Developed for steel and stainless steel applications, CoroMill® Plura HFS End Mills utilize complete cutting length to achieve higher metal removal rate with small diameters compared to indexable milling and traditional milling strategies. Unequal helix flute design assures variable angular pitch in every axial section to maximize chatter-free material removal, while asymmetrical chip-breaker profile optimizes chip evacuation and minimizes risk of edge chipping and tool breakage.
