Did what I needed it to do.

I needed to widen 4 7/16" holes through 1/8" steel. The bit accomplished this, though I don't know if it would have done many more. They last hole took a little time, but it did what I need it to do, so that's worth four stars to me. I also used a drill press as I can't imagine doing this with a hand drill (I think that would be difficult with most any bit).

Bit was pretty will shot after 21 holes

Used one for drilling solar mounting holes through an asphalt shingle roof. Bit was pretty will shot after 21 holes. Something about drilling through hard granular roofing.

Quality Bit at Good Price

I needed a bit for cutting two 5/8" holes in 3/8" steel for a farm implement and found this one on Amazon at good price. It performed better than I expected. The IRWIN bit is made of M-7 high speed steel for extended life. It arrived sharp and in its own package for storage. I set the recommended drill speed as close as possible for the 5/8" bit diameter and material (steel) according to the table on my drill press. A pdf version of a table can also be downloaded from IRWIN that includes the bit sharpening angle. The bit moved easily through the 3/8" steel with no chatter or binding using my old drill press with manual belt speed adjustment. For the novice, it may be instructive to read up on the basic rules of drilling metal by searching on-line the words drilling metal etc. Some advance reading can keep one from making mistakes in judgement since the rules for drilling metal can be counterintuitive; such as not using cutting oil for small bits at low rpm; or pressing harder (rather than lighter) to reduce tip heating by generating continuous spiral cuttings rather than chips. For safety, wearing eye protection and mounting the workpiece securely are always musts.
