that is because ANY bit that is "coated" have junk steel underneath. At one of my jobs I used to take about 500 drill bits a month to a local sharpener, if a bit was coated, he threw them in the trash. In my own use in my garage, the coated ones are the only ones I can afford so they work pretty good, but if you get them hot, trash it!

Ask Irwin
Q: Are Irwin cobalt drill bits coated like the titanium ones? If the cobalt bits are rockwell hardness 66 - 67 HRc, what hardness are the titanium bits? Once you sharpen a cobalt bit and the gold coating is gone, is it just a regular bit?
A: Cobalt bits are not coated, they are cobalt steel through and through. At the end of manufacture a cobalt bit is baked in an oven to turn the surface color of the steel a dull gold color. This is done primarily for easy identification by color. If the gold wears off or is ground off in sharpening on a cobalt bit, it is still solid cobalt steel. Our cobalt drill bits are made of M42 cobalt steel which has 8 percent cobalt content. The Rockwell is approximately 65.5 to 67 Rockwell C. Irwin titanium drill bits have a hardness of approximately 64.5 to 65.5 Rockwell C. The titanium coating is much harder at approximately 82 Rockwell C. If you sharpen a cobalt bit it is still as good as a new bit, assuming it was sharpened correctly. If you sharpen a titanium bit its performance will drop because the coating is gone on the tip; however, you still have the benefit of the titanium coating in the flute of the bit and on the sides of the bit. It will still perform better than a standard bit.
