Arrived very quickly. Not overly priced and looks good quality.Unfortunately I haven’t had a chance to use it yet!! I doubt it will disappoint

Very sharp and easily drilled into stainless steel
Easily drilled into tough materials, including stainless, leaving a very clean hole. No sign of blunting after drilling about 30 20mm holes, but I haven't used it for long enough to know how well it will keep its sharpness.

Cheap for what it is
Went blunt after first use, 2mm mild steel. Tray work

Hard as nails, well much harder actually….
A really useful tool. Expensive, but it isn’t made of cheese like the Chineseium alternatives.

It works
Goes through stainless steel like the cnc drilling machines I used to work with, so I know what I’m talking about. I was actually surprised it did go through a very smooth and hard steel so easily.

step drill
Rather disappointing (very!). I tried using this to drill through a thin sheet metal panel (car body work). It really struggled to start a hole so I swapped to a standard HSS drill bit which easily penetrated the sheet steel panel. I then swapped back to the step drill bit which really struggled to cut through the thin steel work which after a few minutes I did create a 20mm hole. However, repeating the exercise to drill a second 20mm hole completely failed. I reverted to my metal circular saw bits which glided through the thin steep panels. This step drill bit is not suitable for what is advertised. I strongly urge people to look at alternatives.
