Rated 1 out of 5 by from Doesn't Work for Tempered Steel Tried to use this drill bit to open up a hole in a saw blade for mounting purposes. Even though the package said it was designed to be used on stainless steel, the drill bit didn't even get through one hole without significant bit damage. Had to return it but fortunately Lowe's graciously accepted the return with no questions beyond my explanation. May work well for wood products but that's not why I paid the premium for this bit.

Rated 1 out of 5 by from Package is misleading Package indicates drill can be used for iron. It would not make a hole in iron. It was a waste of money.

Rated 2 out of 5 by from Not for hardened steel This bit works well for mild steel but will not touch hardened steel after the “pilot” tip cuts in. The pilot tip cuts it like butter, but once the shoulders of the bit hits the steel it’s done. It’s a shame, if the whole cutting edge were made of the same material or same geometry the pilot tip is made up of, this would be a great bit.

Rated 5 out of 5 by from Low wear, fast cutting Bought this drill bit after burning our two on hard steel in just 2 holes. One of these allowed me to finish 4 more hole and the bit still has life left in it. I was surprised. Advertised at 4X life of other quality bits. It is every bit of that for a 5% higher price.

Rated 5 out of 5 by from Really good These drill bits are the only drill bits that i have found to drill holes in quality steel. Of course, they do wear out, but their usefulness life far exceeds any other bits. I will keep buying these bits exclusively when I need to drill holes in metal.

Rated 5 out of 5 by from Very good drill bit De Walt is not my favorite brand, but this is a very good bit. Cobalt is much stronger than HSS. It works well on most materials. I especially like the De Walt starter tip. It does not skate on the material. Cobalt costs more than HSS, but it is worth it..

Rated 5 out of 5 by from snskarp carolina second one I've purchased, just work the first one out. It holds up well, works great on most metals. Haven't tried it on tempered steel. Will purchase again when this new one wears out. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great Bit I was in a bind replacing a faucet handle that was loose, except I couldn't back the old screw out. This bit drilled out the old handle in no time so I was able to finish my project. [This review was collected as part of a promotion.]
