Hello, I have an old apartment where the interior walls consist of solid planks, tightly joined, with reed held in place by wire and finally 3 cm of plaster on each side. I'm getting a bit tired of ruining wood drills, so I'm wondering if anyone has any tips on how to proceed. For the first 3 cm of plaster, I use a concrete drill, then switch to a wood drill, but I can't feel when I reach the last 3 cm of plaster and immediately the wood drill is ruined.
Is there a universal drill bit that can be used?

I have a blåbetong frame with lime-plastered walls. Wooden interior walls on the upper floor. Plastered ceilings. I simply have a double set of drills. The same goes for the hole saws which also take a lot of wear, but what can you do..... I buy the cheap versions for the "rough" drilling.
