"I purchased to go through a 800mm thick sandstone/random rubble wall, fantastic product, had the job done in no time, used in conjunction with Bosh Professional SDS drill, thoroughly recommended drill bit!"
"I bought this to replace a similar item I'd had for a number of years, but finally had bent it. I've only used this once and it seems perfect for the job. I'm not trade so don't know how it would stand up to daily use, but its fit for my purposes. Cheap too."
"Have only used this a couple of times and obviously its uses are limited unless you have a lot of 1m walls to drill through. No problems but you just need to be careful that you keep the drill level otherwise it will drill at an angle. Not too much of a problem with a short bit but with this the problems could be massive. I used a couple of bits of timber screwed together in a right angle to make sure I was drilling stright."
