  • Drill bits are coated in tungsten carbide. Sometimes. There are a variety of coatings.

    The drill bits you’re buying at the big box store are high speed still with some kind of coating to help them last a little longer. The specialty drill bits you’re buying for working on metal are also HSS with a different coating and probably different tip geometry.

    End mills are milling/lathe inserts can be HSS or carbide, also with some tungsten coating. Importantly, these are sintered, and made out of dust.

    Tungsten carbide is waaaay too brittle to work as a drill bit.





  • Calling it mental illness isn’t just a stretch it’s just fuckin wrong my dude. I get what you’re saying but bro, that’s just how humans work.

    For the vast majority of people, belief in science isn’t fundamentally different than belief in religion. Very few people actually know. The rest of us are taking it on faith that the scientific method is working. Even when it isn’t (that’s a fascinating story, btw, a lot of scientists confirmed findings before it was ultimately debunked.)

    Taking things on faith is part of why we work as a species, knowing a thing to be true without ever seeing it is critical to a functioning culture.

    The fact that that well has been poisoned with bullshit is a natural consequence.
