core drilling like a gangster 

Seriously don't do this.
It's very dangerous, I'm only doing it because i'm the nuts of course, In reality, this is the type of stuff that goes on the job, gota get done done pilot bit or not.
But if anyone wants to send me a pilot bit , that would be great 😉😉. #plumbers #construction #builders #powertools #tools #toolhack #toptip #plumbing #plumbing #plumber #builder #plumbers
