Often, drilling through metal takes a specific bit, and forget about it threading it for you. But the takes a more awesome tact: it straight up melts the hole into the metal, threads it, and creates a thick metal ring on top. The drill can reach 1,652 degrees Fahrenheit, making it good for a variety of metals.
The starter kit begins around $750, meaning this is no small investment and isn't exactly going to be a random thing to throw in your cart at the hardware store. But it's a neat way to make metal working easier, all through the power of friction and some hot, hot temperatures that can melt steel. Plus, you can thread a bolt right through it after.
