If you see someone misusing tools, appliances or small children apparently unaware of how stupid they're being, please tell them. And write it up here, '''at the top where new entries will be read''', in the hope that someone else will learn, too.

The 'Space has examples of all three. In general metal drill bits are a simple spiral and often labelled HSS (this is often engraved, along with a diameter on the barrel of the bit, don't always trust the box). Masonry bits will have a blunt 'spade' on the tip. Wood bits tend to have a small point at the tip and spurs, they can also be used for plastics. | ||
In general use the right type of drill bit. If a bit is carbon steel it is probably too brittle for metal. | In general use the right type of drill bit. If a bit is carbon steel it is probably too brittle for metal. | ||
