"This is a great tool for limiting dust when cutting new openings in occupied buildings. It will cut through most materials except hard concrete and rebar. Solid clays will take while to cut through, but when working on old buildings with lime mortar, it's sometimes safer than getting the lump hammer and chisel out (hit one brick and a different one falls out). When the blade wears, I retire them for use with softer materials. My oldest blade is totally rounded but still hacks lime mortar out no problem. These blades are also a real blessing when cutting out accringtons with thin joints and plunge cut really well."
"I bought this so I could cut a neat hole for a 2nd floor window from the inside of a 100 mm brick & 100mm Thermolite block cavity wall.
I removed enough Thermolite blocks to gain clear access to cut the outer brick wall.
Using a Challenge (cheap) reciprocating saw, each facing brick took 2 - 5 minutes to cut through, with very little dust dispersion. After about 18 bricks, the blade showed no sign of slowing down, so I don't know what the blade-life is.
"works well, enabled me to remove bricks from a hole in my wall to be repaired, have cut along about 10 mortar lines so far allowing me to slot in new bricks in place and no sign of wear yet. It should do all I need of it fairly cheaply and a vibration free (relatively!) repair as opposed to sds drill etc."
"Used this blade in a reciprocating saw when fitting new cavity trays in existing gable end wall. Used diamond blade in disc cutter first, then SDS drill with 7mm bit then this blade! Tried it first after just cutter but takes a long time & overloads saw/blade. So as long as you don't try and force it through hard pointing, it works well & saves a lot of time/hassle! Like it!!"
"was used in a saw to cut out bricks for brick repair job. the mortar was a lime mortar so quite soft and the blade cut it very easily. i cut out and replaced around 150 bricks and the blade still 50%+ left in it."
"Great for cutting soft bricks - no good on harder bricks like engineering bricks
Much less dust than using an angle grinder but they do have limited lifespan - used 2 to cut a doorway into a single leaf soft brick wall - but the amount of dust was minimal compared with using an angle grinder"
"Bought this to try and make a neat cut for a new door between old toilet and bathroom. I know the bricks in my house are very tough having a sort of black 'cinder' core but it took forever to cut though even one brick. Ended up with a bolster chisel. One thing it did do well was to cut through the mortar joints like butter. Sorry Bosch, wouldn't buy another one."
