Diamond hand pads or polishing discs

[dg-1984]

I am looking at getting some hand pads or the polishing/grinding disc for a few DIY jobs coming up.
And looking for advice on what would be the best to buy as they will only be used for DIY.
I already have a rotary polishers that I can use for the discs if these are better.
Kitchen splash back with Porcelain and have a mitre cuts for round the window. Will take most the meet off the tile with the grinder before finishing it.
Also have ceramic tiles 600x300x9 for a small toilet that I am doing half height all way round and have 1 outside corner to do.
What grits in each would be desirable?
Thanks in advance.

I use (usually) semi-hard velcro backing pads and norton abrasive paper discs. Makita variable speed 115mm grinder, dry.
For porcelain - 60/220/400.
These get my by for mitres, and are also suitable for most stone.

Do you fit the backing plate to your grinder? I will be buying the Bosch variable grinder.

Thank you, I didn't realise it was an M14 on the grinders, I have backing plates for my rotary polishers that would do the job.
That grinding disc looks interesting.

Doing some this week. Probably cost me £30 for the set. Used them on ceramic and porcelain.

The one julian posted looks good as it looks like fine diamonds on there. That’s where you need to be careful. Using sanding pads etc takes out the risk of chipping. A lot does depend on the tiles you’re mitring though.

I’ve never used the paper abrasive pads so can’t comment on them or compare. I must get some at some point.

The diamond discs I have seen and look interesting aswell, read they need bedded in alot to get them to work and as it's DIY wouldn't get alot of use.
Where did you purchase them, seem some on eBay that look decent at £4.95 per disc so can select the grits you need.
Did you mean the grinding blade can cause chips?

I've got a full set of diamond pads. Used twice. In my experience they've no advantage over paper discs. Especially in dry use.
The stone masons have been twiddling edges far longer than us tilers have They've got the techniques and materials sorted already.

I found that this leaves some chipping in porc. Am I using it wrong? It hasn't had much use.

A poor grinding blade will chip.

Being honest, I will cut a mitre in porcelain using a standard cheap Chinese blade and finish up with a Montolit STL fine blade......the only reason I think the sanding discs might be useful is if you’re inexperienced.

I have used them on the odd occasion for mitring though.

Yes, the sanding discs can be bought from the likes of eBay. So cheap that it’s worth finding out for yourself if they’re useful.

Gee whizz those prices are excellent what is the quality like.

[J Sid]

We ship all over the world.

Unfortunately the factory supplying us with the dished electroplated grinding discs has fallen fowl of a Patent and we've sold out of our original stock purchase. We're trying to find the Patent owner and buy from them, but no luck so far.

We've also tried 6 further versions of this product, none of which were suitable.

So it's looking like it will be out of stock for a while until we find a suitable replacement.

Is there anything else close you can recommend?

 

[Concrete guy]

Is there anything else close you can recommend?

At the moment no, it took us a while to find this product and we were asked by a number of people to find it.

So it was disappointing to find we couldn't buy any more as they were a good product that was well made.

 

[Waluigi]

What is it, a fine diamond on there?

A good price for that. I’d be interested in buying one if you get some stock. Keep in mind that the Montolit fine diamond disc is £80 a pop.

It's #120 grit electroplated diamond.

It was a product we sought out as a result of multiple requests from forum members.

The Montolit discs are vacuum brazed diamond and a little too coarse for controlled grinding.

What grits would you recommend?

 

[dg-1984]

The ones I am finding are in packs of 25 or 50. Only looking for a couple of discs in a few grits to do a couple DIY jobs.
Anyone know where I can purchase a few discs. Or even if any of you good people have spare I could purchase some from you.

The fine one is OK IMO, pretty smooth blade. A whole world apart from the vacuum brazed imitation Montolit I’ve seen.

What speed on a variable speed grinder should you use the electroplated diamond grinding disc?
