How to make a hole in transition between leca and sill ?

[Raufus]

Hello, I am installing a sepparett and just realized that the connection to the urine separation (approx. 40mm) needs to be drilled at an angle, right at the transition between a plastered leca base and the sill plate. Is there a neat way to drill in both wood and leca? Is a hole saw the best option? The wall is about 15mm thick.

Thanks for the response! But does it really work on wood? Won't it just burn (even at low speed)?

It probably carries along some wood as well.
