The size of a portable electric circular saw is determined by the ___.

• A. Motor horsepower
• B. Diameter of the blade
• C. Weight
• D. Depth of cut

Answer: (B)

Blade diameter determines the size of a portable electric circular saw. The size you see labeled in catalogs and on the tool itself is the diameter of the blade it uses, with common sizes like 7-1/4 inches, 5-1/2 inches, or 4-1/2 inches. That measurement defines not only how the tool is categorized but also how deep you can cut in one pass—the larger the blade, the deeper the cut. Motor horsepower affects how smoothly and quickly the saw can cut through tougher material, but it doesn’t change how the tool is sized. Weight influences portability, not the size classification. Depth of cut is adjustable, and while it increases with larger blades, it’s a result of the blade size, not the primary way the tool’s size is described.
