Best diamond multi-tool blade?

[DXX]

Calling any Tilers / Builders out there with a recommendation for a diamond multi-tool blade.
I’m planning on re-using some floor slates when re-laying a floor. The Granfix adhesive is a cement based, water proof and primer was used on the back of the slate, hence it’s solid on the slate in more than 50% of the area.
I tried soaking a slate in water for days and it made almost no difference in the ease of removal.
An angle grinder is last resort as I want to avoid the mess.
I have tied a multi-tool with an Erbauer 45 grit diamond blade and it does the job but it’s not fast.

Is there a better diamond blade available for a DeWalt tool (edited, previously star lock).
Is there a chemical available that will soften the adhesive but not stain or dissolve the slate?

I've had a similar task only last week where I've had to replace a tile on the wall and wanted to grind back the adhesive on the wall. Ended up using the angle grinder as nothing else would budge it quick enough. One big dusty mess!

I've read things about using a soldering torch or a wallpaper steamer but I didn't try that as my walls are plasterboard.

I don’t mind paying the £, just don’t want to spend 3 days of my life on it.
Is a 45 grit diamond blade just the same regardless of which brand? A diamonds a diamond and the grit size is the same?

@DXX I dont know what make or type of tile ready mixed adhesive it was probably 40 years ago but we used nitromores paint stripper to soften it and scrape it off I have not got a clue if it works on modern adhesive

We used one of these with hover attached to grind down a concrete slab and remove tile adhesive from screed, surprisingly little dust!

The adhesive must be only 10mm thick maximum though?
Why bother trying to clean them off??
Just prime/ slurry and stick em back down??

There’s probably not much difference in the materials used on the blade. Starlock ones are generally better due to the design & contact/transfer between the tool & blade = Faster cutting. Hence the Bosch & Fein suggestion.

I’ve not used this below in the link before, but looks decent Grinder attachment if you have one of those. Multi Tool could be piddling into the wind a bit depending on the size of the tile.

Stop wearing high heels then

The only answer then is to use the diamond blades recommended above unless you have 100’s of hours spare and the Multi Tool blades will be ok.
Good luck buddy!

I think I’m heading outside with an angle grinder and direct it into a homemade water curtain.
