Go slow
They are brittle so be careful that's just how cobalt bits are, they won't tolerate bending or biting off more than they can chew. I'm drilling through 4 10.9 hardened steel bolts (seized subframe bolts) I drilled through one so far. Use oil, go slow, push kinda hard, keep it straight and clear the chips and your good. Stop often and add more oil and don't let it get hot.

I wouldn't buy again
Not as great as advertised. I tried to drill thru some steel L and the bit would not go through. I use a lot of drilling oil and it didn't matter.

Sharp Drill Bits
Small, but handy drill bit plastic case. Drill bits are sharp and do the job. Recommend

Small number of bits but for pilot holes its perfect!
Not a huge selection of sizes but for pilot holes? Great! These bits cut like a hot knife through butter. I'm pleased with this purchase.
