How does a circular saw spin?

The saw’s motor runs the blade rotation in a way that the circular saw teeth direction points up as it enters the wood you’re cutting. … That rotation direction pulls sawdust and chips up into the guard where they can eject through a dust port. It’s the opposite of a table saw, where the teeth enter the cut from the top.

Do circular saws cut up or down?
