What else is a lifetime warranty supposed to mean on a drill bit? It's not something vague like the "100% satisfaction" you linked.

If they offer the warranty on drill bits, then there's nothing wrong with using the warranty on drill bits. It's not being a bad customer.

It's kind of like returning sandpaper that you've worn out though. :/

Same thing, if the sandpaper has an over the top warranty for the product category then it's fine to use it.

I’d totally bring one back if it failed because they forgot to harden it or something. Put it in some wood and the first time you use it the threads reverse because the metal is so soft.

It is plausible that it did not live up to reasonable expectations in some way. Equally likely that someone was being dishonest though.

Example: I once returned a board that I had cut in half. It was window trim with a shaped profile, and I had previously purchased and installed some of the same SKU before. When I went to install my freshly cut board next to the first ones, it was a little too obvious that it was from a different batch or manufacturer with a slightly different profile.

> Wait. Someone returned a drill bit (a wear item) for replacement?

Could be. Maybe it snapped?

I've snapped dozens of drill bits in my life (from many different brands). Exactly zero of those were a manufacturing defect.

Oh, I agree - I've snapped dozens as well due to misuse.

But it is not inconceivable that a bit snapped due to manufacturing defect (I just don't know how the store can tell the difference).

The bit had snapped in half iirc, not worn out.
