Really? You want me to review a drill bit? Umm, it put a hole in the material I wanted so I guess it was at least good.

It drilled perftly through the bolts I was trying to get off of my lawnmower. I would recommend trying it for yourself.

Broke off an exhaust bolt and had to drill it out. (in place) Bought the 3/16 Cobalt as my starter size and also the appropriate size called for, to tap out the threads. I was surprised how easily these bits drilled through the old steal bolt.

Great bit. Very sharp. Went thru the wood like butter. Had some issues with the metal plate behind it, but it eventually penetrated it also.

Very good quality drill bit. I was able to drill through a quarter inch thick metal plate with relative ease.

The best type of drill bit I use to work on stainless steel, the only bad point about them is that they are very fragile and break at the first mistake made during a manual drilling operation, but using correctly , they are the best!

I bought this to drill through a metal plate that I could not see inside a brick wall. It did not go through. I tried it on some scrape metal and it went through clean and fast so not sure why. The other issue was I bought a Milwaukee bit extender to reach through the wall and this bit would not in fit the 1/4 inch holder.

Working on a deck project that requires me to drill into aluminum posts. This drill bit appeared to be the best that Home Depot had to offer for a metal project.
