Circular Saw

The circular blade rotates to cut accurate, straight lines. Depending on the blade, it can cut wood, sheet metal, framing, concrete and masonry. The blade’s radius dictates the depth of cut possible. Blades are not changed often — a multipurpose blade can usually handle most cutting requirements.

Circular Saw Blades

The type of material that a circular saw can cut depends on the blade. The blade's radius dictates the depth of the cut. A specially designed wrench is usually needed to replace a blade. Follow the owner's manual for details. The teeth on the nail-cutting blade (left) can cut wood with nails in it. The standard blade (middle) is made from hard steel with a tungsten-carbide tip, and the teeth on the long-life blade (right) are treated for smooth operation.

Step 1: Using a Circular Saw

Adjust the depth setting accordingly.

Step 2: Using a Circular Saw

Hold the saw with two hands to enable you to control it and switch it on. Allow the blade to reach full speed before beginning a cut.

Step 3: Using a Circular Saw

Align the relevant notch in the front of the base plate with the marked guide line, and apply even pressure as the cut progresses.
