a working portion configured to perform an operation on a workpiece; and
a mounting portion configured to be clamped between a clamping flange and a spindle head of a tool holder of the oscillating power tool, the mounting portion including
a first clamping face that is configured to abut the clamping flange, and
a second clamping face that is spaced apart from the first clamping face and faces away from the first clamping face, the second clamping face being configured to abut the spindle head,
a spindle slot that extends in an axial direction through the mounting portion from the first clamping face to the second clamping face, the spindle slot configured to accommodate a spindle of the oscillating power tool, and
pin openings that extend in the axial direction through the mounting portion from the first clamping face to the second clamping face, the pin openings being arranged around the spindle slot so as to be spaced apart from the spindle slot, the pin openings forming a closed section when the mounting portion is viewed in a direction parallel to the axial direction and is configured to receive pins which are arranged around the spindle of the oscillating power tool,
wherein
 when viewed in a cross section that is perpendicular to the first clamping face, at least a portion of opposed surfaces of at least one pin opening are non-parallel.
