View attachment 91317 He works for @Pro Tiler Tools hahaha

And my first impressions of the STL are less than favourable I can tell you. 🙁

Thanks very much for posting this thread Marc.

Questions. Did the disc bed in after a few runs, you metioned it was chipping a little straight out of the box? Or it was on the tile you were running it on at the time.

Whilst looking for an Electroplating factory that would make this for us we came across dozens of places that did vacuum brazed tools like the STL pictured above. We already have a product of this type which we sell as a Cut'n'Grind wheel but it is very aggressive indeed so we steered clear of them when looking for the grinding cup.

What uses is the STL marketed for? It's something I could see being very useful on natural stone but it's probably a bit too much for porcelain or ceramic.

Hey Alan,
Indeed it did chip this particular tile, straight out the box, however it did improve some over the day.
I've not tried it on another material as yet, but this is Florim Porcelain and exceptionally hard and has an extremely hard glaze. I've only had a 50% success rate when cutting it over its length. (1800)

To my knowledge he STL is marketed as a
grinding/ flush cut blade.
I've not made much comment about it because it's a completely different type of blade than what I'm used to.
When I said first impressions were less than favourable, I suppose it should have been worded better.
Sometimes it feels like too much effort to say what you really mean and just say it in the least amount of words, yeah I know, I don't do 'few words' haha
It didn't do the job I really hoped it would, and I may have been expecting too much from it.
But I will persevere for a few days and see if it improves, although for the cost, I truly expect a product like this to perform at its maximum immediately, when you're paying such a large amount of money.
Maybe I'm just being unreasonable.

If I had an improvement in mind for your blade, it would be to wrap the coating fully around the edge, so that it can be used end on in to corners more easily.

The idea of the plain edge is to act as a stopper when doing internal grinding.

I guess we'd need to make two, one with and one without the edge coated, someone would always want one or the other.

These I see as a more aggressive product, I've had a look at their video and they describe the grit as Medium so I figure it's probably around #70/#80 grit.

They will cut quicker and last longer but might not give quite as fine a finish.

I just noticed they sell fine or medium, which one did you buy Marc? The fine is probably more use for what you guys do.

Yeah the fine grit Alan.
They do indeed cut very well, it's the edge they leave behind I'm still working on.
