Circular saw blades whose cutting portion is made of steel — including slitting and slotting variants — serve construction, woodworking, and light metalworking applications and represent one of the most actively traded saw blade categories. The steel-working-part specification is the key boundary: blades tipped with carbide, diamond, or other non-steel materials fall instead under the adjacent non-steel category. Section 301 tariffs have applied to circular saw blades from certain origins, and accurate material certification is important for both classification and trade-remedy compliance.
