SDF-G Series Solid Tungsten Carbide General-Purpose 4-Flute Radius End Mill with ALCRONA Coating, HRC45

1. Material and Hardness: The milling cutter is made from solid tungsten carbide, ensuring extremely high hardness and excellent wear resistance. Tungsten carbide maintains stable performance under high-intensity and high-speed cutting conditions, suitable for demanding machining environments. This material not only extends the tool’s lifespan but also ensures consistent cutting performance over extended use. It is particularly suited for applications requiring high hardness and wear resistance.
2. Design Features:
   • Four-Flute Structure: Each flute handles a portion of the cutting work, gradually completing the machining process to ensure efficient material removal and superior surface quality. The four-flute design increases cutting speed and feed rate while reducing vibration and deformation, enhancing machining accuracy.
   • Optimized Geometry: The geometry of the milling cutter is optimized to ensure efficient chip evacuation and minimal cutting resistance. This improves cutting efficiency and reduces wear on both the tool and the workpiece, extending tool life.
   • Radius Cutting Edge: The specially designed radius cutting edge (Radius End Mill) provides smooth material transition, reducing stress concentration. It is ideal for machining complex radii and fillets, offering better surface finish and higher machining precision.
3. Coating Technology:
   • ALCRONA Coating: The surface is coated with ALCRONA coating, providing high hardness, low friction, and superior thermal stability, significantly enhancing cutting force and tool life. The ALCRONA coating effectively reduces cutting temperatures, minimizes thermal deformation, and improves machining quality and tool life. Additionally, the coating offers excellent lubrication properties, further reducing cutting resistance.
