What Factors Determine End Mill Angle? Using a big helix angle end mill is beneficial to prolong the tool's life when working with stainless steel materials because they have low thermal conductivity and a significant impact on the cutting edge's ability to transmit heat. The helix angle alters the features of a finished machined surface.
