"Saw the bad reviews for this nut driver, so next time I was in store took half inch socket, and helpful staff allowed me to fit it before buying, (as I explained about the bad reviews). Fitted no problem, so perhaps a different batch? Works just fine."
"After reading poor reviews, I thought I'd take a chance and buy one anyway. When I tried to fit it to my SDS drill, like others found the diameter was too big to fit. After measuring the shank, I found it to be approx 12 thou bigger in diameter than the tools supplied with drill. Managed to grind down the diameter to make it fit the chuck, and it works fine now. Where is your quality control Screwfix?"
"This SDS+ bit doesn't even fit in my Bosch SDS+ drill. It looks very similar, but it's impossible to push into the chuck. You can knock it in with a mallet if you're desperate, but be prepared for fun and frollics getting it back out again."
