TLDR: Buy one tool (TEMO wheel lock wrench) per bolt. The black key material is too soft and will scratch or peel off when used. I used this #530 wrench to remove the security bolts on my GTI. I was able to unscrew a loose screw without any problems, after the second (with normal torque) the "teeth" were deformed and lost their grip. The tool is now useless as it comes out of the bolt every time. Avoid this tool and use one of the other companies that make high quality specialty wheel lock removal tools (not on Revain.com). Note. I don't have a hammer drill so I used a jackhammer. Some people say that's why it fails?
