Works.
We have concrete mesh walls that are a pain in the butt and these are stronger bits than a hardware store has

Hands down the best Drill bit for vehicle frames
Worked amazingly well to drill holes in a truck frame for a fifth wheel install. I was skeptical that these would not burn up quickly but I only ended up using the one. for the whole project.

Really happy with these so far
I've been using titanium bits to drill thru EMT for years. I decided to try the cobalt bits. I've drilled 16 1/4 holes using 1 bit so far. It has been so much easier & faster. I was going through a titanium bit every 4 holes.

Overpriced gauge
This little gauge feels flimsy. Material is pretty thin. The marking on the depth gauge is difficult to read. Only 1 video is available. Very little instructions on the box. No manual. Still can't figure out the router bit gauge. Chisel and drill angle are not that useful. In the end, this 5 in 1 gauge is reduced to just 2 functions. Overpriced.

They get the job done
I appreciated having multiple bits as they didn’t last drilling thru stainless 1/2 inch plate- but I don’t suppose any bit would. These were ideal for getting the job done and are definitely affordable.

Needed re-sharpening
First one lasted 10 holes into 14 guage stainless steel at slow interval rotation. Second lasted 2 holes. Had to re-sharpen.

Great quality and value
I install commercial steel doors for a living. These bits are easily as good as any name brand at home Depot like DeWalt or Milwaukee.

Excellent Drill bits and Value ~ 1.864" ~ 47.33 mm long
These 1/16" drill bits are about 1.864" ~ 47.33 mm long.These are excellent drill bits. I've been drilling multiple layers of loosely packed thin, flimsy plastic with them. They center nicely and they actually drill through the material properly and not just tear a hole in it.

Not perfect
Work ok and the price is right. On close inspection note that not all the point are sharpened correctly. no problem if you own a drill doctor.
