Standard square end to create sharp corners in finishing operations Premium high speed steel improves rigidity, hardness and wear resistance for milling of easy to medium machinability materials Multi-flute, three and four flute design allows for proper chip evacuation through a variety of materials and applications while maximizing machine performance when possible

Corner radius protects corners during tool entry and roughing operations in difficult to machine materials by preventing corner chipping and tool failure Premium micro-grain carbide substrate resists chipping, tool deflection, and has a high transverse rupture strength for greater feeds and speeds Three flute design improves chip formation and evacuation
