Brilliant item for me very sharp cuts quick and lasting , for me the small sizes are to close together would have rather seen more differences in sizes but still value for money and in a case .

At last, a reasonably priced set, which can actually be used on stainless steel. Bought these, so I could drill a large hole in the top of my stainless steel kitchen sink, so I could fit a remote washing up liquid pump. I've tried a few of the other step drills on Amazon, namely the rubbish gold coloured ones, but made no impression at all. The largest of these bits, even though not quite large enough for the job, sliced through the stainless steel with ease, and by using the side of the bit, I was able to increase the hole size. Virtually no marks on the bit.

Really good quality would definitely recommend they’re expensive but you pay for what you get. Would buy again when needed definitely.
