[Dremel or smaller size] Diamond Saw Blade

[Michael GilliganParticipant @michaelgilligan61133]

Here's a screen grab from the latest epidode of "Digging for Britain" … featuring a [presumably] Diamond saw, on a transparent disc.

.

Does anyone recognise it, please ?

Does anyone recognise this blade ? ….

Could it be an optical illusion due to holes in the disk? Something like these dremel diamond cutters on amazon.

Could it be one with holes but due to the speed it appears as though it is a clear material. If it was plastic any heat build up may effect the clear plastic and distort the disc.

Edit cross post with SOD above and they are what I was thinking of

Thanks, gentlemen … I did wonder that.

I have already written to Dr Madgwick, and will report back if/when he advises me.

On eBay, from China, but for £3 I will take a chance.

Or try a lapidary shop, they use fine diamond discs to cut stones, rocks etc. They also cut composites which is why I got mine!!

cheers

The amount of "solid" around the edge looks a lot thinner than most of the drilled discs that are about would show when spun up but you may want to look at the dental ones such as this which only have a small amount of diamond coating around the edge

I think Jason is probably right, my brother in law was a dental technician at the local hospital. He once showed me around his workshop and I can remember seeing a small holder with a range of very thin small cutting discs, not the type you would normally see for sale.

[Michael GilliganParticipant @michaelgilligan61133]

Well folks … as you may have noticed, he was sectioning a tooth

Michael, have a google for Kerr diamond cutting discs

Ron

[Michael GilliganParticipant @michaelgilligan61133]

That looks promising, Ron

Some of their's are slotted, rather than being perforated with  big round holes … so the optical illusion would probably be more convincing.

I haven't watched the programme yet Michael but are you sure its a tooth and not a bone that he is sectioning? It doesn't look to have the right structure and shape for a tooth.

 Oops !!

Apologies for the sloppy error on my part

Helpful resonse from Dr Richard Madgwick :

It's not actually transparent – it has spokes, but you can't see them. It's a flexible diamond wheel that dentists use. I get them from prestige dental and they're about £12 each I think.

Thanks for the interest, everyone

So are you taking up DIY dentistry as a hobby for the new year?
