What Is The Difference Between Single Edge Spiral Milling Cutter And Double Edge Spiral Milling Cutter

The cutting efficiency of single edge milling cutter is low, because there is less one edge at the same speed

However, the finish of the machined surface is good, because a blade will not be pitted

The double edge milling cutter has high cutting efficiency, but the machined surface may be slightly poor due to the difference of cutting angle and cutting height between the two edges
