You'd probably knacker it as see the same sort of reduced cutting speed that they found in the example above. It's one of the reasons they don't think the Egyptians used diamond as the abrasive.

Yeah I thought it was copper and sand

Then you're an idiot, that's been disproved for longer than I've been alive.

That hurts, a liar calls me an idiot.

You do realise it was a joke… I’ve mocked the use of copper when @Brigadier mentioned copper chisels were used to carve granite.

I’ve mocked the use of copper numerous times and and the use of sand.

Who’s really the idiot pmsl.

Glad you agree that you can cut granite using copper tools and the right abrasives though.

Have you used a core drill?

Nah, just a fork and spoon for boiler flues.

I’m not sure you can read ?

I’ve laughed about copper and it’s use all the way through this thread and just in the post you quoted.

You’re really struggling today.

No, I didn't.

What I did say was that - in response to posters who said that copper chisels wouldn't touch granite AND copper chisels could "bugger up" granite - you can't have it both ways.

Nah, just a fork and spoon for boiler flues.

So a cheap core and core bit would fly through granite?

Ok.

And then quote liberally from a study where they drilled through granite using copper tools.

I can’t remember exactly, but I said copper wouldn’t touch granite.

Please bring the posts up ?

So for clarity, do you think copper was used to core the granite ? You post in such an ambiguous manner. And seem a little forgetful.

I don’t think copper was used, I’ve said that a few times now.

I would just ignore them. They are obvious trolls. They just speak rubbish...they havent a clue. They just like to try and wind you up my friend...

Copper chisels on granite ffs

I know a stone mason, he’s top of his game.

There’s lot of work using some power tools in those few bits.

He laughed at a copper chisel!

That me, mocking the use of copper…

A slab of red granite similar to that of the sarcophagus was drilled with a copper rod and/or a copper tube in conjunction with the following abrasives: (their Mohs scale of hardness is placed alongside in parenthesis) a, beach sand (7); b, crushed quartz (7); c, garnet (7); d, emery (9); e, corundum (9); f, silicon carbide (9); g, diamond (10).
Granite is composed primarily of quartz (7), feldspar (6) with some mica (2-3).

Yeah, I think Granite can be drilled using copper tools and abrasives, as it has been reproduced.

Why dont you think it's possible for the Egyptians to have done it?

@IT Minion is just as bad loser, he’s resorted to lies and miss reporting information.

It’s sad, but I’m killing time until snooker starts
