|Unusual tungsten carbide drill bit.|
This is a very pretty, and unusual, tungsten carbide drill bit meant for drilling ceramic tile. Most such bits have a single spear-point-shaped piece of carbide brazed to a steel shank. This bit has four pieces brazed together to form a square. Presumably it cuts more smoothly and gives a rounder hole, though I can't say I've actually tried using one like this. It's too pretty for that.
