Thread: Some tools i don't recognise

A while back I bought a CC tool post grinder from a deceased estate.
It was in pretty bad state, but it was a pleasant journey for me on restoration.
I can use it as a simple surface grinder now even though I dont have a magnetic chuck.
There was a couple of prune tins of bits and pieces, including these three tool bits.
I'm guessing they have carbide cutters braised on to the ends. I also guess they are for a big lathe, but now I'm stretching my imagination.
My questions is, can I put them to use, and barring that are they any good to anyone who might have the necessary giant machine to take them?

I cant help but think there should be a picture here

No no, its a puzzle question. We all offer up guesses and the one who is closest wins the tools

They are Clausing Colchester tools. I have one and will let You know My address.

Do you mean CC Tool and Cutter grinder?

Hopefully, here is a pic now.PA251067.jpg

Yes Old Rusty Toolie thats what I ment

Those carbide tipped tools bear a remarkable likeness to the tips supplied on rock augers made by a well known South Australian maker of tractor mounted post hole diggers. The very negative angle of the inserts suggests a rock digger application. Just my opinion,
Combustor.

Thanks Combustor--I did get comment they were teeth off a post hole digger but it makes more sense if they are off a tractor driven one.
I wondered if they could be 'tweaked' to make lathe tools for my little lathe?

Not just tractor ones, Proline made truck mounted crane borers commonly used in the mains power transmission line pole installation.

Is that a joke? There's a whole industry in what's called "Down hole tools". Its just the snarliest, toughest / roughest grade of Carbide available. It doesn't have to hold up to a sharp edge, it just smashes rock. Post hole drill / auger. Sintered micro grain carbide comes into its own, as a cutting tool. It will also has Cobalt in it.

You'd be wasting your time trying to turn them into lathe cutting tools. They'd perform nearly as good as HSS then crack. They don't take heat
