Twist drill, oh really?

Last Christmas I was given one of those big sets of incredibly cheap drill and screwdriver bit sets from my neighbour. I hadn’t touched the set until yesterday when I could not find the 5/32″ bits I was using the day before. I grabbed one of the cheap “titanium nitride coated HSS” bits from its plastic box and used it to drill out 3 pop rivets. I say 3, for that is all it managed to do. Wasn’t much to ask was it? The bit dulled quickly and became bent. I looked again at the bit, didn’t seem right to me, what do you think? A less cheap uncoated bit beside it just incase you forget what a regular bit looks like 🙂

    maybe you could use those drill bits for twist ties (closing bread packages, etc….)

      Need more suggestions as what to do with probably 100 bad drillbits…

    Looks like they hardened the wrong end… ;->

      and they couldn’t make up their minds which way the flutes should go.

        Well of course, they’re transverse flutes. 🙂
