Bosch Cobalt metal drill bits provide 4x longer life than standard high-speed steel drill bits, plus they provide outstanding performance in stainless steel. These have been engineered for contractors and other pros who need solid, reliable bits for demanding drilling applications in stainless, cast iron, and high-density metal. These bits also are useful for general-application drilling in high-carbon steel and light-gauge metal, as well as wood and plastic. The split-point tip has been engineered for no-skate starts and clean, accurate holes. The three-flat shank design on bits 3/16 in. And larger promotes better gripping and guards against slipping. Included bits: (1) 1/16", (1) 5/64", (1) 3/32", (1) 7/64", (2) 1/8", (1) 9/64", (1) 5/32", (1) 3/16", (1) 7/32", (1) 1/4", (1) 5/16", (1) 3/8", (1) 1/2"

Not Sharpe
I paid more for these because of the name and was disappointed. 1/3 were sharp, 1/3 were semi sharp, 1/3 ( the smallest) were not sharpened at all.

Did the job
I drill out many broken bolt in my job and had a bolt that couldn't get through a bolt most likely hardened in some way from trying to drill it out. It dulled 3 HSS bits then went to this one and it got the job done hope it will get through a few more but saved a lot of time.

Durable
Totally got the job done. Drilled 36 1/4 inch holes into my storage container for ventilation. Got these bits when my standard bits wouldn't cut it. worked great and by keeping the bit lubricated there were no signs of wear or dulling of the bit. Great investment.

Solid
If you're only drilling into soft material, these are overkill. Likes: easy to open case. You know what's in the case thanks to a clear cover (not a deal breaker). Dislikes: I can't think of any since the product does what it does. Put it in drill, drill, hole, done. They're drill bits. They drill holes. There. If you want them to last longer, use drilling fluid and the correct speed.
