Recommendations for multi tool blade for brick/plaster

[Gavin John Hyde]

I am looking for recommendations for a decent multi tool blade to cut through plaster and some brick/block. I could use a standard blade but it will kill the blade.
Have a job coming up where it needs some delicate cutting without going too heavy on the wall. normal chasing isnt an option. likewise disc cutters would be too intense and heavy handed.
I used to use decent erbaur ones, but they are no longer available.
What makes/blades are people using ?
I will be making a series of cuts to make a narrow chase and then sink a shallow box in for a switch. the chase will be less than half an inch wide, the customer has agreed to this so that it avoids too much remedial work.

No worries happy to help! Bosch make some similar ones too but I like the irwin ones as the are 150mm long and seem to last for ages!
Yeah most of the grout type grit edged work well with plaster, I have used old normal blades before on plaster just cut a series of slots in it with a 1mm cutting disk in the grinder. They leave a really crisp edge to the cut and produce minimal dust but only work on plaster.
It takes some skill and patience to do listed buildings and some luck as well. My pet hate is lath and plaster, once disturbed is a bugger to make good!
Got to love a scutch they are much neater IMHO!
All good fun!
All the best

A quick Google got this . At £20 a crack and the wear on the machine you will need a helluva mark up.

I would suggest the Saxton ones, the diamond tipped ones...they work well in mortar and soft brick. I used them to take out a glass brick wall, and they sliced through the mortar easily...unfortunately, when they encountered the nylon tile spacers they clogged up.
I have recently tried their multi=purpose wide blades, and they are great for general cutting, slicing, back-box cutting etc.
Don't be too precious about blades...pay the price, save the time, fling them away...
Old blades are slow, stutter and fart, go off line, take ages to finish the job...who needs that?
Charge the customer! Buy good blades!
