Any advice for what sort of drills to use for drilling old very tough
concrete. No holes will be less that 6 mm diameter.
I bought some from B&Q that were supposed to be for concrete but they
were
a miserable failurs so were probably cheap and nasty ones.
I meant no hole will be GREATER than 10mm.
What sort of power drill are you using?
Do you need one hole, or ten thousand?
Sorry forgot the first question:
Its a bosch mains drills with hammer action.
