While this coating is technically slightly stronger than our S2 Tool Steel bits, it’s over half a million times thinner than the shank of even our smallest bit. What this means is that when you are screwing a screw, most of the force will still be borne by tool steel. In the end we felt that there was no real-world benefit to the 5x cost increase compared to S2, at least for screwdriver bits.
Ok… so why not just use stronger steel? Well, our bits actually do use a different grade of steel than the one that Linus mangled. Without going too much into the material science, while both bits are similar in toughness, S2 steel can take more force but is more brittle. In other words, our bits are designed to hold their shape, up to the point at which they break.
Now, hopefully you are not punishing the screws of your electronics so much that you end up breaking bits. But if you are, it’s better to break bits than to break screws.
