'Medium' thickness 115mm diamond disc?

[JohnW2]

Hi folks,

'Standard' 115 mm diamond discs (for angle grinder) appear to have thicknesses ranging from about 1.2 mm to 2.2 mm. Others, with thicknesses using in the range 6 mm - 10 mm are sold as 'mortar raking' discs.

Is anyone aware of (not too expensive!) ones with thicknesses in the 3 mm - 4 mm range?

Thanks.

Kind Regards, John

Yes, I've seen that one, but 5 mm is not much thinner than the countless 6 mm (and thicker) ones also sold as 'mortar rakers). As I said, I'm really looking for 3-4 mm, if such an animal exists.

Kind Regards, John

Thats a grinding disc, only seem available in diamond upto 2.3mm and then start again with mortar discs at 5mm, abrasive ones for stone are available in 3mm, have you looked into is it possible, and safe glueing 2 together? did come across this, albeit mortar raking blade.

Mortar Cut Diamond Blades

The mortar cut diamond disc blades from Right Lines incorporate either two or three diamond blades to efficiently rake both hard and soft mortar.

Thanks - but, as has been said, that's not really a cutting disk.

As I've said, that's essentially what I have discovered.

I'm done that in the past to improvise a mortar raking blade, but it's obviously not a very nice approach!

I may well be stuck with 2.2/2.3mm ones - which will [probably be just about think enough for what I want.

Kind Regards, John

For mortar raking ashlar joints the masons I've worked with (I live in a stone district) just make 2 cuts and rake the waste out...

As to being safe to double up blades, what does the grinder manufacturer say? I bet there isn't a single one out there who recommends this in their manuals

Sure, if one wants something pretty wide, that's how it's often done. At least some 'chasing machines' I've seen have two blades, spaced apart, which achieves the same in a single pass.

Of course there isn't. However, some of the wide blades/discs around consist of two or more welded together at their centre.

I'd just put two in side by side, but a) I'm rough and b) willing to be reckless thus.

I've also had great success mounting two diamond blades side by side in a stihl saw to cut a 10mm guide slot (and also remove as much material as possible with a far cheaper pair of diamond circ blades) for a stone chainsaw cut, but it did take a lot longer to spin up and had a much stronger gyroscopic effect. Be careful

As I implied, I've done that on my time (probably because I have the same characteristics as you ), but would really prefer a more 'decent' solution!

I'm sorry, but I don't think it is a good idea to condone the mis-use of power tools, on a public forum.
And especially with regard to angle grinders, the tragic story of a former DIYnot member, appears here from time to time:

This is notb665’s partner and mother of his son. I also have a daughter that he also treated as his own. He passed away on the 19th of December. He had an unserviceable injury from an accident at home. I do not wish to say what happened, but I was with him at the end so he did not die...

Nothing in my post condones, it merely says what I would do. It also carries an advisory of the consequences and a suggestion to be careful.

I work within the limits of what I'm prepared to tolerate; so should anyone else and we are all free to behave as we choose
