High-Efficiency Performance Milling (HEPM)
HEPM series milling cutters are designed for side-cutting and trochoidal toolpaths only. High-efficiency milling and high-speed milling toolpaths subject the end mill to a light radial depth of cut (Ae) and heavy axial depth of cut (Ap) at high feedrates, with reduced tool stepover for more radial passes. This dramatically increases the material removal rate, while decreasing cutting pressure, reducing and dispersing heat, reducing tool wear, and improving surface finish.
Constructed of premium-grade micrograin carbide, these 6-flute end mills feature a 45° helix angle for higher productivity and longer tool life, and unequal flute indexing to reduce harmonic vibrations (chatter) and improve surface finishes. These tools utilize a unique chip splitter that reduces chip length by up to two-thirds. Combined with chip thinning, high-efficiency milling, and high-speed machining toolpaths, these tools provide superior chip evacuation to carry heat away from the tool and workpiece.
Aluminum Chromium Nitride (Hybrid AlCrN) reduces wear and increases heat resistance. These end mills are ideal for high-speed machining and high-efficiency milling of steels, stainless steels, cast iron, and high-temp alloys for increased material removal rates and fine surface finishes.
