High Efficiency Milling (HEM) - also called trochoidal milling, dynamic milling, or high-speed machining - is a cutting strategy that dramatically increases material removal rates while extending tool life. By limiting radial engagement to 10-25% of tool diameter and increasing axial depth to 1-3× diameter, HEM strategies reduce cutting forces, manage heat more effectively, and allow significantly higher feed rates. The Daxer Carbide HEM series is engineered specifically for this strategy.
