Used this to drill through a locked door in my home that didn’t have a key. I used a normal drill bit for 30 minutes to no avail on the anti-drill insert. This drill bit got through in less than a minute.

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.

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

These cobalt drill bits last longer than standard black oxide or those gimmicky titanium coated ones do.

The cobalt bit drills stainless steel well. The Milwaukee brand performs much better than the competition.

Throw this in a drill press and it cuts through steel like it’s aluminium. Does well with a cordless drill as well. Doesn’t wander much. So far has lasted way longer than a normal junk carbide or titanium coated bit. For metal drilling I’m going cobalt from now on, the price is worth it.

Drilled 6 spot welds successfully while other drill bits broke or dulled quite quickly.

Item in great shape out of the container. Very sharp, definitely straight, and superb craftsmanship. Cut right through steel, wood and almost anything else you might desire. Excellent drill bit.

Its an odd size but needed it for my application. Cobalt bit should last for a long time

I tried several bits to drill through hard steel. This one was, by far, the best and most durable bit that I used.

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.

Strong drill bit. Works great on metal and last a long time.

These are the best bits I have ever used. They last through many uses on heavy steel. (I recommend going slow, and putting a drop of oil on the tip every 30-60 seconds.) I used this bit to drill 10 holes thru 1/4” steel, then thru a bunch of rivets, and it is still sharp!

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.
