Why do these bits have different markings on them, hss, hsco, and co?

Hello, HSSCO and CO are both cobalt drils. There should not be any HSS only drills in there. If there is any drills marked only HSS please contact us on our website at www.DrillAmerica.net with your order information we will get it straightened out for you. Thank you.

The 42 has a higher cobalt content than the 35.
