Mr.

These cobalt drill bits are the only thing that will drill into hardened bolts and metals. I have tried standard bits on hardened metal before not knowing what grade the metal was. The standard bit dulls almost immediately so I reach for the cobalt bits. They will sink on through the metal with no problem. The only cons are they are more expensive and they will break easily if you put force perpendicular to the bit instead of linear.

5 out of 5 stars review

10,000 Screws in a ThinHaus Means 10,000 Holes

When you drill as many holes into steel studs as ThinHaus does, you need an excellent bit that starts sharp, stays sharp and will take a new edge. These bits do all that and they are the "official" drill bit of ThinHaus.

Cobalt Bits

I' m a tradesmen working for my self so I need quality & durability. Irwin has both at a reasonable price. Cobalt bits are designed for harder metals like stainless steel so they are more brittle then other bits and do not tolerate any flexing .If you wabble them to widen a hole they will snap. You must use exact perpendicular force to the work surface or they will snap. So slow down the rpm but increase the pressure. Cool the bit down with water or use cutting oil they will last many times over.
