"I ordered 8 of these bits to drill 80, 150mm deep holes in concrete. 3 of the bits were not straight and could not be used, of the others 1 was dead straight and two less straight drilled all the holes, so they did ok when straight.
I knew I'd need a few of these as cheap drills don't last long but didn't expect most of them to be bent!"
"Not straight! This means the drill oscillates violently in your hands, accurate hole placement is impossible and the hole size ends up bigger than it should be. I would just like to add that this wasn't a result of abuse, it was like this from the first hole drilled! At first glance this drill was a good price, but not when you factor in the time to go back to Screwfix, complain about it and then get a decent one. Wouldn't recommend one of these and won't be buying one again."
