Single-edged milling cutters have low cutting efficiency because one blade is less at the same speed
But the surface finish is good, because a blade is definitely not pitted.
Double-edged milling cutters have high cutting efficiency, but the machining surface may be slightly worse due to the difference in cutting angle and cutting height between the two blades.
