"This is the tool to make life easy. Used for the first time and now wonder how i would have done the job without it. The carbide does a great job, completed a wall section about 6mtr by 5 brick high and the carbide could do with replacing as although it is getting through the mortar it is not as easy as at the start however a great tool and would buy again, this is why 4 stars for performance."
"I used this mortar rake to rake out the old mortat between the slabs in my patio, prior to repointing the slabs. The mortar rake worked extremely well and lasted a great deal longer than I expected it to do.
I did in the end assist in extending its life by taking a relief cut down the centre of the mortar line with a 9 inch angle grinder & then went back over the run with the 4 1/2 inch angle grinder with mortar rake at which point the mortar was just falling out the joints easy peasy. Would deffinately use it again & highly reccomend it to others. Not tried it on brick work but I'm sure the same principle would apply. Didn't rate the features high as it has only one but it does that one thing very well."
"This made short work of some old badly re-pointed Victorian mortar. Went through it in seconds making it easy to remove a good depth. However, up against modern cement based mortar it struggled, so I'd only recommend it for the crumbly stuff. Seems a bit pricey in that regard, but worth it."
"I used these to rake out Victorian lime mortar from the joints between soft Victorian bricks – they are ideal for the job. They will also cut through these soft bricks if required (but why would you) but they are not really suitable for modern cement mortar, which they will cut very slowly while wearing out quickly. They are much better than a cutting disk for the perps because there is no danger of accidentally cutting into the bricks above or below.
Consider them as consumables like cutting disks – I found that they last for around 500 bricks on average before the abrasive wears off. If you get kick-backs from hitting hard objects or from rattling around in the joint the abrasive end of the tool can snap off prematurely, but not as prematurely as one I bought from another place that had better remain nameless. For this reason I would suggest that the manufacturers incorporate a curved fillet rather than a sharp angle to avoid the stress-rise weak point between the base and the working end of the tool. With this I would have given five stars.
Of course this tool generates clouds of dust and grit, enough to kill a cheap angle grinder if you don’t take care to avoid it getting sucked into the motor. Don't ask me how I know this.
