Drill Bits

We just learned a little about Drilling.

When using the drill, the tool that goes at the end is called the drill bit.

There are lots of different types of drill bits, some that are used for cutting wood, some that are used for cutting metal or cement.

Depending on what is being drilled, the bits can be made of different things.
Most drill bits are made of steel, but many are made of titanium, tungsten, or even diamond tips.
