Abstract (en)

An improved grinding, or cutting disc, for a hand power tool, e.g. an angle grinder, has aerodynamic holes (20) for an enhanced airflow through the disc to the extract ducts remove grinding dust and grit. The extract holes can be rounded, oval or any suitable shape and with sloping edges to enhance the blower effect, and are positioned between the central mounting hole (12) and the outer rim (14).
