How well do these hold up against carving into steel? Like for example if I wanted to add detail to a steel rod.

Hold up well. Better than I expected. I use them for finish work on guns.

The description says 1/8" shank, but the illustration shows 3 mm - which is it? (1/8" does not equal 3 mm. 1/8" = 3.2 mm.) Thanks!

The shank is 1/8th inch, I just pulled one out a measured it.

Are these good for shaping leather?

"Shaping leather"? Let's see, assuming you want to add texture or even holes to your leather, and you wanted to use drill bits, it seems like overkill to use these carbide bits, even a cheap set that can carve very hard materials at least until they wear out. I did a little net search and most references to drill bits and leather just used regular metal bits or hand tools. Careful when drilling through leather as you might start making holes in whatever is underneath. One neat trick showed leather sandwiched between plywood to hold it down, be accurate, save your fingers, and to protect your work surface. Hope this helps.

How does it do on seashells? 😆 other than that im glad it works to smooth out welds.

Hi, this item works great on seashell.

I didnot much expect this product to do the trick, these should be named Stay-Sharp Grade 8 nibbler. It turned my dremel into a die grinder! Chopped away the radius heads of 2 lugbolts within 20 mins. I did precut the head with a dremel disk and large drillbit but had to remove the round R8 radius material off the shoulder. Dont ask why but we all make bad life choices once in a while...the Lord used this tool to help get me out of that rut! Seriously brother, Praise Him!
