Description of A60J CO SET Cobalt Degrees by Drill America

Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 60 piece drill bit set comes in a metal case.

Good bit Not all bits are the same

Good bits and case. Actually they're all cobalt, but some of them aren't engraved, just laser engraved, which is a bit annoying. Some of the ones don't have "US" engraved on them, meaning they were probably not made here. but overall if that's all I can complain about. I think they are good value for money. It would cost at least another $100 to get a more reputable brand with all the bits engraved that I can live with.

Pros
  • A set of 60 drill bits comes in a metal case
Cons
  • Questionable purchase for the elderly

Good price good for twist drills

These are good quality drills at a great price (when I bought them). Larger drill bits cut through wood quickly and cleanly. Smaller drills. Not so great. I was drilling through birch and one drill bit immediately broke in half. I've never broken a drill in my life. It was a drill and not a print. Just broken. Maybe it was just bad? I pulled out an old cheap piece I had and finished the hole with no problems.

Pros
  • Round shanks allow for a variety of tool holding systems
Cons
  • I will add later

Broken beats, different finnish and random lengths.

I was pleased to receive them in the mail. When I opened the package I took a quick look at the kit and found the 1mm bit was broken. The odd thing is that it was propped up with a piece of styrofoam to keep it from looking broken. I'm wondering if this was done by the buyer who returned the kit earlier or by the seller? It should be a brand new set. Revane quickly shipped another set. When I placed the two sets side by side I found that the length of the lures varied greatly with some of the…

Pros
  • Gold Oxide is a finer oxide surface treatment than the black oxide commonly used to identify cobalt steel tools; Performance is similar to uncoated tools
Cons
  • There are new competitors
