Is it for steel. Top rail of a chain link fence

Yes.

Question is about Thunderbolt Cobalt drill bit specifications

Item description does not specify either hardness (M42, M36, etc.) or Cobalt percentage (5%, 8%, etc.). Are these bit solid Cobalt Alloy Steel or simply coated High Speed Steel bits? Item description also says they are Titanium coated, probably a typo.
Asked by: ztywa6
It appears that these bits are titanium coated but they are not even hardened to minimum hardness standards. As for the high speed part they overheat using cutting oil.

I'm used to a hex shank. This only looks very thin like it will slip inside an electric drill. Is this drill bit appropriate for an electric drill.
Asked by: Nika
Yes, you can use this drill bit in an electric drill.

5/64 in. Cobalt Red Helix Drill Bit is rated 3.8 out of 5 by 438.
Rated 5 out of 5 by from Strong and sharp these cobalt bits last longer than regular... Strong and sharp these cobalt bits last longer than regular black oxide or "titanium" coated bits. However, they can be brittle and break if sideways force is applied especially on any bits smaller than 3/16".

The bits would not bite into the metal and were dulled after 2 holes. Home Depot associates told me to contact Milwaukee direct as Home Depot does not warrantee the tools. I used the every bit of this size that the store had. With using multiple bits of the same size, I say they were a BAD BATCH. Other smaller bits of the same make drilled a hundred or more holes in the trailer material without fail. Milwaukee was sent information on the bits including all package markings. As of yet Milwaukee has NOT responded.

I bought two bits to drill 1/2" holes in hardened steel, I used cooling oil, and kept the rpms low, with light pressure, the bits would barely start, and become dull, I ended up going to the hardware store, and getting a different brand. With the other bits, the holes were drilled, quite fast.

Did not perform as expected, I had to work hard to drill through a 3/8" pilot hole that I made with a 30 year old SKF bit that just cut right through and I can not find anymore. Colbalt bits should perform so much better! The step in the tip does not help at all!

This product lasted only two holes in 1/8 thick angle iron despite the fact that it is labeled as a hard metal drill and should last 10X longer than a standard bit. My old Dewalt drills did a better job!
