email. Id sure make them and Id pump coolant up them.

Hmm ... they look like screw-on insert heads for boring bars to me.

Ones designed to bore to the bottom of a blind hole, if you have CNC or some other way to reliably stop the travel at the same point every pass.

Looks as though you have at least three sizes there -- determined by the offset from the shank which would be a continuation of the cylindrical part.

Perhaps the hole is designed for flowing coolant through a hollow boring bar and to the insert.

Any clue what thread is in the cylindrical end?

I would kind of like having those. They look a reasonable size for my 12x24" lathe.

Enjoy, DoN.

O.K. For boring head use, not lathe use, and the expensive parts are not with the insert heads. (Things like the BT-40 holder, the boring head, and the (less expensive) collection of shanks.. But they could be used in a standard boring head or a lathe as well with a bit of creative part making.

Enjoy, DoN.

Those kits are "universal" Don..you can use them as lathe bits OR mill boring head bits.

Simple enough to make shanks.

They could be used on a lathe. The the thread is not metric, I could make a holder bar.
