I am a professional contractor & electrical engineer with more than 30 years experience. Usually, I buy American made tools and accessories ONLY. Thought I'd take a chance on these. BIG MISTAKE.

Drills arrived in POOR PACKAGING. Several had fallen out of CHEAP METAL BOX. The drills were BARELY SHARPENED & OFF-CENTER.
The drills are multi-colored - obviously from overheating in cheap oil to make them "LOOK" special.

There is no independent confirmation these are cobalt alloy. In fact, I used three of them just to drill slowly into dry oak base molding. BROKE THREE DRILLS INSIDE OAK!!! WTF!!! I will never buy tools again from the Tool Crib, or from Amazon. Stick with USA made such as Norseman, Tru-Cut or Triumph Twist. Sure, you pay two to three times more, but you'll never break one unless you use it for a chisel.

This is what happens when one try to savea few $$$ and buys product made by forced CHINESE PRISON LABOR.

This review is from: Yukon Tool YT115CD 115 Bit Cobalt Twist Drill Bit Asortment in Metal Index (Tools & Home Improvement)

My initial impression of the bit set was much better than expected, based on some of the negative reviews of the sister product, the titanium drill bit set. The shipping box was well-padded and the metal case arrived with no exterior dings or scratches. The latch worked well right away and the hinges work smoothly. The entire interior of the red-painted metal case and the enclosed bits were liberaly coated in oil. The drill bit size conversion table was effectively made illegible by soaking up excess oil, in spite of the plastic laminate covering on the table. Oddly, the table referred to titanium bit sizes. The bits are very sharp. I was not able to confirm the cobalt composition of the coating, I'll try to do that in a lab later. The bits do not have an even yellow coating on them like more expensive sets, looking more like poorly-done gun bluing, but the coating appears to be even. I randomly selected bits, rolled them across a flat surface and all are straight. The drill indices hold the bits well, but the pivoting indices that hold the larger bits tend to catch and hang up when attempting to open them up from the closed position.

However, the set appears to be fairly well made, and while the excess oil is a little annoying, I'd rather have that than rust. I purchased this set to be used predominantly on brass and steel. If I have any bad experiences during operations I will add to this report!
