Saw the photos & CCTV of the vault robbery. I'm not familiar with cutting holes in reinforced concrete,although I have seen it done with a thermic lance, but I was well impressed with the hole(s) they cut. The police believe that it was done with a Hilti that they nicked previously, if so that's a bloody good advert for Hilti.
Apparantly a Hilti DD350,which would cost about £3500 to buy, was used to drill the hole. Hilti could make a brilliant advert. As to the crooks, they deserve A* for style, originality & neatness of their work...
Hope the Old Bill don't subscribe to this forum Phil, or you might have to replace your door when they smash it in. LOL
Sadly there's only a £20,000 reward for info leading to the arrest of the perps. Thought it would be a lot more than that.
