For the record, Tungsten and Wolfram are the same metal. They have been only discovered almost simultaneously in two different parts of Europe and thus given two different names. In fact, the chemical element of Tungsten is represented by a "W".
So its like a pencil and like a pen. Good similes for me. Should I pay more for, say, the very hard tantalum carbide, or is tungsten carbide ok? Obviously, this is a minor issue compared with improving my stone carving skill. (Its world ore production in 2019 being highest in Rwanda & Congo, Tantalum is a "conflict mineral" - but the supply chain to the US is audited.) Thanks for another insightful video!
I believe that for stone carving tungsten is the carbide that is generally used. The brands I use don't specify the type of alloy but I would think that titanium and tantalum are reserved for more sophisticated technologies. Does your supplier specify the type of carbide used in the chisel tips?
Hi Mr Athar jaber.. I am interested into buying a carbide chisel to cut quartz stone.. Would it work? Would I need a hammer made from carbide too? Because carbide has about 9 mohs hardness scale while steel only have 4, while quartz is around 6.. Will the steel hammer break apart if hammered onto the carbide chisel?
So I'm very new to stone carving and using limestone I find in my local area (from limestone cliffs at the coast). Often there's flint embedded in the limestone which wear out my chisels very fast. I know flint is a bit harder than your average granite so I was wondering if it would make sense to get a carbide tipped point-chisel for taking out flint parts, or whether that material is too hard even on carbide tools?
Flints are very variable and have different hardnesses. If I were you I’d try carbide tools and see what happens. If you’re in the US, Trow and Holden make great carbide chisels.
If I wanted to split small stones to reveal fossils inside, say about 4 centimeters in diameter, should I use carbide or would it be better to use hardened steel? Also, can I use carbide to split larger stones or is it more for chipping away unwanted bumps in the stone?
Thanks for the question. I'm not an expert in splitting rocks for fossils, but from what I've seen it looks like it's done with a hammer. Probably a blunt hammer too, so that it does not cut into the stone but splits it. But again, I might be wrong...For splitting stones in general we use a blunt chisel called a pitcher. Don't forget that carbide is very hard but also brittle and it breaks easily. It's best to use it for fine carvings.

Excellent tutorial. I really like watching your videos. You know how to explain complex things in simple ways.
Thank you so much for taking the time to watch and for the kind words. It's comments like this that keep me motivated!
Bravo, Very well explained. Thank you..
My pleasure. Thanks for watching.
