ᐅ Chases in Poroton T12 blocks

Hey, as mentioned above, I’m looking for a way to cut the channels for the wiring myself.

Online, there seems to be no upper price limit for wall groove cutters. I’m aware of the saying that buying cheap means buying twice. That’s why I’m just looking for opinions here on whether it’s worth investing around 200 EUR for a wall groove cutter. If so, do you have any experience with specific models?

Another question: Is this even possible with the uneven T12?

Best regards,
Florian

There are also rules to follow when chasing walls. Do you know what you need to consider, and is it even allowed for a layperson to chase walls?

These would be the first questions I would ask myself.

After that, I would go to a hardware store and rent one, because you will probably never need a wall chaser again.

Renting is usually much more expensive than buying and then reselling after use.
In my experience, the most cost-effective way is to buy a good used tool online and then sell it afterwards.
Regarding your actual question, you can also make the slots with an angle grinder; you just need to run it along twice, which we also did. If you can handle the dust that will inevitably be generated, that would be the easiest option since most people already have an angle grinder...

Hi,
using an angle grinder is really just an emergency solution to quickly cut a forgotten groove. Nothing more! The amount of dust generated is absolutely huge!
You really can't go without a _good_ wall chaser WITH dust extraction.
Don’t forget respiratory protection—you definitely don’t want that dust in your lungs...

Best regards,

I already mentioned that the dust is significant, but during the shell construction phase, it’s not that critical.
In the finished house, I would definitely avoid it.
In terms of handling, I actually found the angle grinder even better than a high-quality corded grinder I borrowed from a professional.

You should also know how to use an angle grinder properly if you want to make clean chases. A wall groove cutter is more forgiving, but an angle grinder can easily slip and cause injury.
