What kind of material can a circular saw cut?

Not all metal-cutting circular saw blades will cut thin sheet materials such a roofing and metal trim. To cut thin materials, you need a blade with more teeth and a tooth configuration that will not grab and tear, but that will act like a sheet metal nibbler.

What should the depth of a circular saw be?

If you’re sawing a piece of lumber that’s 1 in (2.5 cm) thick, for example, you’d set your blade to a depth of 1.125–1.25 in (2.86–3.18 cm). Setting the saw blade to the correct depth will ensure cleaner cuts and reduce friction, which can wear down the teeth and leave imperfections in the surface of your material.

When to use 45 degree angle on circular saw?

It corresponds to the position of the blade when it's set to 90 degrees, and should be used any time you’re making a normal cut. The line labelled "45" on the righthand side of the notch is for making beveled cuts at a precise 45-degree angle. Activate the saw blade by pulling the trigger on the rear handle.
