These work fantastic, I've done stainless steel, mild and many soft metals, These cut them all like butter.I'm seeing a lot of reviews about brittleness? I think the people who break this tool are feeding it into the material way too quickly, these cut fast and deep, take too big of a cut/ fast of a feed speed and they're gonna catch on too big of a piece of material and snap. But that's how good these are, they cut every thing super easily. You have to feed it into the material at a somewhat slow pace, doesn't have to be snail pace, just don't JAM them in there and magically expect a hole.

I am used to using far higher priced center drills, at work. Since these are for my personal use (on stainless steel), I went with a lower price (but they have worked fine). So far, so good.

I still buy these because they are cheap but they break frequently. The cheap price outweighs the inconvenience in my shop.

Why these are not sold as sets in hardware stores is beyond me. But, if you need to drill accurately located larger holes in steel stock - a good hardened high speed steel center drill set is required! Every machinist is expected to have a sharp set of high speed steel center drills in their tool chest!
