ᐅ Core drilling through masonry for a ventilator: which equipment should be used?

Hello everyone,

for our new build, we have decided to install a decentralized ventilation system. This requires core drilling through the exterior walls (42.5 cm (17 inches) brickwork, T9).

What kind of tool should I use for these "drillings"? Due to the air chambers, the masonry needs to be handled delicately.

Thank you very much for your answers.

Well, with a core drill ;D... I would have that done professionally...

Core drill, for example from Hilti.

Using bricks should not be a problem; this is usually something you can do yourself. Hardware stores often offer tools for rent, typically around 30-50 euros for 4 hours.

If you hire a core drilling company, they usually charge more for travel than for the drilling itself.
